Full textAbstract:
The intelligent development of coal mines is a crucial way to achieve the safe, efficient, green, and low-carbon transformation of the coal industry and to reach the “double carbon” target, which is related to the life and health of miners, the stable development of enterprises and the national energy reform. As directly affected subjects, the cooperative attitudes of miners in different emotional states have a significant impact on the smooth implementation of intelligent coal mine renovation projects. Hence, we combined the RDEU theory and game theory, constructed a three-party evolutionary game model of the small and medium-sized energy enterprises (SMEE), the government, and the miner, considered the influence of the strategies made by the miner on the equilibrium strategy choices of other game subjects in the intelligent coal mine construction under the rational and irrational emotional states of the miner, and finally used MATLAB 2021 to simulate and analyze the impact of the evolution of the gaming system from 3 key elements: initial participation rate, construction costs, and government support. The study found the following: (1) The government will insist on actively promoting intelligent coal mine construction regardless of the miner’s emotional state. (2) Both moderate pessimism and optimism will, to a certain extent, give a positive impetus to the development of intelligent coal mine construction. (3) The miner’s emotions have a greater impact on SMEE than on the government’s strategic behavior. (4) Excessive construction costs or low government support will make SMEE may reduce the enthusiasm of SMEE to carry out an intelligent construction of coal mines. Accordingly, corresponding suggestions and countermeasures are put forward, aiming to provide targeted and practical ideas for the efficient construction of intelligent coal mines in China, thereby accelerating the green and low-carbon transformation of energy.

The task of ensuring worker safety in underground coal mines has never been simple. It has always been challenging to ensure worker safety in underground coal mines. Coal miners are seriously injured or killed as a result of numerous fatal and non-fatal accidents all over the world. Accidents occur as a result of lack of monitoring of mining areas and failure to implement proper safety measures. In this review, the coal miner's smart wearable safety device is implemented. A smart wearable safety device that will monitor the miner's health and provides precautionary measures for the miner's safety has been developed with the advent of the Industrial Internet of Things (IIoT). Integrating smart wearable safety devices with various health sensors such as a pulse rate sensor, temperature sensor, blood oxygen sensor, gas sensor, and camera, and then connecting it to Node MCU, and the internet enhances the safety of coal miners. Sensors constantly transmit sensor data to the cloud, and if an unusual situation arises, it notifies the responsible person in the control room as well as the miners. Since deep underground mining is especially susceptible to toxic gases, low levels of oxygen, and hazardous gases, the MQ gas sensor family can detect them. The proposed system is primarily used to improve working conditions inside coal mines and to ensure workers' safety.

Full textAbstract:
Coal mining is a hazardous profession in India that exposes workers to a range of health risks, including respiratory diseases, skin disorders, hearing loss, and injuries. The coal miner's day, observed on May 4th every year, commemorates the hard work and sacrifices of coal miners. The mines act, 1952, and its associated regulations mandate the provision of medical facilities, safety and health measures, and rescue stations and trained personnel for the rescue of workers. The coal mines (Conservation and development) act, 1974, mandates the conservation of coal resources and the development of coal mines while ensuring the safety and health of workers. However, the implementation of these laws has been inadequate in many cases, leading to a high prevalence of occupational diseases among coal miners. The lack of proper implementation of safety and health regulations has been identified as a key factor contributing to the high prevalence of occupational diseases. Additionally, the existing regulations do not address the specific safety and health issues associated with the use of automation and robotics in mining. To safeguard the health and safety of coal miners, more efforts are needed to ensure the effective implementation of these laws and to provide adequate medical support and rehabilitation services. Prioritizing the health and well-being of coal miners can pay tribute to their contribution to society while promoting a safer and healthier workplace for all.

Full textAbstract:
This paper analyzes the management system of safety partnership in coal mining enterprises through the methods of evolutionary game and optimized behavioral propagation of SEIR, considering the miners’ benefits and losses, as well as the influencing factors from miners and enterprises. It is found that, under the influence of the management system of safety partnership within miners, after the evolutionary game between miner partners, the behavioral strategies and personal benefits of the two miners are both consistent. Moreover, the benefits of individual miner and overall benefits of two miner partners, will affect the miners’ choice of safe behavioral strategies, as a result of which, the coal mines could improve the miners’ benefits through the management system of safety partnership to stimulate the implementation of miners’ safe behavior. Additionally, under the incentive of the management system of the safety partnership, the number of miners implementing unsafe behavior is decreasing, while the number of miners who are not easily affected by unsafe behavior is increasing. When the rewards and punishments of miners are strengthened, the propagation of miners’ safe behavior is accelerated. Finally, the propagation of miners’ safe behavior has a certain spillover effect within a certain range. The results of this paper provide a theoretical basis for the implementation of the management system of safety partnership in coal mining enterprises, which helps enterprises in guiding miners to take up safe behavior, which is better for enterprises’ safe development.

Full textAbstract:
The unsafe behavior of miners seriously affects the safety of deep mining. A comprehensive evaluation of miners’ unsafe behavior in deep coal mines can prevent coal mine accidents. This study combines HFACS-CM, SEM, and SD models to evaluate miners’ unsafe behaviors in deep coal mining. First, the HFACS-CM model identifies the risk factors affecting miners’ unsafe behavior in deep coal mines. Second, SEM was used to analyze the interaction between risk factors and miners’ unsafe behavior. Finally, the SD model was used to simulate the sensitivity of each risk factor to miners’ unsafe behavior to explore the best prevention and control strategies for unsafe behavior. The results showed that (1) environmental factors, organizational influence, unsafe supervision, and unsafe state of miners are the four main risk factors affecting the unsafe behavior of miners in deep coal mines. Among them, the unsafe state of miners is the most critical risk factor. (2) Environmental factors, organizational influence, unsafe supervision, and the unsafe state of miners have both direct and indirect impacts on unsafe behaviors, and their immediate effects are far more significant than their indirect influence. (3) Environmental factors, organizational influence, and unsafe supervision positively impact miners’ unsafe behavior through the mediating effect of miners’ unsafe states. (4) Mental state, physiological state, business abilities, resource management, and organizational climate were the top five risk factors affecting miners’ unsafe behaviors. Taking measures to improve the adverse environmental factors, strengthening the organization’s supervision and management, and improving the unsafe state of miners can effectively reduce the risk of miners’ unsafe behavior in deep coal mines. This study provides a new idea and method for preventing and controlling the unsafe behavior of miners in deep coal mines.

Full textAbstract:
Background: Studies have indicated that coal miners in China have higher levels of perceived job stress. However, few studies have investigated the work stress structure of coal miners. Objective: Our study focused on the work stress of coal miners in China, with a primary aim to determine the work stress structure of coal miners in China using a mixed-methods approach. Methods: Semi-structured interviews were performed with thirty-three people (team leaders and frontline coal miners) conducted with participants from various state-owned large- and medium-sized coal mines in China. Grounded theory was used to construct an initial model for the concept of coal miners’ work stress. Using the results of this initial survey and findings in the existing literature, we then constructed a preliminary questionnaire regarding coal miners’ work stress and administered the questionnaire to 900 coal miners in the Shaanxi, Henan, Inner Mongolia, and Gansu provinces. Results: The results show that the work stress structure for coal miners differs from that for other occupational types in China, due to differences in the Chinese culture and foreign cultural influences. We revised our questionnaire based on these considerations and administered a new survey to the frontline production workers in coal mines. The preliminary questionnaires were revised and analyzed through exploratory and confirmatory factor analysis, resulting in a final formal model for work stress, which was supported by content and structural validity. Conclusion: In this research, we used the framework of grounded theory to conduct an empirical analysis of the structure model of coal miners’ work stress. The findings support that the primary work stress factors of Chinese coal miners included the stress of the work environment, job responsibility, interpersonal relationships, career development, the family environment, and organizational systems. Coal enterprises should therefore always take these factors into consideration when developing and implementing safety management policies aimed at to improve the occupational health status of coal miners.

Pneumoconiosis of workers in brown coal mines is an occupational disease, a global public health problem and a serious disease of the lung parenchyma. If it is not prevented, it leads to irreversible changes in the lungs with complications. The disorder occurs after prolonged exposure to coal dust containing high concentration of free crystalline silica. Data in literature regarding its health impact on people working in coal mines are relatively scarce. Recently, there has been an increase in miners' pneumoconiosis, which requires a stricter policy to protect workers in the mines. There are two classical types of CWP: simple and complicated. The main diagnostic method of CWP is based on a specific X-ray finding, and the auxiliary method of choice is spirometry. The pathophysiological mechanism of CWP formation is not fully known, although it has been shown that damage to the lung parenchyma goes through three phases caused by effect of lung cells exposure to coal dust. Studies show that cytokines play an important role in inflammation and the immune response as mediators of toxic and pathogenic effects in CWP. A link between exposure to coal dust in brown coal mines and the development of CWP has also been demonstrated, with a consequent reduction in the physical and psychological quality of life of workers in the mines.

The hoist cage is used to lift miners in a coal mine’s auxiliary shaft. Monitoring miners’ unsafe behaviors and their status in the hoist cage is crucial to production safety in coal mines. In this study, a visual detection model is proposed to estimate the number and categories of miners, and to identify whether the miners are wearing helmets and whether they have fallen in the hoist cage. A dataset with eight categories of miners’ statuses in hoist cages was developed for training and validating the model. Using the dataset, the classical models were trained for comparison, from which the YOLOv5s model was selected to be the basic model. Due to small-sized targets, poor lighting conditions, and coal dust and shelter, the detection accuracy of the Yolov5s model was only 89.2%. To obtain better detection accuracy, k-means++ clustering algorithm, a BiFPN-based feature fusion network, the convolutional block attention module (CBAM), and a CIoU loss function were proposed to improve the YOLOv5s model, and an attentional multi-scale cascaded feature fusion-based YOLOv5s model (AMCFF-YOLOv5s) was subsequently developed. The training results on the self-built dataset indicate that its detection accuracy increased to 97.6%. Moreover, the AMCFF-YOLOv5s model was proven to be robust to noise and light.

Ability to monitor vital signs and determine the location of a particular miner in real time. Methods. The communication systems used today in the coal industry have come a long way since their development. Most mines use outdated communication systems between a dispatcher and miners. Working safely in the coal industry is extremely important. The requirements for the control of data collection for observation, monitoring and exchange of information in real time should grow with the improvement of the technical capabilities of positioning systems and move to a higher level of control of individual health parameters. Results. The article analyzes the used systems and methods of positioning miners. The advantages and disadvantages of the existing systems for monitoring the technological indicators of coal mines, the optimal technology of data transmission and determining the location of an underground worker have been established. The directions of further research on improving the control of vital activity indicators, the possibility of prompt transmission of a signal to the dispatcher in the event of an emergency, and individual personalization of the miner based on RFID technologies have been determined. The practical value of the obtained results lies in the functional addition of the used systems, which allows timely and highly accurate rescue blocked miners with the possibility of tracking their condition indicators. Scientific novelty. The article offers a new functionality and structure of an automated subsystem for monitoring and controlling the technological indicators of mining pits of coal mines, which differ from the existing personal monitoring of vital indicators of workers in real time due to the use of active RFID tags embedded in separate devices.

Introduction. Due to the impact of adverse working conditions and climate, workers in coal-mining enterprises in the Arctic are at increased risk of occupational diseases (OD).The aim of the study was to study the working conditions, causes, structure and prevalence of occupational diseases in miners of coal mines in the Arctic.Materials and methods. Th e data of social and hygienic monitoring “Working conditions and occupational morbidity” of the population of Vorkuta and Chukotka Autonomous District in 2007–2017 are studied.Results. It was established that in 2007–2017 years, 2,296 ODs were diagnosed for the first time in 1851 coal mines, mainly in the drifters, clearing face miners, repairmen and machinists of mining excavating machines. Most often, the ODs occurred when exposed to the severity of labor, fibrogenic aerosols and hand-arm vibration. The development of professional pathology in 98% of cases was due to design flaws of machines and mechanisms, as well as imperfections of workplaces and technological processes. Diseases of the musculoskeletal system (36.2%), respiratory organs (28.9%) and nervous system (22.5%) prevailed in the structure of professional pathology of miners of coal mines. Among the three most common nosological forms of OD were radiculopathy (32.1%), chronic bronchitis (27.7%) and mono-polyneuropathy (15.4%). In 2017, coal miners in the Arctic had a professional morbidity rate of 2.82 times higher than the national rates for coal mining.Conclusions. To preserve the health of miners of coal mining enterprises, technical measures to improve working conditions and medical interventions aimed at increasing the body’s resistance to the effects of harmful production and climatic factors are necessary.

Miners’ unsafe behavior is the main cause of roof accidents in coal mines, and behavior intervention plays a significant role in reducing the occurrence of miners’ unsafe behavior. However, traditional behavior intervention methods lack pertinence. In order to improve the intervention effect and reduce the occurrence of coal mine roof accidents more effectively, this study proposed a targeted intervention method for unsafe behavior. The process of targeted intervention node locating was constructed, and based on the analysis of 331 coal mine roof accidents in China, three kinds of targeted intervention nodes were located. The effectiveness of targeted intervention nodes was evaluated by using structural equation model (SEM) through randomly distributing questionnaires to miners of Pingdingshan coal. The results show that, in preventing roof accidents of coal mines, the targeted intervention nodes have a significant positive impact on the intervention effect. The method can also be applied to the safety management of other industries by adjusting the node location and evaluation process.

Abstract. The profession of a miner is one of the most dangerous in the world. Among the main causes of fatalities in underground coal mines are the delayed alert of the accident and the lack of information regarding the actual location of the miners after the accident. In an emergency situation (failure or destruction of underground infrastructure), personnel search behind and beneath blockage needs to be performed urgently. However, none of the standard technologies – radio-frequency identification (RFID), Digital Enhanced Cordless Telecommunications (DECT), Wi-Fi, emitting cables, which use the stationary technical devices in mines – provide information about the miners location with the necessary precision. The only technology that is able to provide guaranteed delivery of messages to mine personnel, regardless of their location and under any destruction in the mine, is low-frequency radio technology, which is able to operate through the thickness of rocks even if they are wet. The proposed new system for miner localization is based on solving the inverse problem of determining the magnetic field source coordinates using the data of magnetic field measurements. This approach is based on the measurement of the magnetic field radiated by the miner's responder beacon using two fixed and spaced three-component magnetic field receivers and the inverse problem solution. As a result, a working model of the system for miner's beacon search and localization (MILES – MIner's Location Emergency System) was developed and successfully tested. This paper presents the most important aspects of this development and the results of experimental tests.

There is a large number of jobs in Poland, the performance of which involves working in difficult, arduous conditions. Such jobs include probably the work of miners in hard coal mines. They often go to the mine several times a week for many years. They work several hundred meters underground in the dark, high temperature, humidity, dust and noise with loud machines. Such extreme working conditions cause many occupational diseases caused by these conditions and even life threatening. The total number of accidents in the whole mining has decreased at the turn of the last years, however, in the hard coal mining itself, it remains at a similar level. When performing work in such difficult conditions, the miner should know well and, above all, observe the work safety regulations. The appropriate organizational culture enables, among others shaping the level of safety culture and improving working conditions [2, 14, 19, 25, 26]. Therefore, miners should be constantly motivated to work safely, but also rewarded. The results of the literature analysis of the subject were supported by own research in the scope of the subject of comfort of life and work in the assessment of the professional group of energy sector employees on the example of a mining enterprise. The research was carried out among miners, in one of the Polish mines. They were intended to show the magnitude of the problem of discomfort in the work of a professional group of miners in hard coal mining, as well as comfort of life and motivation for a safe working mode.

This study attempts to construe the first-ever coalmine-oriented Bengali fiction from a social, historical, and geographic perspective. Sailjananda Mukhopadhyay wrote Koylakuthi (the coal miners’ office) in 1922, representing Bengal’s coal mines. This study aims to reconstruct the miners’ society from the early 20th Century with narratives from this story and examine the societal challenges and changes a hundred years apart. A comparative study of the mining geo-cultural landscape of the 1920s Bengal and its contemporary counterpart is carried out. Changed geography, technology, and community are observed. And it reveals that areal expansion of the coalfields has increased production, and technological advancement has increased the safety and security of the miner class. However, the labour structure, class and caste hierarchy, and patriarchal mindset have hardly changed.

Full textAbstract:
Context.—Coal worker's pneumoconiosis is a major occupational lung disease in the United States. The disease is primarily controlled through reducing dust exposure in coal mines using technological improvements and through the establishment of dust standards by regulatory means. Objective.—To determine if dust standards established in the US Federal Coal Mine Health and Safety Act of 1969 have reduced the prevalence and severity of coal worker's pneumoconiosis. Design.—The study population included materials from 6103 deceased coal miners submitted to the National Coal Workers' Autopsy Study from 1971 through 1996. Type and severity of coal worker's pneumoconiosis were classified using standardized diagnostic criteria. Results.—Among miners who worked exclusively prior to the 1969 dust standard, 82.6% had coal macules, 46.3% coal nodules, 28.2% silicotic nodules, and 10.3% progressive massive fibrosis. Lower prevalences were noted among miners exposed exclusively to post-1970 dust levels: 58.8% had coal macules, 15.0% coal nodules, 8.0% silicotic nodules, and 1.2% progressive massive fibrosis. The differences in prevalence were highly significant (P < .001) for all types of pneumoconiosis, including progressive massive fibrosis, after adjustment for age, years of mining, and smoking status. Conclusions.—The study confirms a beneficial impact of the first 25 years of the dust standard established by the 1969 act on the prevalence and severity of coal worker's pneumoconiosis in US coal miners. However, pneumoconiosis continues to occur among miners who have worked entirely within the contemporary standard, suggesting a need for further reductions in exposure to respirable coal mine dust.

AbstractThe aim of this study was to assess DNA damage in Turkish coal miners with the buccal micronucleus cytome (BMCyt assay as the least invasive and therefore most practical method that may find wider application in coal miner biomonitoring. Buccal epithelial cell samples were taken from 54 coal miners and 42 controls from Zonguldak, Turkey to establish their micronucleus (MN), binucleus (BN), condensed chromatin (CC), karyorrhectic (KHC), karyolytic (KYL), nuclear bud (NBUD), and pyknotic (PYC) frequencies. We also analysed the effects of confounding factors such as age, years of work at the mine, smoking, alcohol drinking, and use of protective equipment on differences in MN frequencies. Two miners had confirmed and three suspect pneumoconiosis, whereas 49 displayed normal chest radiographs. MN, BN, KHC, and NBUD frequencies were significantly higher in coal miners than controls. Years of work at the mine also showed a significant effect on buccal MN frequencies in coal miners, but we found no correlation between MN frequencies and age, smoking, and alcohol consumption. In conclusion, BMCyt assay proved itself an accurate and practical screening method, as it can detect DNA damage much earlier than pneumoconiosis develops.

Full textAbstract:
This paper, drawing on a questionnaire survey conducted among 587 coal miners from six coal mines, seeks to ascertain whether the Polish coal mining industry is committed to organizational greening and whether its employees behave in environmentally responsible ways. Specifically, it explores—by means of hierarchical linear modeling (HLM)—the direct effects of green organizational climates on miners’ pro-environmental conduct at home and at work. We found that climates had a direct effect on employee behavior in and outside the workplace, and that personal environmental values were positively related to the latter variable. However, it has to be admitted that the actual engagement of coal miners in voluntary pro-environmental action at work was not very deep. Crucially, it turned out that, in two coal mines, there were strong green climates, while the rest were weak, which suggests differences in terms of commitment to organizational greening throughout the industry. The present paper explores the significance of the results and highlights the applicability of our methodological approach to the study of employee involvement in organizational pro-environmental action.

Full textAbstract:
Air quality related to respiratory illness is examined in many settings, including populations that work or reside close to sources of pollution. Industry produced pollution from mining and metal manufacturing, natural environmental pollution as in the case of bushfires and large-scale dust storms are examples. We reviewed any available literature and data concerning the Queensland coal industry and its effect on respiratory health of miners, mining related workers and communities in proximity to coal mines. We searched various databases using keywords related to coal and respiratory diseases, using the five step criteria defined by Denyer and Tranfield. In the Queensland coal mining industry, the negative effect of mining on workers’ respiratory health has been known for many years and has received increased attention in the last five years both nationally and internationally due to the resurgence in Coal Mine Dust Lung Diseases and specifically Coal Worker’s Pneumoconiosis (CWP). A Queensland parliamentary review has prompted regulatory amendments for the permitted (occupational) exposure level (PEL; OEL) to coal dust and silica; amendments have also been enacted for better occupational respiratory health surveillance of Queensland coal miners, both surface and underground. Considering Queensland has a high proportion of Australian coal mines, the literature available on respiratory health in Queensland coal mines and surrounding communities is minimal. There is very limited research into, and possible underreporting of CMDLD amongst the coal mining workers in Queensland. Further studies are required to better understand air pollution and health effects in coal miners in Queensland.

Full textAbstract:
Although numerous studies have confirmed the important influence of values on employees’ behavior, less is known about the relationship between work values and miners’ safe behavior. Based on self-verification theory and trait activation theory, this study constructed a structural equation model to explore the effect of work values on miners’ safety behavior, using psychological empowerment as a mediating variable and safety climate as a moderating variable. Data were collected from 207 miners in three coal mines in China. The model was examined using a hierarchical regression analysis and the bootstrapping method. The results showed that three types of work values significantly and positively predicted miners’ safety behavior, and psychological empowerment mediated the relationship between work values and miners’ safety behavior. However, the moderating role of safety climate was not supported. The results enrich the boundary conditions under which work values influence miners’ safety behavior and provide coal managers with intervention measures such as cultivating miners’ work values and psychological empowerment, which can improve miners’ safety behavior.

Full textAbstract:
Most coal mine accidents are attributed to the unsafe behavior of miners. Adjusting the safety attitude and thus improving miners’ safety behavior is important for accident prevention. However, the relationship between safety attitude and safety behavior in the coal mining industry has not been explored. The coal miners’ safety attitude scale and safety behavior scale were used to analyze the impact of safety attitude on safety behavior and investigate the correlation between four dimensions of safety attitude and two kinds of safety behavior. The impact of demographic characteristics including age, length of service, and education level on safety attitude and safety behavior was also measured. A survey of miners at four coal mines in China resulted in 593 valid responses. The result indicates that safety attitude is not only positively related to safety behavior but also positively related to safety participation and safety compliance. From the four dimensions of safety attitude, the team safety climate directly affects safety participation and safety compliance. Management safety commitment, job stress, and fatalism are not significantly related to safety participation and safety compliance. The results show that age and length of service were slightly related to safety attitude, and the education level was not significantly related to safety attitude. Age, length of service and education level had no impact on safety behavior. The contribution of this study to the current literature is that the safety attitude of coal miners can positively affect safety behavior and can be improved by fostering a good team safety climate. Practical implications emphasize safety training and safety education, especially for young miners. Managers should reinforce safety commitment, provide adequate safety equipment, timely communicate with miners, and encourage miners to actively communicate with colleagues to improve safety behavior and prevent accident in the coal mining industry.

For the requirements of complex environment and safe-management in the coal mine, this paper presents a new Panoramic Vision Mine Safety Monitoring System Based on WLAN. the monitoring system use a binocular omni-directional vision sensor(ODVS)[1] coordinated with the WLAN or LAN network to transmit images, information, commands or data. The system can also get the panoramic vision in the coal mine from any miner at any time. The miners’ identities will be binding with the ODVS and WLAN protocol. Then the monitoring system will use the binding information to position and track miners. This is a new reliable monitoring system which can monitor the coal mine environment security, the coal mine producing security, the coal mine transport security, the miner security at the same time, and these provide the system with expecting application value and market outlook.

Working in coal mines, despite all achievements of modern science and technology, still remains among the most dangerous occupations to the health. The review of researches about the chromosomal damage in coal miners was performed. We searched information in the following databases - PubMed, http://www.sciencedirect.com and in the electronic library http://elibrary.ru with the use of the search strategy adopted in the Cochrane Collaboration. Inclusion criteria were: 1) randomized, controlled original researches; 2) researches performed in 1993-2016 where coal miners were the object of the study; 3) articles described chromosomal aberrations (CAs), micronuclei (MN), sister chromatid exchanges (SCE), DNA comets as biomarkers of the exposure. Exclusion criteria were other methods of the assessment of DNA damage; lack of data on the type of mines or coal mines/open-cast mines (uranium, tin, etc.); lack of access to the full text in Russian or English. As a result of the search 12 articles met selection criteria and showed a chromosomal damage in miners were selected. The results of researches performed in different countries (Russia, Turkey, Brazil, Colombia, Netherlands, Peru and India) demonstrate the increased frequency of chromosomal abnormalities in employees of coal mining industry. Damages are accumulated in cells of different types (buccal epithelium and lymphocytes) and can be detected by methods of the assessment of CAs, SCE, MN and DNA comet assay that indicating the complex basis of genotoxicants. The results of the analysis of the relationship between the cytogenetic markers, age and length of service are contradictory. The formation of occupational pulmonary diseases is accompanied by an additional induction of cytogenetic damage. In general, the analysis confirmed the high genotoxic risk of working conditions in underground as well as open-cast miners.

Full textAbstract:
AbstractThe article proceeds from the observation that in the contemporary British cultural imagination, the figure of the coal miner tends to be presented as the embodiment of anti-urban and organicist qualities that in continental Europe are more commonly associated with the peasantry. Drawing on the theoretical insights of Raymond Williams, the article traces the genealogy of this ‘structure of feeling’ back to the time of the miners’ strike of 1984/85 and further back in the 1970s. It argues that the ‘ruralized’ miner was one imaginary in a complex power struggle over the ‘real’ identity of miners that was waged between the industry and the state, the National Union of Mineworkers (NUM) and the National Coal Board (NCB), and, crucially, inside the NUM itself. ‘Ruralization’ was most vigorously promoted by union militants who sought to displace an alternative vision, championed jointly by the Coal Board and union moderates, which had situated miners firmly at the heart of industrial modernity. It was only in the wake of the defeat of the miners in the 1984/85 strike, and during the subsequent cultural reworking of this strike, that this structure finally gained dominance.

AbstractIn the United States, an unexpected and severe increase in coal miners’ lung diseases in the late 1990s prompted researchers to investigate the causes of the disease resurgence. This study aims to scrutinize the effects of various mining parameters, including coal rank, mine size, mine operation type, coal seam height, and geographical location on the prevalence of coal worker's pneumoconiosis (CWP) in surface and underground coal mines. A comprehensive dataset was created using the U.S. Mine Safety and Health Administration (MSHA) Employment and Accident/Injury databases. The information was merged based on the mine ID by utilizing SQL data management software. A total number of 123,589 mine-year observations were included in the statistical analysis. Generalized Estimating Equation (GEE) model was used to conduct a statistical analysis on a total of 29,707, and 32,643 mine-year observations for underground and surface coal mines, respectively. The results of the econometrics approach revealed that coal workers in underground coal mines are at a greater risk of CWP comparing to those of surface coal operations. Furthermore, underground coal mines in the Appalachia and Interior regions are at a higher risk of CWP prevalence than the Western region. Surface coal mines in the Appalachian coal region are more likely to CWP development than miners in the Western region. The analysis also indicated that coal workers working in smaller mines are more vulnerable to CWP than those in large mine sizes. Furthermore, coal workers in thin-seam underground mine operations are more likely to develop CWP.

Full textAbstract:
An ongoing resurgence of occupational lung disease among coal miners in the United States has been linked to respirable crystalline silica (RCS). To better protect miners, a deeper understanding of key exposure factors is needed. As part of a larger investigation of RCS in 15 coal mines, this paper describes analysis of silica mass content in two types of samples: (1) respirable coal mine dust (RCMD) collected in standardized locations in each mine; and (2) respirable dust generated in the laboratory from primary source materials, including coal and rock strata being mined at the production face, material obtained from the dust collection system on roof bolter machines, and rock dust products being applied by the mine. As expected, results indicate that rock strata drilled for roof bolting or being extracted along with the coal are a major source of RCS in many coal mines—although the coal seam itself can contain significant silica in some mines. While silica content of rock strata encountered in central Appalachian mines is not necessarily higher than in other regions, the sheer abundance of rock being extracted in thin-seam central Appalachian mines can explain the relatively higher silica content typically observed in RCMD from this region.

Coal mine workers are exposed to a number of workplace hazards which may increase the risk of cancer and mortality. We conducted a systematic review and meta-analysis to investigate cancer and mortality in coal mine workers We searched in Ovid Medline, PubMed, Embase and Web of Science databases using keywords and text words related to coal mines, cancer and mortality and identified 36 full-text articles using predefined inclusion criteria. Each study’s quality was assessed using the Newcastle-Ottawa Scale. We performed random-effect meta-analyses including 21 of the identified articles evaluating cancer and/or mortality of coal mine workers. The meta-analysis showed an increased risk of all-cause mortality (SMR 1.14, 95% CI 1.00 to 1.30) and mortality from non-malignant respiratory disease (NMRD) (3.59, 95% CI 3.00 to 4.30) in cohorts with coal workers’ pneumoconiosis (CWP). We found a somewhat increased risk of stomach cancer (1.11, 95% CI 0.97 to 1.35) and of mortality from NMRD (1.26, 95% CI 0.99 to 1.61) in the cohorts of coal miners with unknown CWP status. The meta-analysis also showed a decreased risk of prostate cancer and cardiovascular and cerebrovascular mortality among coal miners. This may be a result of the healthy worker effect and possible lower smoking rates, and perhaps also reflect the physically active nature of many jobs in coal mines. The meta-analysis for lung cancer did not show increased risk in coal miners with CWP (1.49, 95% CI 0.70 to 3.18) or for coal miners of unknown CWP status (1.03, 95% CI 0.91 to 1.18). Lower smoking rates in coal mine workers could explain why case–control studies where smoking was controlled for showed higher risks for lung cancer than were seen in cohort studies. Coal mine workers are at increased risk of mortality from NMRD but decreased risk of prostate cancer and cardiovascular and cerebrovascular mortality. Studies of coal mine workers need long-term follow-up to identify increased mortality and cancer incidence.

Introduction.Coal dust and coal fi ring products contain large amounts of carcinogenic chemicals (specifically benz[a]pyrene) that are different in influence on workers of coal mines and thermal power plants. Specific immune reactions to benz[a]pyrene therefore in these categories of workers can have specific features.Objective.To reveal features of antibodies specifi c to benz[a]pyrene formation in workers of coal mines and thermal power plants.Materials and methods.The study covered A and G class antibodies against benz[a]pyrene (IgA-Bp and IgG-Bp) in serum of 705 males: 213 donors of Kemerovo blood transfusion center (group 1, reference); 293 miners(group 2) and 199 thermal power plant workers (group 3). Benz[a]pyrene conjugate with bovine serum albumin as an adsorbed antigen was subjected to immune-enzyme assay.Results.IgA-Bp levels in the miners (Me = 2.7) did not differ from those in the reference group (Me = 2.9), but in the thermal power plant workers (Me = 3.7) were reliably higher than those in healthy men and in the miners (p<0.0001). Levels of IgG-Bp in the miners (Me = 5.0) appeared to be lower than those in the reference group (Me = 6.4; (p = 0.05). IgG-Bb level in the thermal power plantworkers (Me = 7.4) exceeded the parameters in the healthy donors and the miners (p<0.0001). Non-industrial factors (age and smoking) appeared tohave no influence on specific immune reactions against benz[a]pyrene in the miners and the thermal power plant workers.Conclusions.Specific immune reactions against benz[a]pyrene in the miners and the thermal power plant workers are characterized by peculiarities: the miners demonstrate lower levels of class A serum antibodies to benz[a]pyrene; the thermal power plant workers present increased serum levels of class G antibodies to benz[a]pyrene. These peculiarities result from only the occupational features, but do not depend on such factors as age, smoking and length of service at hazardous production. It is expedient to study specific immune reactions to benz[a]pyrene in workers of coal mines and thermal power plants, to evaluate individual oncologic risk and if malignancies occur.

Full textAbstract:
The psychological health and work commitment of miners are prerequisites to ensuring their sustainable safety behavior, and it is also significant to the sustainable development of coal mines in China. In this context, we conducted a questionnaire survey among coal miners of state-owned coal enterprises to explore the relationships between cultural emotion, unemployment risk perception, Big Five personality traits, and work commitment. The results reveal that (1) cultural emotion and its three dimensions played a significant positive role in promoting work commitment. (2) Unemployment risk perception, policy unemployment risk perception, and individual differential unemployment risk perception had a negative moderating effect. (3) Moreover, work commitment was associated with differences in personality characteristics except for agreeableness. This research is of important theoretical value and practical significance, as it can guide Chinese coal miners to increase their work commitment and thereby improve safety in production.

Th e study covered serum IgG-Bp in 501 miners aged under 60 (161 healthy, not working in mine; 239 miners; 101 patients with lung cancer), by means of non-concurrent immune-enzyme analysis using benzo[a]pyrene conjugates with bovine serum albumin as an antigen. Findings are that increased levels of IgG-Bp in lung cancer patients are more frequent (50.5%) than in healthy men not working in mine (37.2%, p=0.047, OR=1.7) and in miners (30.5%, p=0.0008, OR=2.3). Length of service in mines did not infl uence serum levels of IgG-Bp in coal industry workers. In the miners, with age adjustment consideration, OR for lung cancer equaled 2.0 (p=0.01), and with adjustment for smoking OR=2.3 (p=0.001). Occupational (work in mine), lifestyle (smoking) and endogenous (age) factors do not have signifi cant infl uence on intensity of individual specifi c reaction to benzo[a]pyrene in males. Immunoassay of IgG-Bp is recommended for lung canc er diagnosis in coal mine workers.

IntroductionRespirable crystalline silica exposure has been implicated in the resurgence of coal workers’ pneumoconiosis (CWP) in the USA. A 2010 report found an increasing prevalence of r-type opacities, which are associated with silicosis lung pathology, on the radiographs of working underground coal miners in central Appalachia. This analysis updates that report by assessing the prevalence of r-type opacities during 2010–2018 compared with earlier decades.MethodsData from the Coal Workers’ Health Surveillance Program were used to calculate the prevalence of r-type opacities on radiographs of working underground coal miners. The data were restricted to radiographs taken during 1 January 1980 to 15 September 2018. The presence of r-type opacities was defined as an r-type classification for either the primary or secondary shape/size of small opacities. Prevalence ratios for r-type opacities were calculated using log binomial regression.ResultsRadiograph classifications for 106 506 miners were included in analysis. For the USA overall, the prevalence of r-type opacities among miners with radiographs taken during 2010–2018 compared with 1980–1989 has increased (PR 2.4; 95% CI 1.9 to 3.0). For central Appalachia, the proportion of r-type opacities observed increased when comparing 1980–1989 to 2010–2018 (PR 6.0; 95% CI 4.6 to 7.9).ConclusionsThe prevalence of r-type opacities on the radiographs of Appalachian underground coal miners continues to increase, implicating exposure to crystalline silica in respirable coal mine dust. The current findings underscore the importance of monitoring and controlling exposure to silica in coal mines.

Full textAbstract:
Coal dust is one of the most serious issues in coal mines. The miners at an excavation face have a high potential for exposure to high concentrations of coal dust. The main method for removing coal dust is by ventilation. To better control the coal dust at the excavation face, it is important to understand the coal dust movement patterns and distribution characteristics. This paper used the computational fluid dynamics (CFD) approach to simulate coal dust movement under two different ventilation systems. The Eulerian-Lagrange method was used to study the gas‒solid two-phase fluid behavior. The coal dust concentration distributions under the two ventilation systems are presented and further compared. From the comparison results, it is found that a vortex ventilation system has better coal dust removal performance. This ventilation system is recommended for excavation for better coal dust control and miners’ health protection.

Introduction. In 2021, the largest proportion of workers in the Russian Federation with class 3.1 and higher1 was at coal mining enterprises (79.1%), in coal mines this figure reached 90.4%, which determines the high level of occupational morbidity of miners — more than 150–200 times higher than the average in Russia2.
The study aims to conduct a comprehensive analysis of the working conditions of employees of operating coal mines in Russia according to the data of the Federal State Statistics Service in comparison with the indicators of occupational morbidity (on the example of the Rostov region).
Materials and methods. The authors have carried out the analysis of the data of the FSIS SAWC from 2018 to 2022 for all 57 coal mines operating in Russia during this period in four federal districts (FD) with a total number of jobs (RM) — 17,158, employing 60,699 people. The objects of the study were employees of 12 professions. For an integral assessment of the degree of harmfulness of working conditions of miners, we have calculated the total score of the degree of harmfulness of working conditions. Scientists investigated the occupational morbidity of miners. The experts also compared the established indicators with the data on the FSIS SAWC on the example of enterprises of the Rostov region (with the calculation of Spearman correlation coefficients).
Results. Working conditions of 13% of miners belong to Class 3.1, 42% — to class 3.2, 35% — to class 3.3 and about 2% — to class 3.4. We have identified the most unfavorable conditions in the professions of tunnellers and longwall miner (721.9 and 717.1 points) — class 3.3–3.4; drivers of electric locomotives, drivers of hoisting installations, electricians, miners (hydraulic fracturing), explosives (500.3, 495.6, 444.3, 436.4 and 407.4 points) — class 3.2–3.3; among mining foremen, fasteners, stemmers, mechanics and lifting drivers (392.9, 333.3, 261.0, 256.8, 157.1 points), class — 3.2–3.1. The leading production factors are: the severity of labor (85.1%), noise (83.3%), aerosols of predominantly fibrogenic action (79.4%). Increased levels of local vibration, unfavorable microclimate and insufficient illumination are recorded at 30–40% of the RM. The authors found that only 2.4% of workplaces exceeded the maximum permissible level (MPL) for general vibration, and 0.3% — in terms of labor intensity. There is no data on infrasound, non-ionizing and ionizing radiation.
Limitations. The study is limited to data on working conditions and occupational morbidity of coal miners for the period 2018–2022. These limitations allow us to plan further research and expand our understanding of this problem.
Conclusion. The most unfavorable working conditions we have registered in the Southern Federal District, followed by the Siberian Federal District, Northwestern Federal District, Far Eastern Federal District, which is primarily due to the technologies used and production conditions. Also, scientists have identified underestimation of the degree of harmfulness of working conditions by factors (severity and intensity of work, local vibration, light environment, microclimate), non-accounting of ionizing radiation. The structure of the leading production factors determines the modern structure of occupational morbidity of miners: radiculopathy (39.2%), respiratory diseases (36.7%), diseases from exposure to noise and local vibration (18.2%).
Ethics. The study did not require the conclusion of the Ethics Committee.

We built the relatively entire system of coal miners’ safety behavior and quantitatively analyzed Coal miners’ unsafe behavior system, then explained the path and divergence of impact factors within the system in detail. Management decision can be formulated to advance management level in coal mine industry accordingly.

The U.S. Bureau of Mines has developed preliminary recommendations for handling materials in low-seam coal mines in an effort to reduce the incidence and cost of low-back pain in underground coal mines. Three main approaches to reducing back injuries are discussed: a) research and development of task specific materials-handling hardware that would reduce the number of manual lifts in underground coal mines, b) examining the supply-handling systems currently in use at low-seam coal mines through task analysis, and c) examining the lifting capacity of low-seam coal miners in the restricted postures that must be used in underground mines. Bureau of Mines research findings and recommendations are presented and discussed.

Full textAbstract:
Objective of the research is to evaluate the probability of deterioration of the protection of miners’ respiratory organs while using filtering respirators in terms of coal mines under the coal mine conditions and to elaborate recommendations for the reduction of possible occupational disease risks. A Markovian process theory has been applied to solve the formulated problem. It has been determined that the probability of deterioration of the protection of a worker wearing a filtering respirator is up to 50%, which is stipulated by the lack of corresponding training as for the correct filtering respirator use, negligence of the physical load and its duration during the respirator selection, and possible mistakes during its operation. Reduction of the occupational disease risks is possible only in terms of the use of high-quality filtering respirator under conditions of its correct selection, maintenance and use by the trained miners with the preliminary checking of its relevance to the coal mine conditions. It has been shown that the development of a respiratory protection programme at an enterprise is the efficient tool to provide a miner with high-quality and appropriate filtering devices for the respiratory protection.

Introduction. The wide prevalence of cardiovascular diseases and their close connection with obesity, especially abdominal, makes the question of the relationship of these disorders with the respiratory system highly relevant to the coal industry. Their working conditions are closely related to the harmful effects on production factors. The study aimed to study the main cardiorespiratory parameters in coal industry workers with abdominal obesity. Materials and methods. We explored 369 men, including 225 employees of coal mines and 114 workers of open-pit coal mining enterprises in the South of Kuzbass, aged from 40 to 55 years (the average age of miners - 46.2±0.36 years, workers of open-pit mines - 46.7±0.36 years, p=0.344). Scientists conducted a study of external respiration function on an analyzer of the pneumotachometric type "Spiro-Spectrum." We used the ultrasound system "Vivid E9", manufactured by General Electric, to define echocardiographic parameters. Results. The percentage of abdominal obesity among the coal mining industry employees in the south of Kuzbass was relatively high (more than 50%). At the same time, we detected arterial hypertension much more often. Scientists have found that the average values of the lungs' vital capacity and the volume of forced exhalation for the first second have decreased in both groups in the presence of abdominal obesity. Moreover, we found a pronounced deviation among the miners. Researchers associate the values of the leading echocardiographic indicators with the presence of visceral obesity. We identified high values of systolic pressure in the pulmonary artery and characteristic signs of diastolic myocardial dysfunction in the examined patients. The researchers also identified the most pronounced indices of right and left atrial volumes in miners. In underground workers, the data of correlation analysis indirectly indicate that an increase in waist circumference is not the main factor affecting the reduction in their left ventricular longitudinal deformation. But we can't say this for onshore coal mining workers, who have a moderate connection. Conclusions. Abdominal obesity harms the respiratory system of coal industry workers, more pronounced in miners. Visceral obesity is significantly associated with dysfunction of the right and left parts of the heart, both in miners and in coal mine workers.

Occupational exposure limits for respirable coal dust are based on exposure during working hours, but coal miners may experience additional community-based exposures during nonworking hours. We analyzed Australia National Pollutant Inventory (NPI) data for the years 2008–2018 to estimate air pollutants (metals, nitrogen oxides, particulate matter ≤ 10 micrometers (PM10) and ≤2.5 micrometers (PM2.5)) originating from coal mines. PM10 levels from community-based air monitors in Queensland and New South Wales were also compared between mining and nonmining communities. Results indicated that tons of coal mined increased over the study period, and that levels of particulate matter, metals, and nitrogen oxides increased significantly over time as well. Coal mines accounted for 42.1% of national PM10 air emissions from NPI sites. PM2.5 from coal mines accounted for 19.5% of the national total, metals for 12.1%, and nitrogen oxides for 10.1%. Coal mining occurred in 57 different post codes; the 20 coal-mining post codes with the highest PM10 emissions were home to 160,037 people. Emissions of all studied pollutants were significantly higher from coal mining sites than from other types of NPI sites. Results from community-based air monitoring stations indicated significantly higher population PM10 exposure in coal mining communities than in nonmining communities. The health of the public at large is impacted by coal mining, but to the extent that miners also live near coal mining operations, their total exposure is underestimated by consideration of exposure only during working hours.

With the advancement of digital technology, the operation scenarios and work of miners have changed. Although the rate of accidents caused by unsafe conditions is decreasing year by year, the rate of accidents caused by human errors is still high. To investigate the influencing factors of miners’ human errors in the context of smart mines, based on the attitude–behavior model, this paper introduced two variables, situational awareness and task complexity, and established a moderated mediation model to explore the path of safety attitudes on human errors. Using time-lagged data from 246 full-time miners working at smart mines, we found that miners’ safety attitudes were effective in reducing human errors, miners’ safety attitudes reduced human errors through the mediation of situational awareness, and task complexity enhanced the positive relationship between safety attitudes and situational awareness, thus positively moderating the indirect relationship between safety attitudes and human errors. The findings advance a new understanding of how safety attitudes can reduce miners’ human errors. They also provide practical implications on the importance of leadership and finding ways to promote situational awareness as well as maintaining good safety attitudes.

Full textAbstract:
The study addresses the socio-economic development of the Suchan coal mine, the oldest coal-mining enterprise in the Russian Far East; it draws on archival sources in order to highlight the pages of history of the coal industry in the region. Taking into account the results of their predecessors’ work, the authors study the characteristic features of the coal industry development in the Far East under the conditions of the New Economic Policy of the Soviet state. There was a lack of diversified assistance from the Center, while the attention of the party elite to the resources of extractive industries increased: these were traditionally redirected for the needs of the Western regions or exported. The novelty consists in a comprehensive study of the development of the Suchan mine in the 1920s in the context of political and socio-economic situation in the country and the region. The study shows the role of central and local authorities at the stage of reconstruction of the coal industry, the participation of trade union organizations in the formation of labor collectives in the Suchan. It considers the mechanism of regulation of ‘collective agreement relations, the participants of which were the miner trade union and the Suchan mines. Analysis of the socio-economic development of the coal mining enterprise in the era of transformation contributes to formation of ideas about the material and living condition of the miners. The causes of unstable social situation in the Suchan mines are revealed in the context of social policy of the Soviet state. There were problems with wages and unsettled system of coal mining prices, which repeatedly became a cause for conflict between the coal hewers and the administration, attempting to avoid strikes. The social image of the Suchan workers has been reconstructed: they were mostly from rural areas and kept a close connection with the village. The unsolved housing problem had an impact on the miners’ way of life. It is concluded that with completion of the restoration of the industrial sector of the Soviet Far East economy, the model of state patronage over the region had been established; alongside with military and strategic tasks, it focused on the coal industry. However, the complex of social and household problems of the Suchan miners remained unsolved.

Abstract: The tasks involved in rescue operations in coal mines are hazardous and life-threatening. Many explosions take place from time to time, but the miners are not aware of them. It is also very difficult for the rescue squad to comprehend the situation within the mine. Hazardous gases, high temperatures, methane leaks, and low oxygen levels are examples of environmental issues. An environmental monitoring robot system for remote sensing in coal mines is introduced in this study. This robot system is designed to remotely collect information about the coal mine's surroundings, in addition to performing observational tasks. As a result, this device can be thought of as a multifunctional sensor that enables distant sensing. When it senses danger, the robot system will send out signals warning rescuers to keep their distance. Lessons from the creation of the robot system may be applied to the development of future search-and-rescue systems

Full textAbstract:
In order to seek for causes and solutions of off-post behaviors of coal miners, static and evolutionary games were utilized on the basis of an established strategy simulation model between coal mine enterprise and coal miners. These games were used to determine the revenue matrix of two game parties given off-post behaviors of coal miners from two levels (coal miners and coal mine enterprise). Thus, equilibrium and dynamic evolutionary analyses of the two parties should be conducted. Results indicated that, in the enterprise’s perspective, inspection cost and punishment intensity are important factors that influence the safety production and economic benefit of coal mine enterprises; in the coal miners’ perspective, wage loss and the constraint degree it generates are essential factors. Furthermore, these factors constitute a key to solving off-post behaviors of coal miners. Reasonability of the established simulation model was analyzed and verified on the basis of off-post behaviors of workers from a coal mine that belongs to Yanzhou Coal Mining Co., Ltd. The coal mine enterprise should enhance the inspection of safety production and establish scientific and complete off-post punishment mechanism. Moreover, the coal mine enterprise should provide proper compensation, treatment, and reward policies of workers to reduce the off-post behaviors of workers from a coal mine enterprise effectively.

IntroductionThe Rostov region was one of the largest centers of coal mining in Russia during XIX–XX centuries. The long-term effects of work in coal mines were investigated with the use of database of the Rostov regional center of occupational health.AimAssessment of mortality risks in different exposure groups of coal miners.MethodsA cohort of 9980 coal miners with established occupational diseases was formed by the Rostov regional center of occupational health. The follow-up period was 26 years (01.01.1990–31.12.2015). By the end of the follow-up period 1898 miners were alive and 8082 died. In result there were 1 38 768 person-years of follow-up. The male population of Rostov region was used as reference group.Two different exposure groups were created. First one included main professions – clearing face miners and shaft miners (5941 persons, 79 978 person-years). Maximum dust concentrations reached 270–300 mg/m3, vibration levels – 130 dB, noise levels – 130 dBA. The second one included miners of auxiliary professions (shot-firers, wiremen, loco drivers, etc.) – 4039 persons, 58 790 person-years. The maximum exposure levels were lower, 100–130 mg/m3, 110 dB, 105 dBA, respectively.ResultsThe standardized mortality ratio in the cohort (SMR) was 1.47 (CI 1.42–1.51). In the group with length of service up to 10 years, SMR=1.01 (0.91–1.13), 10–19 years SMR=1.33 (1.27–1.39), 20 years and more SMR=1.91 (1.80–2.02).In both groups the SMR was higher than in reference population. SMR=1.57 (1.50–1.63) and SMR=1.32 (1.25–1.39) respectively. The difference between subgroups was also statistically significant SMR=1.19 (1.14–1.24)ConclusionResults of follow up demonstrated elevated risks of mortality for former coal miners. A ‘dose (time) – effect’ relationship for mortality levels were also established.

Introduction. Dust is one of the main harmful factors in underground coal mining. The dust concentration in the coal mines remains high due to the imperfection of the used technologies, increasing the pneumoconiosis risk in miners. Respirators are the last means of protection, but information about their effectiveness is contradictory. Aim. Assess the effectiveness of individual respiratory protective devices in the coal mines. Material and methods. The protection factor (PF), the ratio of the dust concentration outside the mask to the concentration under the mask) is used to assess respirators’ effectiveness. We measured the PFs in the laboratory and the workplaces. We also measured the time the miners did not use respirators. The measurements’ results were used as input data for mathematical modeling to reduce dust load reduction. Results. The concentration of dust under the mask exceeded the Occupational Exposure Limit (OEL) in most cases. Information about the high efficiency of the negative pressure half-mask respirators (in case of continuous use) was not confirmed. The PFs measured under laboratory conditions reached 6.2, and in the workplace were from 5 to 31. The miners did not use respirators from 10 to 45% of the shift duration (15 measurements). The measurements and information on the concentration of dust in 5 mines were used to simulate the impact of the respirators’ usage on the dust load. Calculations performed by different methods, and using various programs, gave the same result. The negative pressure half-mask respirators cannot reduce the dust’s concentration in the inhaled air to the OEL even with continuous use. Conclusion. The results showed that the respirators’ usage could not prevent developing incurable pneumoconiosis in miners.
