Abstract (sommario):

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

Abstract (sommario):

Coal mining in China is facing the transition from output to quality. Based on the total mining capacity and average production, the current situation of coal mining at mine, city, and province levels is analysed, and data in support for the layout of sustainable mining development and the optimization of output provided. The results show that 87% of China's coal is mined by underground methods, with an average production capacity of 0.93 Mt/a per mine. Open pit mining accounts for 13%, with an average mine production capacity of 5.73 Mt/a. The average mining capacity of coal mines in China is

Abstract (sommario):

Abstract Numerous underground coal mines were in operation in the Borsod coal basin in northeastern part of Hungary until the beginning of this century. The main area of utilization of the mined out coal beside power and heat generation was supplying households with fuel mostly for heating. In the beginning of the 1990ies the power plants in question were shut down for economic, environmental and technical reasons. Consequently all the mines were closed no later than 2004 and thousands of miners lost their jobs. A new perspective of coal mining can be enabled by other ways of utilization of co

Abstract (sommario):

Future development of mining operations along with creation of new mines, will be supported by modernization and reconstruction of existing enterprises. Creation of mechanized coal face systems that ensure complete extraction of coal reserves with the supply of occupational safety is prospective. One of the most effective technologies for the development of high coals is their mining from wall to wall with drawing coal from the roof layer into the under-cutting layer. Research of a new design of mechanized support was carried out using the developed simulation model based on the discrete eleme

Abstract (sommario):

Coal is mined by both surface and underground methods and its extraction is normally characterized by numerous hazards that can lead to catastrophic accidents, which result in devastating effects such as injuries or fatalities, damage to mining assets, and destruction of mineral resources. These hazards exist due to the ability of coal to support combustion and its association with toxic, flammable, and explosive gases. Underground coal mining entails higher safety risks than opencast coal mining, chiefly because of issues relating to mine ventilation and mine collapse. Furthermore, coal mine

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

Abstract (sommario):

The steady trend of complication of mining and geological factors in underground coal mining and at the same time the processes of mining intensification cause growth of dynamic manifestations of natural factors of mining, such as sudden coal and gas outbursts, rock bursts, rock collapses, leading to gas and dust explosions and fires. This requires developing the models of different phenomena manifestation risks, which enable improving the process safety of a mining enterprise. In this study, based on the methodology of aerological risk assessment in coal mines, a structural analysis of aerolo

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.

Abstract (sommario):

Highwall mining is a method that involves using a continuous highwall miner system (CHM) to extract coal from the remaining coal seams, which has proven to be an effective and safe method for extracting coal after open-pit mining. However, application cases globally have shown that the feasibility of highwall mining in open-pit coal mines is subject to geological conditions, mining techniques, and other factors. If application conditions are not suitable, equipment may be trapped under collapsed coal–rock masses and unable to be retrieved, resulting in severe safety issues for slope stability.

Coal is an important non-renewable source of energy, which is being constantly used by mankind for various purposes. Coal mining activities affect the surrounding ecosystem by contaminating it with traces of toxic metals, which may accumulate and affect the diversity and abundance of biological communities. A number of microorganisms, such as, filamentous fungi, yeasts and bacteria are known to degrade coal by their enzymatic action and use it as the sole source of carbon. In addition, the indoor environments of coal mines possess bioaerosols, which may include living or dead allergens, pathog

A new methodology for ranking coal mines by the integral coefficient of prospects has been developed. Unlike the known ones, the developed methodology uses a system of volumetric, technological, financial, economic, safety, environmental and social criteria for the functioning of coal industry enterprises that are accessible to the general public. These criteria have been brought to a comparable form. The methodology also takes into account the degree of importance of each criterion in terms of its impact on the technical and economic level of the mine. The system of criteria for the prospects

This paper presents changes in the functioning of hard coal mining in Poland in the period of development of free market economy, i.e. after 1989. During this period some attempts were made to bring the coal mining to remunerativeness. Five programmes of coal mining restructuring were implemented. Their main aim was the reduction of excessive production capacities. 23 coal mains were closed down in the period 1989–2003, especially in the northern and eastern parts of the coal basin, which include the areas where coal exploitation was the longest and coal resources are located under considerabl

Hazardous and ineffective mines were closed, and a number of underground and strip mines of a modern technological level were built as a result of the restructuring of the coal industry in Russia. However, safety in the coal mines continues to be one of the urgent issues nowadays. In underground coal mining, the main types of risks are processes occurring in the rock mass as a result of mining operations. It is necessary to realize timeous and the most accurate prediction of harmful events, which occur during a development of coal fields, to increase the efficiency and reduce the cost of coal

In Poland, apart from opencast mining, brown coal (lignite) was also mined by underground methods. This is related to glaciotectonic disturbances leading to deposition of Miocene coal in the form of folds (synclines and anticlines). The highest number of underground brown coal mines in the 19th century was recorded in western Poland. In northern Poland in the second half of the 19th century there were active underground brown coal mines in Piła Młyn.
