Abstract:
En este trabajo se analiza la gestación de la normativa de protección ambiental relacionada con las actividades mineras, así como disposiciones específicas mineras que se fueron aprobando y tuvieron incidencia para reducir los efectos negativos al medio natural. Las normativas mineras que se aprobaron en la Edad Moderna preveían algunas medidas a fin de evitar perjuicios a la agricultura, ganado y a pueblos en el entorno de actividades mineras. En el siglo XIX, con un Estado liberal, se fueron aprobando lentamente a partir de mitad de siglo diversas leyes y reglamentos mineros, debido a conflictos sociales, que introdujeron medidas con efectos de protección a la salud y al medio natural. Con un mayor grado de intervencionismo estatal en el siglo XX se fueron aprobando, en un contexto de presión de grupos sociales afectados, diversas normas sectoriales de protección a ríos y arroyos. La Ley de Minas vigente introdujo que se aprobase por decreto el fijar las condiciones imperativas de protección del ambiente, siendo el origen del primer Real Decreto de restauración de actividades mineras de 1982. This paper analyzes the gestation of environmental protec-tion regulations related to mining activities, as well as specific mining provisions that were approved and had an impact to reduce the negative effects to the natural environment. The mining regulations that were approved in the Modern Age envisaged some measures in order to avoid damage to agri-culture, livestock and to villages in the environment of mining activities. In the XIX century, with a liberal State, several laws and mining regulations were slowly being adopted from the middle of the century, due to social conflicts, which introduced measures with health and natural protection effects. With a greater de-gree of state interventionism in the XX century, in a context of pressure from affected social groups, various sectoral rules for the protection of rivers and streams were approved. The Law of Mines in force introduced that it was approved by decree to fix the imperative conditions of protection of the environ-ment, being the origin of the first Royal Decree of restoration of mining activities of 1982.

Abstract:
Las cooperativas conforman una experiencia centenaria del agro argentino. En el siglo XXI, su desarrollo es uno de los principales ejes del Plan Estratégico Agroalimentario y Agroindustrial Participativo y Federal 2010-2020 para el logro de objetivos de competitividad y equidad social. Desde sus orígenes, el cooperativismo agrario procura cumplir con un doble objetivo: el primero, de carácter social, está destinado a la prestación de un servicio basado en principios de solidaridad, libre asociación y gestión democrática; el segundo, de carácter económico, está orientado a defender los intereses y mejorar la situación económica de sus asociados.Desde un criterio funcional, las cooperativas agrarias pueden cubrir diversas actividades, necesidades o servicios, tales como el aprovisionamiento, la producción, comercialización, la transformación o industrialización y el crédito, cumpliendo una o varias de esas fases. El artículo procura mostrar las transformaciones y permanencias operadas en el modelo cooperativo, a través del análisis de dos asociaciones emblemáticas del agro argentino: por un lado, la Asociación de Cooperativas Argentinas (ACA), primera entidad de segundo grado constituida en 1922 y que en la actualidad se encuentra entre los principales exportadores de cereales. Por otro, Agricultores Federados Argentinos (AFA), conformada en 1932 y que hoy es la principal cooperativa de primer grado del país. This paper analyzes the gestation of environmental protec-tion regulations related to mining activities, as well as specific mining provisions that were approved and had an impact to reduce the negative effects to the natural environment.

Abstract:
In today's economy, it is necessary to explore the environmental impact of mining. Coal mining greatly affects all environmental parameters of the environment: home, production, hydrodynamics. The environmental situation in the area of the mining company can be changed if environmental contamination is monitored and environmental protection plans and measures are developed. The purpose of this work is the analysis of systems and models of these processes in the ecosystem. The main systemic hypothesis of the research is that the variety of criteria and methods of risk assessment is a necessary condition of order in the system. The main results of the work are the following: 1) a systematic analysis of the problems of environmental security, geodynamics of the mining areas, aspects of the balance of the sustainable process and the cause of the increase in danger was carried out; 2) Proposed approaches (models) for the assessment of evolutionary ecological potential and health risks, as well as adaptive situational modeling of the ecosystem. It is important to note, the study results do not suggest complex environmental monitoring studies.

Abstract: The objective of this work was to evaluate the soil mesofauna composition in non-mining and in mining areas under environmental recovery with native vegetation and forest planting, in a coalmine in Southern Brazil. Five treatments were evaluated: native vegetation in non-mining area; plantation of Acacia mearnsii in non-mining area; plantation of A. mearnsii in mining area; plantation of Eucalyptus dunnii in non-mining area; and plantation of E. dunnii in mining area. Four soil samples per treatment were collected monthly, during one year. The organisms were extracted using a Berlese funnel with 50-W incandescent light. A total of 23,911 organisms were collected from the soil mesofauna, which were identified and distributed into 13 taxonomic groups. The abundance of specimens was similar between treatments. The greatest diversity of taxonomic groups was found under A. mearnsii plantation, in the mining area, and under E. dunnii plantations in non-mining and mining areas, all with 13 groups. Eucalyptus dunnii and A. mearnsii help to mitigate the impact of coal mining on the diversity of the soil mesofauna taxonomic groups, since the composition of mesoarthropods is similar to that of areas that have not been directly affected by mining.

Abstract:
The paper presents the results of a drinking water quality study in towns located in the mining areas of the Republic of Bashkortostan, The Russian Federation. The objects of the study were underground water supply sources and water distribution networks of the towns of Uchaly, Sibay, and Baimak. In total, 30 water wells were examined, and five water samples were collected from the water distribution network in each town. The water quality indicators were pH, solid residue, total hardness, copper content, zinc content, iron content, and manganese content. The water quality in water distribution networks corresponded to the permissible limits according to environmental and sanitary regulations, except for the increased iron contentprobably due to corrosion of water supply pipelines. The water quality in non-centralized water supply (wells) in some areas failed to meet the sanitary standards. Priority indicators of water pollution were increased hardness and mineralization, high content of iron and manganese. To provide the residents with high-quality drinking water, it is proposed to make a complete inspection of centralized and non-centralized water sources not only within the towns, but also in the neighbouring communities. It is necessary to install filtration plants, primarily to reduce the iron content, in roder to bring the water taken from the wells for household and drinking purposes to the standard quality.

Abstract:
The aim of the research is to cast light on the legal regime of the mining area land in medieval Serbia and to answer to what extent Saxon customary mining law was accepted in this aspect and what the ratio legis of article 123 of Dušan's Code was? It seems likely that until the enactment of Dušan's Code it was possible to occupy land cleared for mining purposes and to acquire property of the mining area, which was previously res nullius. However, Dušan's Code changed this rule prescribing only the possibility of acquiring the time limited mining concession, which was motived by possible permanent monopolization of the land in the mining areas. At the same time, the Code proclaimed the right of ore search and exploration on the feudal lords' land. Similarities to the older Hungarian and Czech law indicates legal transplantation. The mining concession was regulated in Despot Stefan's Mining Code for Novo Brdo, which prescribed detailed rules for losing the concession in the case of neglecting the mining activity. Based on similarities one can assume that these rules were mostly the reception of the Saxon customary mining law, also written in late medieval mining laws of Hungary and Czechia. However, the small differences may show that after one and a half century the Serbian mining community introduced its own unique rules. Research is based on linguistic, systematic and historical analysis of the sources as well as the regressive analysis and comparative method.

Abstract:
In the Czech Republic, industrial areas, mining areas and military zones can be found. These areas represent potential risks for the agricultural production from the viewpoint of hygienic standards. The industrial areas and mining areas are the topic of the present study. The industrial areas are combined with present or past mining activities in the Czech Republic in most cases. The widest industrial areas located in North-Bohemian and North-Moravian regions were based on the mining of brown and black coal. North-Bohemian region was affected by the combustion of brown coal in the power stations during many years and the region was a part of the Middle-European area called black triangle. The problems with increased contents of risky elements (mainly As from brown coal combustion) and persistent organic pollutants in the soil are documented. North-Moravian region with the mining of black coal is typical with its industrial metallurgical activities. Increased contents of Cd and persistent organic pollutants-POPs (mainly polycyclic aromatic hydrocarbons-PAHs and dibenzo-p-dioxines and dibenzofurans-PCDD/F) in the soils of the region are a topical problem. In addition to this fact, mainly native soil owners use the soil for husbandry (gardens, crofts). The contents of risky elements and POPs (including PCDD/F) in selected soil samples from the area are documented. Next area of a similar kind is represented by the Příbram district where the mining and treatment of the ores has been under way since Middle Ages. The serious contamination of the agricultural soils by Pb, Cd, and Zn was and still is being solved by research projects. The contamination of the soil by As in the Kutná Hora district represents a typical past mining load caused by the spread of mining wastes on the soils in the vicinity of the medieval mining town Kutná Hora. The last type of the increased soil load presented is connected with fluvial zones of some rivers. The floods by contaminated water were the source of the soil contamination.

<p><strong>Abstrak</strong>. Lahan bekas tambang timah berpeluang untuk dimanfaatkan sebagai areal pertanian dalam upaya pemenuhan kebutuhan pangan dan mengatasi persoalan lingkungan pasca penambangan. Tujuan makalah ini adalah untuk mengkaji upaya reklamasi lahan bekas tambang timah untuk dijadikan areal pertanian di Kepulauan Bangka Belitung. Luas seluruh izin usaha penambangan (IUP) yang telah diterbitkan oleh pemerintah pusat dan daerah dan dimiliki oleh perseroan di darat sebesar 327.524 ha, sedangkan luas IUP di laut 183.837 ha. Aspek biofisik lahan sangat menentukan keberhasilan reklamasi lahan bekas tambang timah. Pemanfaatan lahan bekas tambang timah sebagai areal pertanian menemui sejumlah kendala biofisik lahan, seperti bentang lahan (lanskap) yang tidak beraturan, hilangnya lapisan atas tanah (top soil), rendahnya status kesuburan tanah, dan terganggunya kualitas air kolong. Selain aspek biofisik, upaya reklamasi juga patut mempertimbangkan aspek sosial ekonomi, seperti status kepemilikan lahan, pengetahuan dan keterampilan petani, dan kelayakan biaya usaha tani. Penyimpanan tanah pucuk, penataan lahan, penggunaan amelioran, pengembangan Legume Cover Crops, implementasi Integrated Farming Systems, dan perbaikan kualitas air kolong di lahan bekas tambang timah diyakini mampu meningkatkan kualitas dan daya dukung lahan bekas tambang timah untuk areal pertanian. Reklamasi lahan bekas tambang timah juga membutuhkan partisipasi aktif masyarakat, pemerintah daerah, dan perusahaan tambang timah. Kegiatan reklamasi yang mampu memberikan manfaat bagi masyarakat setempat untuk berusaha tani di lahan bekas tambang timah dapat dijadikan sebagai salah satu indikator keberhasilan reklamasi pasca penambangan.</p><p><strong>Abstract</strong>. Abandoned tin-mining lands have the potential to be used as agricultural areas in order to fulfill food demand and solve the environmental problems derived from mining activities. The purpose of this paper is to assess the reclamation measures on abandoned-tin mining areas which could be used as agricultural areas in Bangka Belitung Islands. The total areas of the mining business license (IUP) issued by the central and local government and owned by the company are 327,524 ha in inland and 183,837 ha in the sea. Biophysical aspects largely determines the success of reclamation of abandoned tin-mining areas. Utilization of abandoned-tin mining areas as agricultural areas is facing land biophysical constraints, such as undulating landscape, losses of top soil, low soil fertility status, and disruption of water quality of tin-mining pond. In addition to the biophysical aspects, reclamation efforts should also consider the socio-economic aspects, including land ownership status, knowledge and skills of farmers, and the feasibility of the cost of farming systems. Conservation of top soil, arrangement of land, development of legume cover crops, implementation of Integrated Farming Systems, and improvement of water quality in the area under the former tin mine are believed to improve the quality and carrying capacity of abandoned tin-mining areas to be used as agricultural areas. Reclamation of abandoned tin-mining areas also requires the active participation of the community, local government, and tin mining company. Reclamation activities that can provide benefits to local communities for farming in tin mined land can be used as one indicator of the success of the post-mining reclamation.</p>

Abstract:
Abstract The new basic safety standards (BSS) Directive 2013/59/Euratom [1] puts EU member states under an obligation to establish, amongst others, national radon action plans. In order to address the issue of long-term risks from radon exposures, it is important to identify areas where elevated levels of radon can be expected. One of the types of areas affected by an increased migration of radon and by the penetration of radon into buildings are areas in which industrial activity, for example, the exploitation of mineral resources, causes changes in the geological environment. The Upper Silesian Coal Basin (USCB) in Poland is one of the examples. The results of studies conducted in the past have shown that the levels of indoor concentration of radon, to a large extent, depend on the geological structure of the subsurface layers. One of the main factors influencing the migratory abilities of radon are the mining-induced changes of a rock body. We estimate that in specific radon-prone zones, the levels of radon may exceed 300 Bq/m3 in approximately 2% of the dwellings. Another problem that may appear in post-mining areas is linked to the reclamation of radioactively contaminated areas. The complex geology of the strata in USCB, the mining activity that can be observed in the region and, additionally, the discharge of radium-bearing waters into the environment are the most significant factors affecting radon potential and hazard in dwellings in this region. In this paper, problems linked to the detection of radon in the mining area of USCB are presented.

Abstract:
Mining can provide necessary mineral resources for humans. However, mining activities may cause damage to the surrounding ecology and environment. Vegetation change analysis is a key tool for evaluating damage to ecology and the environment. Liaoning is one of the major mining provinces in China, with rich mineral resources and long-term, high-intensity mining activities. Taking Liaoning Province as an example, vegetation change in six mining areas was investigated using multisource remote sensing data to evaluate ecological and environmental changes. Based on MODIS NDVI series data from 2000 to 2019, change trends of vegetation were evaluated using linear regression. According to the results, there are large highly degraded vegetation areas in the Anshan, Benxi, and Yingkou mining areas, which indicates that mining activities have seriously damaged the vegetation in these areas. In contrast, there are considerable areas with improved vegetation in the Anshan, Fushun, and Fuxin mining areas, which indicates that ecological reclamation has played a positive role in these areas. Based on Sentinel-2A data, leaf chlorophyll content was inferred by using the vegetation index MERIS Terrestrial Chlorophyll Index (MTCI) after measurement of leaf spectra and chlorophyll content were carried out on the ground to validate the performance of MTCI. According to the results, the leaf chlorophyll content in the mines is generally lower than in adjacent areas in these mining areas with individual differences. In the Yingkou mining area, the chlorophyll content in adjacent areas is close to the magnesite mines, which means the spillover effect of environmental pollution in mines should be considerable. In the Anshan, Benxi, and Diaobingshan mining areas, the environmental stress on adjacent areas is slight. All in all, iron and magnesite open-pit mines should be monitored closely for vegetation destruction and stress due to the high intensity of mining activities and serious pollution. In contrast, the disturbance to vegetation is limited in resource-exhausted open-pit coal mines and underground coal mines. It is suggested that land reclamation should be enhanced to improve the vegetation in active open-pit mining areas, such as the Anshan, Benxi, and Yingkou mining areas. Additionally, environmental protection measures should be enhanced to relieve vegetation stress in the Yingkou mining area.

Abstract:
Although mining plays an important role for the economy of the Amazon, little is known about its attributes such as area, type, scale, and current status as well as socio/environmental impacts. Therefore, we first propose a low time-consuming and high detection accuracy method for mapping the current mining areas within 13 regions of the Brazilian Amazon using Sentinel-2 images. Then, integrating the maps in a GIS (Geography Information System) environment, mining attributes for each region were further assessed with the aid of the DNPM (National Department for Mineral Production) database. Detection of the mining area was conducted in five main steps. (a) MSI (MultiSpectral Instrument)/Sentinel-2A (S2A) image selection; (b) definition of land-use classes and training samples; (c) supervised classification; (d) vector editing for quality control; and (e) validation with high-resolution RapidEye images (Kappa = 0.70). Mining areas derived from validated S2A classification totals 1084.7 km2 in the regions analyzed. Small-scale mining comprises up to 64% of total mining area detected comprises mostly gold (617.8 km2), followed by tin mining (73.0 km2). The remaining 36% is comprised by industrial mining such as iron (47.8), copper (55.5) and manganese (8.9 km2) in Carajás, bauxite in Trombetas (78.4) and Rio Capim (48.5 km2). Given recent events of mining impacts, the large extension of mining areas detected raises a concern regarding its socio-environmental impacts for the Amazonian ecosystems and for local communities.

Abstract:
In recent years, mounting attention has been paid to ecological environmental management in coal mining areas in China. This paper conducts a system dynamics (SD) model for ecological environmental management in coal mining areas. Firstly, the whole causal loop diagram of the system is built to illustrate the general system. Secondly, five subsystems are presented according to the causal loop diagram. Then, given the stable investment for ecological environmental management in coal mining areas, our objective is to find a better allocation that can get the best ecological environmental quality in coal mining areas. Notably, we present six allocations of the investment for ecological environmental management in coal mining areas. The results show that, in allocation 4, we can get the best ecological environmental quality in coal mining areas. That is, the best improvement of mining environment can be achieved by distributing the treatment cost highly on the proportion of investment in green vegetation.

Abstract:
Based on the results of an extensive literature research, we summarize the research progress of remote sensing monitoring in terms of identifying mining area boundaries and monitoring land use or land cover changes of mining areas. We also analyze the application of remote sensing in monitoring the biodiversity, landscape structure, vegetation change, soil environment, surface runoff conditions, and the atmospheric environment in mining areas and predict the prospects of remote sensing in monitoring the ecological environment in mining areas. Based on the results, the accurate classification of land use or land cover and the accurate extraction of environmental factors are the basis for remote sensing monitoring of the ecological environment in mining areas. In terms of the extraction of ecological factors, vegetation extraction is relatively advanced in contrast to the extraction of animal and microbial data. For the monitoring of environmental conditions of mining areas, sophisticated methods are available to identify pollution levels of vegetation and to accurately monitor soil quality. However, the methods for water and air pollution monitoring in mining areas still need to be improved. These limitations considerably impede the application of remote sensing monitoring in mining areas. The solving of these problems depends on the progress of multi-source remote sensing data and stereoscopic monitoring techniques.

Abstract:
Gold mining comes with several benefits to developing countries, manifested mainly in the form of employment and revenue, but simultaneously impacts negatively on the immediate environment. It affects the economic structure including agriculture and its productivity. Hence, this study investigated the effect of gold mining on total factor productivity of farmers in Ghana using 110 cocoa farmers from Asutifi North and Asutifi South districts of the Brong Ahafo Region, categorised into mining and non-mining areas respectively. About 83 % of the farmers in the mining areas were affected by gold mining through channels such as land disputes, relocation of farm/residence, high cost of labour, illegal small-scale mining and dust settlement on crops. Also, about 64 % of cocoa farmers in the mining areas lost their farm lands (between 0.4 and 3.64 ha as a result of gold mining. The Tornqvist Total Factor Productivity (TFP) indices for cocoa farmers in the non-mining areas (mean TFP of 1.404) were also statistically higher than those in the mining areas (mean TFP of 0.371). The study concluded that gold mining activities adversely affect productivity of farmers in the catchment areas. The study recommends, among others, that a policy of land-for-land should be in place and effectively implemented to ensure that mining companies in order to enhance and ensure continuity of livelihoods must fully replace lands lost through mining activities.

Abstract:
Australia leads the world in formally dedicating private land to environmental conservation, helping governments protect critical biodiversity without straining the public purse. In Queensland, the booming resources sector threatens this biodiversity protection, even beyond landholders’ well-recognised lack of veto power over mining approvals on their land. Three structural legal biases increase this vulnerability. To differing degrees, Queensland’s laws assume that mining affects only land under or adjoining mining tenures, overlooking scientifically likely longer-distance impacts (‘boundary bias’); they emphasise protecting built and commercial infrastructure over ecological assets, overlooking significant investment in species and ecosystems (‘infrastructure bias’); and they allow consideration of proposed mining in isolation, without considering cumulative impacts on ecological assets (‘singularity bias’). Fortunately, Queensland law and policy precedents suggest potential corrective reforms.

Abstract:
Land reclamation plays a vital role in the ecological improvement and economic development of mining regions. This study aims to conduct a preliminary discussion on the evaluation content, evaluation methods, and evaluation indicators of land reclamation benefits in mining areas. Using fuzzy comprehensive evaluation (FCE) method, land reclamation was assessed. After compiling a model of the land reclamation influencing factors, an evaluation index of land reclamation benefit in the mining area was constructed using the land reclamation monitoring data for the northern part of the mining area over the last decade. In addition, an expert scoring method and a traditional evaluation model were used to estimate the comprehensive benefits of land reclamation at Hanjiawan coal mine in Shendong mining area. Land reclamation markedly improved the land type within the mining region and decreased the amount of damaged land, including subsided and occupied land. Moreover, land reclamation improved the available land area such as agricultural and construction land. The proposed model obtained an overall 63% increase in the land reclamation area. Different degrees of ecological, economic, and social benefits of Hanjiawan coal mine were observed; however, the ecological benefits were the most significant, with a growth rate of 56%. Based on the evaluation criteria, all benefits of the mining area after reclamation were good. Over time, land reclamation will offer greater comprehensive benefits to the mining area. Furthermore, this method can be used for precise evaluation of comprehensive benefits after land reclamation, and the assessment results will provide a reference basis for sustainable development of the mining area.

Abstract:
Vegetation in eastern Inner Mongolia grasslands plays an important role in preventing desertification, but mineral exploration has negative effects on the vegetation of these regions. In this study, the changing trend types of vegetation in eastern Inner Mongolia were analyzed using the normalized difference vegetation index (NDVI) time series from the Global Inventory Modeling and Mapping Studies (GIMMS) NDVI 3g dataset from 1982 to 2015. Meanwhile, changing trend and influencing factors of 25 large-scale mining areas before and after mining were explored with the methods of trend line, residual calculation, and correlation analysis. The vegetation coverage towards increasing in eastern Inner Mongolia decreased in the order of Tongliao > Hinggan League > Chifeng > Hulunbuir > Xilingol over the past 34 years. Vegetation showed a decreasing tendency in 40% mining areas, but an increasing tendency in 60% mining areas after mining. Vegetation change in Shengli No. 1 had a significant correlation with precipitation and human activities after mining. Except Shengli No. 1, an obvious correlation was found between vegetation change and precipitation in 45.83% mining areas after mining. Human activities had significant positive effects on vegetation growth in 25% mining areas. Significant negative effects of human activities were found in 8.34% mining areas, causing the vegetation degradation. However, there were 20.83% mining areas with vegetation changes not affected by precipitation and human activities.

Abstract:
The Lusatian lignite-mining district (Eastern Germany) is characterized by a high share of marginal post-mining areas. At these sites, crop yield is generally low, and hence, conventional land use systems often fail in terms of reliable and efficient crop production. In this paper the attempt is made to evaluate the production of woody biomass for bioenergy in short rotation coppices (SRC) and alley cropping systems (ACS) with black locust (Robinia pseudoacacia L.) and lucerne (Medicago sativa L.) from the aspect of possible ecological and economic benefits compared to the conventional agricultural recultivation practice. The results show that, due to both high establishment and harvesting costs and comparatively low prices of energy wood, land use systems such as SRC or ACS are currently hardly profitable compared to conventional agriculture. However, the cultivation of black locust resulted in a higher humus accumulation and in a lower harvest-related nutrient export than the cultivation of lucerne as a typical recultivation crop in this region. Therefore, it can be concluded that for an improvement of soil fertility woody biomass production is more beneficial than the conventional agricultural recultivation practice.

Abstract:
Mining activities are among the most long-lasting anthropogenic pressures on streams and rivers. Therefore, detecting different benthic macroinvertebrate assemblages in the areas recovered from mining activities is essential to establish conservation and management plans for improving the freshwater biodiversity in streams located near mining areas. We compared the stability of benthic macroinvertebrate communities between streams affected by mining activities (Hwangjicheon: NHJ and Cheolamcheon: NCA) and the least disturbed stream (Songjeonricheon: NSJ) using network analysis, self-organizing map, and indicator species analysis. Species richness was lowest at sites where stream sediments were reddened or whitened due to mining impacts in NHJ and NCA. Among functional feeding groups, the ratio of scrapers was lower (i.e., NHJ) or not observed (i.e., NCA) in the affected sites by mining. The networks (species interactions) were less connected in NHJ and NCA than in NSJ, indicating that community stability decreased in the area affected by mining activity. We identified five groups based on the similarity of benthic macroinvertebrate communities according to the gradients of mining impacts using a self-organizing map. the samples from the reference stream (clusters 1 and 5), sites located near the mining water inflow area (cluster 4), sites where stream sediments acid-sulfated (cluster 2), and sites that had recovered from mining impacts (cluster 3). Among the 40 taxa selected as indicators defined from the five clusters in self-organizing map, only few (Physa acuta, Tipula KUa, and Nemoura KUb) indicator species were selected in each cluster representing the mining-impacted sites. Our results highlighted that the benthic macroinvertebrate community complexity was lower in streams affected by mining activity. Furthermore, the range of disturbed areas in the streams, where conservation and management plans should be prioritized, can be quantified by examining alterations in the benthic macroinvertebrate community.

Abstract:
Aggregated mining development has direct and indirect impacts on vegetation changes. This impact shows spatial differences due to the complex influence of multiple mines, which is a common issue in resource regions. To estimate the spatial heterogeneity of vegetation response to mining activities, we coupled vegetation changes and mining development through a geographically weighted regression (GWR) model for three cumulative periods between 1999 and 2018 in integrated resource regions of northwestern China. Vegetation changes were monitored by Sen’s slope and the Mann–Kendall test according to a total of 72 Landsat images. Spatial distribution of mining development was quantified, due to four land-use maps in 2000, 2005, 2010, and 2017. The results showed that 80% of vegetation in the study area experienced different degrees of degradation, more serious in the overlapping areas of multiple mines and mining areas. The scope of influence for single mines on vegetation shrunk by about 48%, and the mean coefficients increased by 20%, closer to mining areas. The scope of influence for multiple mines on vegetation gradually expanded to 86% from the outer edge to the inner overlapping areas of mining areas, where the mean coefficients increased by 92%. The correlation between elevation and vegetation changes varied according to the average elevation of the total mining areas. Ultimately, the available ecological remediation should be systematically considered for local conditions and mining consequences.

Abstract:
Sustainable development policy emphasizes, among other things, the role of green areas in urban space. This remark applies in particular to post-industrial and post-mining cities. One of the elements of shaping the sustainable development of post-mining cities is that forests are often anthropogenic forest ecosystems growing in previously mining areas, one of the most characteristic elements of their spatial development. This article examines the role of urban forests in the post-mining area in Sosnowiec, located in the core of the Katowice conurbation in southern Poland. This article aimed to show the social perception of forests in post-mining areas among the local community and the features of urban forests. The social dimension of the interaction between humans and the environment is related to the issue of urban planning. Research was implemented based on quantitative, qualitative (CATI survey), and cartographic methods. The results indicate the significant role of forests in post-mining areas depending on their location in the settlement areas in a post-industrial city. The research emphasizes that residents perceive forests in post-mining areas of cities as an essential and expected recreational space. Notably, half of them do not see any threats therein. It is also expected that these areas will be better developed for recreational purposes in the future.

Abstract:
Introduction: Placenta morphometry varies with increased heavy metal concentrations among other factors. There is limited knowledge on the effect of perceived heavy metal exposure due to mining activities on placenta morphometry specific to the Tanzanian population. The study thus aimed to determine the morphometric characteristics of the human placenta and the association between placental weight with maternal factors in mining and non-mining areas in Northwestern Tanzania. Subjects and Methods: This was a comparative cross-sectional study conducted in Mwanza and Geita regions of Northwestern Tanzania representing the mining and non-mining areas, respectively. Included in the study were placentas from 490 mothers, residing in the respective areas throughout pregnancy. Comparison of the placenta morphometric variables between the two groups was made using the independent sample t-test, and association between the maternal factors and placenta weight was done using multi-level linear analysis. Results: The mean placenta weight in the non-mining and mining areas was 465.9±101.2 g and 443.6±82.7g, and the mean thickness was 1.52±0.32cm and 1.61±0.38cm respectively. The mean diameter in the non-mining and mining areas was 19.0±1.9cm, the mean cotyledon number was 20±5 and 19±4, and the mean cord length was 49.0±12.7cm and 50.1 ±10.4cm respectively. With the exception of cord length, the differences in the morphometric parameters in the non-mining and mining areas were significant p<0.5. Increase in maternal weight on booking and maternal age were associated with corresponding increase in placenta weight. Conclusion: The findings of this study seem to suggest that heavy metal exposure due to mining activities does affect placenta growth.

Abstract:
Slope structures and surface terrains are two significant factors affecting the deformation behavior of mining slopes in mountainous areas. This research is aimed at investigating the deformation characteristics of a mining slope wielding Particle Flow Code (PFC), with 9 different mining configurations (i.e., horizontal distance from extracted panel center to slope shoulder, D = −200 m, −150 m, −100 m, −50 m, 0 m, 50 m, 100 m, 150 m, and 200 m). A representative slope in Faer Town, Liupanshui City, Guizhou Province, China, was selected, which was characterized by soft and hard interbedded rock strata. The results indicated that the overlying rock mass tended to move towards the sloping surface with mining beneath sloping terrain, which brought an asymmetrical subsidence funnel, and formed a wider relative disturbance range on the slope surface. With the vertical subsidence increasing additionally, the stability of the overall slope deteriorated. A safe mining range should be proposed based on evaluating the time-dependent deformation behavior at the slope shoulder and the overall slope stability.

Abstract:
Along with the accelerated shift of coal mining to the ecologically fragile west, the contradiction between coal resource development and ecological protection in the western arid and semiarid coal mining areas is rapidly intensifying. Based on the above background, this thesis takes the coal mining area in the arid and semiarid regions as an example; applies the theories of ecology, coal mining subsidence, geodesy, and ecological restoration; uses remote sensing in synthetic aperture radar (SAR), geographic information system (GIS), and mathematical modelling to reveal the ecological evolution law of the mining area; measures the ecological damage of the mining area; and then proposes a reasonable ecological restoration strategy. The surface deformation monitoring study in the study area shows that on the whole, some areas in the study area have different degrees of surface subsidence disasters, and the maximum surface subsidence value exceeds 800 mm. From the distribution of surface subsidence in the study area, surface subsidence disasters mainly occur in the eastern and central mountainous areas rich in coal resources, as well as in the mining areas west of the Yellow River, and the subsidence basins are distributed in a series of irregular concentric ovals. In terms of the scale of surface subsidence in the study area, a total of 230.03 km2 of land in the study area showed surface subsidence hazards during the monitoring period, accounting for 13.78% of the total area of the study area, of which the area of severe subsidence was 44.98 km2 (2.69%). The area of more serious subsidence area is 101.33 km2 (6.07%), and the area affected by subsidence is 83.72 km2 (5.01%).
