This case study focuses on the costs of the environmental and social effects of coal mining in South Africa, undertaken for export to the Netherlands. Coal mining imposes many external costs on its surroundings and the people who live in it. Some of these can be quantified by estimates, others are difficult to estimate. Coal mining is
— To study the impact of surface coal mining activities in a part of JCF, a multi-temporal analysis of Landsat (TM and OLI/TIRS) data has been undertaken for the years between 2006 and 2016.

The finite element method, physical simulation and field monitoring were applied to analyze the mining-induced strata failure and hydraulic …
— Karnataka High Court had quashed the Lokayukta criminal proceedings in 2011 and had cleared Kumaraswamy in the Janathakal mining case. Last year in September, the Supreme Court ordered Kumaraswamy to face trial in the 2007 Janthakal case. Lokayukta Special Investigation Team arrested Vinod Goel, owner of Janathakal …
— The case study (PEKB mine) was conducted in the mining areas of Parsa East Kanta Basan blocks in villages like Salhi, Hariharpur, Parsa, Kente, Ghatbarra, Parogiya and Basan in Udaipur tehsil, Surguja district, Chhattisgarh. The paper dwells upon various activities proactively undertaken at the mine towards in course of its usual …
— The coal seam in the southern coal field of the Ordos Basin serves as the main aquifer, while the region is known for its high-intensity coal mining activities. The coupling effect of mine water and the strong disturbance caused by high-intensity mining have brought serious challenges to the stability of coal pillars. To address this, a formula …
— China has the largest coal production in the world due to abundant resource requirements for economic development. In recent years, the proportion of opencast coal mine production has increased significantly in China. Opencast coal mining can lead to a large number of environmental problems, including air pollution, water pollution, and …

— Firstly, taking Jharia coal-fi eld as a case study, the parameters/criteria affecting the environment have been identi fi ed. The parameters that are the most affected due to mining are air,
— The coal seam inclination is 25° on average. As shown in Fig. 1 (b), the longwall panel was excavated along an apparent dip angle of approximately 8° to 10°. The cover depth of the panel is approximately 760 m to 900 m. The mining depth of the cross point of the fault and coal seam is approximately 850 m.
— The JCM underground fire was ignited in 1916 by an unidentified factor (BCCL, 2008) and has never extinguished in spite of huge efforts by the Indian government and local authorities.Since the first coal fire was detected in 1916, collapse due to underground fire has caused extensive subsidence and fissures that act as the suppling …
— The elevation of the A7 coal seam outcrop is 1400 m, 20 ~ 25 m from A9. The thickness of coal seams A7 and A9 is approximately 2 m. The thickness of coal seams A10 and A11 is less than 0.8 m, and the spacing between two layers is small. After nearly 40 years of mining in five coal mines, the extent of coal seam mining has reached 200 m.
In this compendium of over fifty case studies, the coal industry demonstrates that practical progress is being made in many areas: communities and people; resource stewardship and environmental impacts; management processes and systems; and along the value chain, in co-operation with customers and suppliers.

— In Xinjiang Uygur, China, grass is the main plant type, ranging from tall grasslands to short grasslands in deserts. The ecological environment is extremely fragile in this area (Zuo et al., 2021a, 2021b).Underground coal mining can lead to overlying strata movements, which ultimately cause surface subsidence (Peng, 1992).The prediction …
With further exploitation, the whole Coalfield was evolved into moderate and heavy ecological vulnerability area, and the coal resources mining was a key factor in this process. The cluster analysis showed that the spatial distribution of the ecological vulnerability in the study area had reasonable clustering characteristics.
