· (B) Fault trace near a mine mouth in the Western Kentucky No 4 coal. Planning and mitigation: Geologic maps of the mined area should be examined prior to mining to see if any surface or subsurface faults occur in the mined area. Old mine maps in a potential mine area can also provide information as to the loion of potential faults. Major ...
· Coal mining often causes drastic changes in the soil profile and the loss of soil organic carbon and nutrient pools ( Indorante et al., 1981 ). As a direct result the soil system can suffer substantial and longlasting damage, which negatively affects land productivity and ecosystem functionality ( Hartmann et al., 2014 ).
The surface mining requirement some important equipment that also contributes to the destruction of the environment. Secondly, for the underground coal mining, the coal extraction is made by roomandpillar support procedure, with the coal being removed between the pillars, which formerly keep on supporting the roof. A minor quantity of coal

· Surface mining for coal has taken place in the Central Appalachian region of the United States for well over a century, with a notable increase since the 1970s. Researchers have quantified the ecosystem and health impacts stemming from mining, relying in part on a geospatial dataset defining surface mining's extent at a decadal interval. This dataset, .
The ILO has been dealing with labour and social problems in the mining industry since its early days, making considerable efforts to improve the work and life of miners from the adoption of the Hours of Work (Coal Mines) Convention (No. 31) in 1931 to the Safety and Health in Mines Convention (No. 176), which was adopted in 1995. Smallscale ...
