The results show that contaminants are released after selfignition and weathering of coal mining wastes, but they are not above the allowable environmental standards. However, despite these findings, more and closer attention needs to be paid to the mobility, transportation and accumulation of these contaminants in the environment over time.

Mar 14, 2012· Environmental Consequences of Open Pit Mining An open pit mine is a type of excavation where surface and subsurface materials (soil and rock) are removed, typically through use of explosives and mechanical mining and hauling equipment, to gain access to commercially valuable ores or other buried natural resources, including coal and gemstones, that are relatively close to the surface.

By nature, mining involves the production of large quantities of waste, in some cases contributing significantly to a nation's total waste output. For example, a large proportion of the materials flows inputs and outputs in the United States can be attributed to fossil fuels, coal, and metal mining (Matthews et al., 2000:107). The amount of waste

Surface mining at these scales is more economical for coal companies, safer for miners, and, coal operators say, essential for mining the thin seams of lowersulfur coal more valuable in today's market. With dynamite and immense machines, surface mines can produce more than two to three times as much coal per miner as underground mines can.
