12 Environmental Effects of Coal Mining

12 Environmental Effects of Coal Mining

There is much debate whether the environmental effects of coal mining justify its continued use. Coal is either extracted from deep inside the earth or removed from its surface. The former is known as underground mining, the latter as strip mining or mountaintop removal. Either process contributes a high level of damage to the environment:

Surface mining of coal is characterized by the use of large, capitalintensive and efficient mining equipment. First, the overlying soil and rock layers (overburden) are removed. The coal is then fractured with explosives or machines, and loaded onto vehicles for haulage from the mine site.

 · Surface coal mining involves: removing parts or all of mountaintops to expose buried seams of coal, and. "interburden" (rock between coal seams). Overburden and interburden are disposed of in adjacent valleys because the broken rock will not all fit back into the mining pit, and disposal alternatives are limited.

Equipment Selection for Surface Mining: A Review

A surface mine contains pits with mineral endowed rock (or ore). We extract ore that lies within the upper layer of the earth, from surface mines (Fricke, 2006) . This ore can include metals such as iron, copper, coal and gold. There are several methods of surface mining, including openpit, stripping, dredging and mountaintop removal.

Surface mining Surface mining techniques are used when a vein of coal or other substance lies so close to the surface that it can be mined with bulldozers, power shovels, and trucks instead of using deep shaft mines, explosive devices, or coal gasifiion techniques. Surface mining is especially useful when the rock contains so little of the ore being mined that conventional techniques, such ...
