Environmental Protection in Surface Mining of Coal

The current expansion is due mainly to the greater pro- duction per man day, lower production costs; these result from new technology, which has produced equipment that has made strip mining highly productive and efficient. In 19UO, 9.h% of the total coal production was from surface mining, the 1972 figures show an increase to k9% (Table 5).

Environmental impact of the coal industry

Water managementEdit. When coal surfaces are exposed, pyrite comes in contact with water and air and forms sulfuric acid. As water drains from the mine, the acid moves into the waterways; as long as rain falls on the mine tailings the sulfuric-acid production continues, whether the mine is still operating or not.

An Introduction To Surface Mining

Mining is merely defined as digging in the ground to find something of use. The process has been a part of life since antiquity, and is still the backbone of the world's commerce and production. Mining could be classified in two forms: mining at the earth's surface (surface mining) and mining underground (subsurface mining).

How coal is produced?

Coal can be extracted from the earth either by surface mining or underground mining. Once coal has been extracted, it can be used directly (for heating and industrial processes) or to fuel power plants for electricity. If coal is less than 61 meters (200 feet) underground, it can be extracted through surface mining.

Subbituminous: Subbituminous coal is black in color and dull (not shiny), and has a higher heating value than lignite. Lignite: Lignite coal, aka brown coal, is the lowest grade coal with the least concentration of carbon. Also, there is peat. Peat is not actually coal, but rather the precursor to coal.
