MINING METHODS |authorSTREAM
Open pit coal mining has been popular in Europe, but is used on a more limited basis in the United States for lignite extraction in the northern Great Plains and for Wyoming subbituminous coal. The method is a type of area stripping which allows almost complete removal of coal from very thick seams, using a mining approach reminiscent of rock quarrying.

Surface Mining. Surface mining methods include area, contour, highwall and mountaintop removal. Area mines are surface mines that remove shallow coal over a broad area where the land is fairly flat. After the coal has been removed, the overburden is placed back into the pit. Contour mines are surface mines that mine coal in steep,...
HOW IS COAL MINED AND PRODUCED? 360 290
Coal is mined by two methods: surface or 'opencast' mining, and underground mining. The choice of mining method largely depends on the geology of the coal deposit. Underground mining currently accounts for a bigger share of world coal production than opencast; although in several important coalproducing countries, surface mining is more common.
Coal mining — Wikipedia Republished // WIKI 2
Most coal seams are too deep underground for opencast mining and require underground mining, a method that currently accounts for about 60 percent of world coal production. In deep mining, the room and pillar or bord and pillar method progresses along the seam, while pillars and timber are left standing to support the mine roof.

Mar 21, 2014· Coal is one of the mostwater intensive methods of generating electricity. A typical coal plant withdraws enough water to fill an Olympicsized swimming pool every three and a half minutes. The International Energy Agency says that global water consumption for power generation and fuel production is expected to more than double from 66 billion cubic meters (bcm) in 2010, to 135 bcm by .

mining process when the coal seam is fractured. Methane released in this fashion will escape into the mine works, and will eventually escape into the atmosphere. The amount of CH4 released during coal mining depends on a number of factors, the most important of which are coal rank, coal seam depth, and method of mining.

"Coal mine methane (CMM) and abandoned mine methane (AMM), are byproducts of underground coal mining. The quantity and the emission rate of CMM and AMM may vary depending on the type of mine, gas content of the mined coal seam, and gas sourced from strata and coal beds in overlying and underlying formations affected by mining.
