COAL - Earth Sci

2017-9-18  Conventional mining is the oldest method and accounts for only about 12% of underground coal output. In conventional mining, the coal seam is cut, drilled, blasted and then loaded into cars. Continuous mining is the most prevalent form of underground mining, accounting for 56% of total underground production. In continuous mining, a machine ...

In room and pillar mining, pillar extraction can be so designed that mined out area is submerged in water.This provides excellent inertization but is possible only in highly inclined coal seams. Most commonly, self-inertization is provided by the methane gas released from coal seams in the gas emission space.
