DEVELOPING ECOLOGICAL RESTORATION MODEL IN

2015-12-10  Coal is a most important and abundant fossil fuel having a proven reserve of 860 billion tons, out of which 55% of it is being utilized in meeting country’s energy demand. The power sector followed by iron, steel and cement segments are the largest consumer of coal in India. Thus, it becomes inevitable for continuous mining of coal.

Subsurface coal-mine fires: Laboratory simulation,

2007-1-1  Subsurface coal-mine fires occur in many mining regions, especially where coal has been previously excavated by “room-and-pillar” mining methods. The surface above these fires heats up to produce a thermal anomaly. The shape of the temperature profile over the fire zone holds clues to the depth of the underground fire.
