Methane detection in mine ventilation systems

11/04/2018  The most common source of mining accidents, particularly in coals mines, is an explosion of methane gas. Methane is a colourless, odourless gas which is trapped in mines as part of the coal formation process. As coal is formed from compressed plant matter methane is produced as a by-product then, when rocks are excavated, methane is released into the local atmosphere with potential deadly ...

Mine Explosions - an overview ScienceDirect Topics

The gas drainage system method led to collection of the gas at the surface from active underground mines and in the advance of mining, which in turn led to industrial and commercial uses of coalbed gas. The technology used toward drainage and collection of CMM led to development of gas from virgin coal beds with the original coalbed gas wells. Presently, coalbed gas is emitted from coal mines ...

Guidance about explosion hazards - Department of

An explosion is a sudden and rapid increase in volume and release of energy in an extreme manner. This is usually accompanied by the generation of high temperatures and release of gases caused by changes in pressure, temperature and phase. In mining, explosives are the most obvious form of explosion hazard. Blasts and shots are controlled releases of chemical energy. However, the
