CMM Utilisation Opportunities

The major part of methane in coal mines is gas deliberating from the broken coal in the surroundings of the longwall and from dug part of the mine. Depending on the location and period of its disposal to the atmosphere, CMM can be divided into 3 classes, as shown in the tabel below.

High-Quality Gas > 50 % CH4	SpalteMedium-Quality Gas 25% < CH4 < 50%	SpalteLow-Quality Gas < 4% CH4
