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 quality CMM can be divided into 3 classes, as shown in the tabel below.
| High-Quality Gas
> 50 % CH4 |
Medium-Quality Gas
25% < CH4 < 50% |
Low-Quality Gas
< 4% CH4 |
|---|---|---|
| • Natural gas pipelines
