Thanks to our vast experience of working on landfill gas utilisation projects around the world, we are also able to offer a one-stop-shop solution for mines gas applications.
Rather than being considered a harmful emission or hazard, methane gas is now viewed by the mining sector as a valuable resource. De-regulation of energy markets and changes to the oil and gas exploration licensing regime have opened up the potential to utilise mines gas to fuel small-scale 'embedded' generators.
We work with companies involved in both coal mine methane and coal bed methane.
Coal mine methane (CMM):
CMM is a methane rich gas present in active and abandoned mine sites. This gas is either extracted from the air and coal in the active coal mine, or from the gas filled void of the abandoned coal mine, helping improve safety and preventing uncontrolled release of methane to atmosphere.
Coal-bed methane (CBM), coal-bed gas, coal-seam gas (CSG), or coal-mine methane (CMM) is a form of natural gas extracted from coal beds. In recent decades it has become an important source of energy in United States, Canada, Australia, and other countries.
The difference between the two is explained in the diagram below.
Mines gas benefits:
Under the Global Greenhouse Gas (GGHG) Emissions monitoring scheme, all coal producing countries have an inventory or the emissions produced by its actions. The mining sector contributes significantly if it does not control directly, at the source of its operation, the pure methane being released to the atmosphere.
Typical GHG are:
