COAL SEAM METHANE
Methane gas is held captive in virgin coal and is released during
the mining process. Depending on the quantity of gas present removal
of the methane rich gas or “gas drainage” is required
prior to, during and after the extraction of coal. The methane content
in the underground ventilation system must be maintained under strict
control to ensure the safety of personnel working underground.
Until recently such methane rich gas was regarded as a waste product
and vented to atmosphere. Beginning in the 1970s and 1980s in Europe
projects were initiated to utilize the gas for power generation
By the 1990s gas utilization technology for power generation was
mature with operating plants of several megawatts in Europe, USA,
China and Australia.
In the new millennium, as concerns grew over environmental matters
in general and global warming in particular, further attention was
focused on utilizing the methane rich waste mine gas to offset coal
fired generation and reduce greenhouse gas emissions.
As environmental restrictions become more stringent, waste mines
gas utilization via generation offers a unique opportunity to industry
to reduce energy costs while providing an environmental benefit.
Maintain Power has built an enviable reputation in the field of
waste mine gas and coal seam methane utilization.
Beginning with our involvement in coal seam methane utilization
in the 1990s in the United Kingdom our keynote projects in this
- Tower Colliery UK
- Tahmoor Colliery, New South Wales Australia
- Moranbah CSM plant , Queensland Australia
- Shanxi Asian American Project, China
- Teralba Colliery, New South Wales Australia
- Oaky Creek Colliery, Queensland Australia
- BHP Billiton WestVAMP Project, New South Wales, Australia
Maintain Power’s involvement in these projects has ranged
from feasibility studies and tender preparation through to construction
and commissioning services and on going operational support.
We are justifiably proud of our role in the two most recent waste
mine gas projects to become operational in Australia.
