Coalbed Methane Potential of the Southern Coal Basin of Belgium

摘要

belgium has a long history of gathering and using gas in association with coal mining operations. In the Southern coal basin (Wallonian coal basin) of Belgium, methane was intensively gathered from gassy seams during coal mining in order to prevent firedamp hazards. In deep coal fields (up to 1450 metre depth in the deepest colliery), gas content of more than 20 m~3 per tonne of coal in place were frequently recorded.
