Theoretical research and practice on coal mine methane eztraction and ground development design

摘要：

This paper, starting with the existence of general introduction of associated coal bed methane (CBM) with coal, expatiates in five parts on the transferrules CBM changing with time in three-dimensional rock space of the coal mine under the effect of mining activity and ventilation; On the basis above, the principle having been validated in practice is also pointed out for us to follow in methane extraction from coal mines. Finally, it draw conclusion that mining areas with high gas concentration(including coal and gas outburst), low permeability, and composite coal seams can realize the coal mine methane (CMM) extraction and ground development in a high efficient way as long as we follow the miming activities and the gas migration rules under the effect of negative pressure ventilation.
