The Status Quo and Plans on CBM Exploitation & Utilization inShanxi Coking-Coal Mining Areas;

Based on the gas testing of geological prospecting hole and exhaust testing informations of well in Jiaozuo mining area,review and evaluation on coalbed gas resources and features of reservoir of Shanxi formation in Jiaozuo coalfield,and probed into the favourable exploitation section and exploitation method of coalbed gas in the area.

In order to study the difference and its controlling mechanism of gas adsorption on coals with different body structures,such parameters as the macroscopic petrographic constituents,the adsorption capacity and pore structure of undeformed and mylonitic coal samples of Jiaozuo coalfield,were measured.
