为了研究彬长矿区煤岩孔隙特征,采集彬长矿区大佛寺煤矿4#、4#煤层和胡家河煤矿4#煤层样品,通过肉眼挑选出宏观煤岩组分中的镜煤和暗煤,分别进行低温液氮吸附、扫描电镜实验。结果表明,大佛寺井田4#、4#煤层更有利于煤层气资源勘探开发;相对于镜煤而言,暗煤更有利于煤层气资源勘探开发。
In order to study the pore characteristics of coal and rock in Binchang mining area, 4 # and 4 # coal seam of Dafosi Mine in Binchang Mining Area and 4 # coal seam in Hujiahe Mine were collected, and the microscopic coal and dark coal in macroscopic coal and rock components were picked out by naked eyes, Low Temperature Liquid Nitrogen Adsorption, Scanning Electron Microscopy Experiment. The results show that the 4 # and 4 # coal seams in Dafosi Mine Field are more favorable for the exploration and development of coalbed methane resources. Compared with the mirror coal, the dark coal is more conducive to the exploration and development of coalbed methane resources.
