摘　　要：通过钻孔采样选取岩芯进行实验测试,结合煤层构造、地层特征等诸多条件,对区域煤质特征、孔隙结构、含气性、渗透性特征进行研究。结果表明:研究区域煤层多呈黑色,金刚光泽;煤层中有机组含镜质组和惰质组;煤的内生裂隙较发育,煤层平均储层压力偏低;沁水南部寺河矿区,含煤地层的煤层气资源丰富。研究结果对今后煤层气产能的提高,跨区域技术移植及煤矿瓦斯的治理都具有一定的实际意义和理论价值。The core test was carried out by drilling and sampling,and combined with coal seam structure and stratum characteristics,this paper studied the characteristics of coal quality,pore structure,gas content and permeability. The research indicates that the majority of coal seam is black and appears adamantine luster,the organic components in coal bed include vitrinite,semivitrinite and inertinite,the inner fractures of coal are relatively developed,the average reservoir pressure of coal is low,the coal bed methane resources are abundant in the Sihe mining area in the south of Qinshui. Through research and analysis of reservoir characteristics in this area,it is conducive to the improvement of coalbed methane production capacity in the future. As the meanwhile,it has practical significance and theory value in terms of cross-regional technology migration and control of coal mine gas.
