【摘要】 山西煤田生气物质基础雄厚，总生气量约２５０Ｔｍ￣３．后期改造作用，使煤成气的赋存，高沼矿并及煤与瓦斯突出矿井的分布，都有明显的规律性。理论计算总资源量约０．９Ｔｍ￣３．晋中断陷盆地、河东煤田及临猗预测区，有深层气藏前景；沁水煤田南北两端，河东煤田复式背斜有浅层气藏前景；煤层有丰富的ＣＨ＿４潜在资源。ＣＨ＿４高含量区可采用矿井和地面钻孔抽放。更多还原

【Abstract】 Shanxi coalfields are abundant in the resources of gas generation, the total gas produc-tion is about 250Tm￣3.Through paulopost transformation,the regularity of the occurrence ofcoal gas and the distribution of methane mine, and gas-burst mine are notice obvious. Thefault basins of central Shanxi,Hedong coalfield and Linyi prediction area have foreground ofdeep bed gas;and those of the shallow bed gas are predicted in the south and north ends ofQinshui coalfield and composite anticline of Hedong coalfield.The coal seams are rich in po-tential resources of methane,The methane of high content areas can be exploited and ultitl-ized by ground well or hole outgassing.更多还原
