摘　　要：山西晋城兴唐煤业有限公司车寨煤矿为高瓦斯矿井,综合分析了该矿3号煤层瓦斯赋存状况,认为提前对该煤层进行瓦斯抽采是非常必要的。经过技术、安全和经济可行性论证后,采取了地面钻井压裂预抽煤层瓦斯技术。预抽煤层瓦斯效果表明,地面钻井压裂预抽煤层瓦斯技术可行、安全可靠、经济合理,能够对煤层瓦斯进行有效预抽,为矿井安全生产奠定了基础。Chezhai coal mine of Shanxi Jincheng Xingtang Coal Industry Co.,Ltd.is a high gas mine.Based on the comprehensive analysis of the gas occurrence of No.3 coal seam,it is considered that it is very necessary to carry out gas drainage in advance.After the technical,safety and economic feasibility demonstration,the surface drilling fracturing pre drainage coal seam gas technology is adopted.The effect of pre pumping coal seam gas shows that the surface drilling fracturing pre pumping coal seam gas technology is feasible,safe,reliable,economical and reasonable,and can effectively pre pump coal seam gas,which lays a foundation for mine safety production.
