摘　　要：四川华蓥山龙滩煤矿属于煤与瓦斯突出矿井,井田内断层构造发育,煤层条件极为复杂,瓦斯灾害相当严重。采掘工作面前期实施区域防突措施时,因地质构造、人员操作及后期抽放管理等因素,采掘工作面易形成地质、抽放、施工误差等类型的盲区。各种抽采盲区均制约着矿井安全生产,威胁职工生命安全。龙滩煤矿提出利用中低压水力压裂补充治理采掘工作面抽放盲区的技术方案,在瓦斯盲区治理方面取得了突破性进展。Longtan coal mine in Huayingshan,Sichuan province is a coal and gas outburst mine.The fault structure in the mine field is developed,the coal seam conditions are very complex,and the gas disaster is very serious.When the regional outburst prevention measures are implemented in the early stage of the mining face,due to the geological structure,personnel operation and later extraction management and other factors,the mining face is easy to form blind areas of geology,extraction,construction errors and other types.All kinds of blind areas restrict the safe production of mine and threaten the life safety of workers.Longtan coal mine puts forward the technical scheme of using medium and low pressure hydraulic fracturing to supplement and control the blind area of extraction face,which has made a breakthrough in gas blind area treatment.
