摘　　要：为解决急倾斜煤层采掘过程中的水害威胁,通过分析矿井与地表的水力联系、与老窑关系的调查,对矿井水害威胁程度及水害事故进行分析,采取地面小窑开采塌陷坑治理、施工排水沟、帷幕注浆等手段,减少地面水入井;井下采取细化水文资料管理、优化采掘布局、强化探放水工程的措施,消除矿井水害威胁,保障矿井生产安全。In order to solve the water hazard threat in the mining process of steeply inclined coal seam,through analyzing the hydraulic relation between mine and surface,investigating the relation with old kiln,analyzing the degree of mine water hazard threat and the water hazard accident in history,we should reduce the surface water entering well by means of pit treatment,drainage ditch construction and curtain grouting.In order to eliminate the threat of mine water disaster and ensure the safety of mine production,the measures of refining hydrological data management,optimizing mining layout and strengthening water exploration and drainage engineering are adopted.
