Type Analysis on Coal Mine's Water Hazards in Fenxi Mining District of Shanxi Coking Coal Group and Prevention Measures

根据汾西矿区各矿井普遍受老窑、小煤矿采空区积水、地表水、冲积层水、含水层水威胁的现状,通过近年来发生的典型水害案例阐述了矿区各种水害发生的特点、对煤矿安全生产影响及危害程度,结合矿区防治水害工作开展现状,分析了各种水害发生的原因和防治水害工作中存在的主要问题,针对各种水害提出了具体的防治措施和对策,指出只有针对不同的水害类型,坚持防重于治,完善探查手段,建立健全防治水害机构和制度,加强技术管理和重视工程投入,才能防止重大水害事故的发生。

According to the present situation of each mine in Fenxi Mining District of being threatened by accumulated water,surface water,alluvial water and aquifer water in old mines and mined-out areas of small mines,and based on typical mine flood cases happening in resent years,this paper expounds the characteristics of various water hazards happening in mining districts and their influences on coal mine＇s safety in production,and connecting with the current status of water hazard prevention,analyzes the reasons of various water hazards and and main problems existing in water hazard prevention,puts forward some concrete measures for preventing various water hazards,and points out that in order to prevent heavy water hazard,it is necessary to make clear the types of water hazards,persist in the principle of that the prevention is the first,improve the detection means,establish and perfect the organization and system for the prevention and control of water hazards,and strengthen the technological management and value the engineering investment.
