挖金湾煤业矿井下巷道水害防治方案的应用

Application of Water Hazard Prevention Scheme for Underground Roadway in Jinwan Coal Mine

为了解决挖金湾煤业5137 底抽巷在综采作业过程中出现涌水,严重影响煤矿井下综采作业安全的情况,结合井下实际地质条件,提出了建立防水闸墙、突水点封堵注浆等防治水害的技术方案。根据在挖金湾煤业5137 底抽巷的实际应用表明该综合水害防治方案具有显著的效果。

In order to solve the problem of water gushing in the fully mechanized mining operation of the 5137 bottom drainage roadway in Wajinwan Coal Industry,which seriously affects the safety of fully mechanized coal mining operation,combined with the actual geological conditions in the coal mine,this paper puts forward a technical scheme to prevent and cure water damage,such as waterproof sluice wall and sealing grouting at water inrush point.According to the practical application of the 5137 bottom drainage roadway in Wajinwan Coal Industry,the comprehensive water hazard control scheme has remarkable effect.
