煤矿井下综合防治水技术的应用研究

Research on Application of Comprehensive Water Control Technology in Coal Mines

针对煤矿井下复杂地质条件下顶板水防治和巷道支护困难的现状,提出了一种新的煤矿井下综合防治水技术。在对复杂地质条件下井下防水所面临的困难进行充分分析的基础上,采用定向钻进勘探、富水区域疏水、顶板脆弱区域综合支护的方式,实现了对井下复杂地质条件下的综合防水。实际应用表明,新的综合防治水方案能够有效防止巷道掘进过程中发生突水事故,极大地提升了巷道掘进的安全性和可靠性。

In view of the difficult situation of roof water prevention and roadway support under complex geological conditions in coal mines,a new comprehensive water control technology in coal mines was proposed.Based on the full analysis of the difficulties faced by underground waterproof under complex geological conditions,the comprehensive waterproof under complex geological conditions was realized by means of directional drilling exploration,drainage in water rich area and comprehensive support in vulnerable area of roof.The practical application shows that the new comprehensive water control scheme can effectively prevent water inrush accidents in the process of roadway excavation,and greatly improve the safety and reliability of roadway excavation.
