深部煤层开采矿井水害成因与防治技术

Mine water hazard genesis and its prevention and control technology for deep coal seam mining mines

为促进深部煤层开采的安全和可持续发展,对深部煤层开采矿井水防治的关键技术和措施进行探讨。在分析水害成因和矿井水质量控制重要性的基础上,对井下直流电检测法、瞬变电磁检测法和音频电穿透视检测法等矿井水害检测技术的优缺点和适用范围进行论述,并对填充开采、防水闸门、煤层底板加固注浆和奥灰疏水降压等矿井水害防治技术进行介绍。最后,强调了水质监测与分析、水处理技术、水质调控与调节等防治水质量控制措施的重要性。

In order to promote the safety mining and sustainable development of deep coal seam mining,we explore the key technology for water prevention and control during deep coal seam mining.Firstly,the genesis of water hazard and the importance of quality control of mine water were introduced.Secondly,the advantage and disadvantages of detection technologies of mine water hazard and their applicable ranges were discussed,including underground direct current detection method,transient electromagnetic detection method,and audio electric penetration perspective detection method.Then,water prevention and control technologies were introduced,such as filling mining,waterproof gates,coal seam floor reinforcement grouting,and Ordovician limestone drainage and pressure reduction.Finally,emphasis was placed on water quality control measures,including water quality monitoring and analysis,water treatment technology,and water quality regulation.
