摘要
深部煤层开采由于地质条件复杂,常伴随着大量的地下水涌入,严重影响生产安全.通过分析深部煤层开采中水害的发生机理,总结现有的水害预测技术方法,重点研究了填充开采、设置防水闸门、煤层底板加固注浆等深部煤层开采矿井的防治水技术.综合运用各项防治水技术,可以有效控制和降低深部煤层开采中的水害危险,保证矿井安全高效开采.
Abstract
Due to complex geological conditions,deep coal seam mining is often accompanied by a large amount of groundwater inflow,which seriously affects production safety.By analyzing the occurrence mechanism of water disaster in deep coal seam mining,this paper summarizes the existing water disaster prediction technology methods,and focuses on the water prevention and control technology of deep coal seam mining,such as filling mining,setting waterproof gate,coal seam floor reinforcement grouting,etc.The comprehensive use of various water prevention and control technologies can effectively control and reduce the risk of water disasters in deep coal seam mining,and ensure the safe and efficient mining of the mine.
