摘要
通过系统分析梁北煤矿矿井水文地质条件,利用聚类分析、数值模拟、物探等方法,研究了矿井突水条件和突水机制,并结合矿井前期防治水实践,提出了疏水降压与寒灰顶部注浆改造煤层底板相结合的综合防治水技术。应用该技术,矿井已安全生产煤炭210万t,取得了较好的经济效益。
Based on the systematical analysis of hydrogeology conditions,study was made on the water-inrush conditions and mechanics by using the methods of cluster analysis,numerical simulation and geophysical prospecting.Compared to the former experience of water-inrush control,the comprehensive technology of groundwater drainage and grouting into the roof of Cambrian limestone aquifer for reconstructing the floor was proposed.By applying this technology,2.1 million ton of coal was safely extracted from the mine,and better economic benefits were obtained.
