摘　　要：针对龙固煤矿复杂的地质条件,通过整理现有物探及钻探资料,对该矿东三采区水文地质概况进行统计分析,确定延伸巷在掘进过程中探水钻孔布置方式及深度,在巷道掘进过程中加强底板富水性探测并制定防治水方案,同时结合相对隔水层分布,并基于底板富水性的分布规律及岩石力学特性的研究基础上,确定巷道底板注浆改造层位及改造厚度。Based on complex geological conditions in Longgu Coal Mine,through the existing geophysical and drilling data,the statistical analysis was carried out about the hydrogeological overview of east third mining area. The layout and depth of extension roadway water exploration drilling was determined in the driving process of extended roadway,during the roadway excavation,the water-abundance detection of floor was strengthened and the program of water prevention and control was made. Combined with the distribution of relative water-resisting layer,in view of rock mechanics and floor water-abundance distribution,the grouting reconstruction position and thickness of roadway floor were determined.
