摘　　要：区域构造、可溶性岩层和地下水动力条件是岩溶陷落柱形成的3个必备条件。选取刘桥二矿作为研究区,从现有数据中分类提取出区域构造、可溶性岩层和煤层顶底板强富水异常区3个因素,根据底板等高线生成煤层底板坡度图及研究区邻近区域内已探明陷落柱的特征,结合这3个因素,运用GIS叠置分析圈定出4个可能的陷落柱发育区,再经与实际生产情况资料对比,得出巷道揭露的Ⅱ617风巷陷落柱位于第Ⅱ区内。The formation of karstic collapse columns entails three essential prerequisites：tectonics and regional structure,soluble rock,and groundwater hydrodynamics.Firstly the No.2 of Liuqiao coal mine is targeted and the factors are extracted such as soluble rock,tectonics and regional structure,and limestone strong water-rich areas from the available data.Then by using the GIS overlay analysis technology,four areas zone Ⅰ,zone Ⅱ,zone Ⅲ and zone Ⅳ are delineated,which may develop karstic collapse columns according to the slope analysis result of seam floor map and the characteristics of the No.2 of Liuqiao coal mine related areas.Finally,the conclusion is that karstic collapse column in the Ⅱ617 airway is located in zone Ⅱ by comparison with the actual data.
