以偃龙煤田西部岩溶水系统为实例，分析了单斜岩溶水系统特征及其对煤矿开采的影响，阐明了单斜岩溶水系统中，补给区的水文地质条件相对简单，岩溶水对煤矿开采的影响较小。而在系统的排泄区，岩溶较为发育，水文地质条件较为复杂，因此岩溶水对煤矿开采的威胁较大。
Taking the karst water system in the west of Longlong Coalfield as an example, the characteristics of monocline karst water system and its influence on coal mining are analyzed. It is clarified that the hydrogeological conditions of the recharge zone are relatively simple in the monocline karst water system, Less affected. However, in the drainage area of the system, the karst is more developed and the hydrogeological conditions are more complicated. Therefore, the karst water poses a great threat to the coal mining.
