摘　　要：矿井水害一直是制约煤矿生产的重大灾害之一,随着煤矿开采深度增加,矿井突水危险性也大大增强。通过分析研究得出茅口灰岩赋存状况及岩溶发育规律;以黔北某矿为例,运用"下三带"理论预测分析开采龙潭煤组底层煤的突水危险性;并提出具有针对性的防治措施,为预防底板茅口灰岩岩溶水灾害提供科学依据。Mine water accident has been one of the major disasters that influencing coal mine production.Along with coal mining depth increased,the risk of mine water bursting greatly enhanced.Through the analysis of occurrence condition of spear mouth limestone and karst development law;take Qianbei Coal Mine as an example,using Three Underlying Belts theory forecast and analyze water burst of ground floor coal of Longtan coal mine;and put forward some corresponding prevention and control measures,thus providing scientific basis for preventing water disasters of baseboard of spear mouth karst limestone.
