摘 要:对金龙煤矿开采一1煤进行了突水系数和隔水层安全厚度两方面的评价,得出结论:金龙煤矿开采一1煤具有奥灰突水危险性。对一1煤带压开采可行性进行了分析,提出了采取短壁工作面开采、注浆加固奥陶系岩溶裂隙发育地段、疏降底板高承压含水层水压、建立强有力的排水系统等防治水措施。To realize safe coal mining under safe water pressure of aquifer,according to the evaluation on water bursting coefficient and safe thickness of aquifuge for mining Ⅰ1 coal seam in Jinlong Coal Mine.It was summarized that mining Ⅰ1 coal seam has the hidden danger of ordovician limestone water outburst.Some countermeasures were proposed,such as short wall mining,strengthening the karst fissures development zones by grouting,releasing water pressure of floor aquifer with high pressure,constructing high efficient water drainage system,and so on.The author hold that it is possible to realize the safety mining of Ⅰ1 coal seam.
