摘　　要：店坪煤矿9-208工作面地表建有郝放沟骨干坝,为了实现水坝下安全采煤,根据店坪煤矿井上下实际地质采矿条件及相关资料,应用覆岩裂高理论及概率积分法分别对水坝下穿采工作面的可行性进行安全论证,继而应用数值模拟对理论分析结果进行验证,最终综合分析、评价和论证,结果表明,9-208工作面采掘不会对水坝坝体造成破坏影响,采取的技术措施为骨干坝下安全采煤提供了可靠的技术支撑。Haofanggou backbone dam is built on the surface of working face 9-208 of Dianping Coal Mine.In order to realize safe mining under the dam,according to the actual geological mining conditions and relevant data above and below the mine of Dianping Coal mine,the overburden fracture height theory and probability integral method are applied to conduct safety demonstration on the feasibility of mining working face under the dam,and then the theoretical analysis results are verified by numerical simulation.The final comprehensive analysis,evaluation and demonstration show that the mining of 9-208 working face will not cause damage to the dam body,and the technical measures adopted provide reliable technical support for safe coal mining under the backbone dam.
