摘要
为了研究灵新煤矿河下开采引起的覆岩破坏规律和地表移动规律,采用工程地质调查、彩色钻孔孔电视、钻孔冲洗液漏失量法、物理与数值模拟、地应力测量及地表监测等多种研究手段,获得了矿区地应力分布规律、工作面开采的垮落带和导水裂缝带的高度、岩层移动规律及矿压显现规律,实现了L3414综采工作面安全开采和环境保护的双重目标.
In order to study the damage of overburden rock and the surface subsidence caused by water-control mining at Lingxin Coal Mine, the in-situ stress distribution law, the damage height and crack height, the overburden rock displacement law and the ground pressure law were abtained by means of engineering geological investigation, color bore-bole TV inspecting, leakage monitoring in drilling fluid, simulation experiment, numerical computing, in-situ stress measurement and subsidence measurement. The result shows that safe mining at L3414 working face underneath the Xitian River and environmental protection can be implemented ultimately.
