Abstract: 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.
