Comprehensive Analysis of Safe Mining Underneath the Xitian River at Lingxin Coal Mine of China

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.
