In the recent years, with the increasing excavation depth and the truth of double-level mining, drifts were strongly deformed and severely damaged in the second mine block in the Jinchuan mine. Some drifts couldn't be used normally even being repaired for many times. The geostatic emergence is very obvious. The crevasses in the surface have been occurred and enlarged quickly.
近年来，金川主力矿山二矿区随着采掘深度的不断加深以及双中段回采，水平矿柱与垂直矿柱已经形成，其地压显现明显，巷道工程变形破坏严重，个别严重地段经多次返修都无法正常使用，地表裂缝出现并加速扩展，采场与充填体时有冒顶发生。
