| 摘 要： | 因采动白垩系红层压覆下的煤层，从而破坏了白垩系底砾岩岩溶裂隙水的动态平衡，导致白山坪矿白采动前的矿井南翼水量50m^3／h，突增至3700m。／h（1996～1997年），造成矿井6次穿水，2次淹井严重后果。1997年采用帷幕注浆治理，并经近10年运行及多次洪水考验，目前矿井南翼矿井涌水量稳定在150m^3／h之内，一般120m^3／h。帷幕注浆治理矿井水害获得巨大成功。

| Abstract: | Mining the coal bed under the Cretaceous strata destroyed water dynamical equilibrium of the system in the Cretaceous basal conglomerate karst, which caused increase in the leak of the water volume in south the mine pit wing from 50 m^3/ h to 3700 m^3/h suddenly （in 1996-1997 years）. The results were that the mine pit were six times to pumped water out and flooded two times. In 1997 using the curtain note thick liquid government beginning at 1997 and for near ten years after that the leak of the water controlled with 150 m^3/h with general 120 m^3/h, showing the control method is effective. |
