摘要
从西峪煤矿寨沟井田二水平2619、2617工作面采空区上方地表泉水断流10年后又复出的现象出发,对泉水断流、复出并逐渐增大的机理进行了比较全面而深入的研究。得出泉水的复出是由于石岔沟内粉煤灰浆水沿着原来泉水的出口处溢到地表所致。故而进一步推出西煤矿采空区上方地表裂缝不必要充填的结论,也为热电厂处理粉煤灰以及其它煤矿在今后治理、美化矿山环境中指出几条有借鉴意义的方法和途经。
Based on recovery of surface spri ng water after stop flow for 10 years above goaf of 2619,2617 working faces on second l evel of Zhaigou mine field of Xiyu coal mine ,research completely and deeply on the mech anism of spring water recovery,and held tha t recovery of spring water caused by ash mor tar water of fine coal in Shichagou overflo w to the surface along original exit of spri ng water. So further consider that surface fracture above goaf of Xiyu coal mine unnec essarily to fill,and indicated some method s to process ash of fine coal in heat and pow er plant and to harness environment in coal mines.
