| 摘 要： | 为研究煤层开采对其覆岩含水层的影响情况,通过RFPA2D数值模拟软件,分析了神东矿区补连塔煤矿31401综采工作面采动过程中覆岩的运动规律和导水裂隙的发育情况。结果认为补连塔煤矿31401综采工作面开采过程中,其第三含水层与其上下的砂质泥岩和粉砂岩形成了复合隔水关键层,能够有效保护上面的第一、二含水层,防止地下水资源的流失。

| Abstract: | The movement law of overburden strata and the growth of water flowing fractures in overburden strata during mining advanced process for 31401 fully mechanized working-face of Bulianta coal mine were simulated using rock failure process analysis software(RFPA2D).The result showed that in the advance process of the working-face,the third water stratum together with it's upside mudstone and bottom sandstone strata,can compose the water resisting compound key stratum,which is capable of preserving the first and... |
