摘要
通过对21181综放工作面的突水特征与突水水质检测资料的分析,以及开采导水裂隙带高度的计算,得出了工作面突水原因——采煤后形成的导水裂隙带已波及到了上覆侏罗系上统巨厚砾岩含水层,通过运用合理的防治方案,为今后综放工作面预防水害打下了基础。
Through analyses of water bursting characteristics and water quality testing data, as well as mining activated water conducted fracture zone height estimation worked out the reason of working face water bursting - the water conducted fracture zone formed after mining activities is already reached to the overlying Upper Jurassic very thick conglomerate aquifer. Put forward reasonable controlling schemes, thus has laid a foundation to water disaster controlling of fully mechanized sublevel caving faces henceforth.
