针对崔木煤矿21301工作面压架突水,研究了冒落带与上部延安组顶板和直罗组砂岩含水层富水区沟通,导水裂隙带与上部白垩系洛河组含水层导通,对下部含水层形成补给。分析了突水灾害发生的原因,通过采取严格控制采高、实施间隔放煤、加强超前支护等措施,来避免压架突水事故。相关经验措施可以为崔木煤矿类似受压架突水威胁工作面的顺利回采提供参考和借鉴。
In view of the pressure bursting in 21301 working face of Cui Mu Coal Mine, the communication between the caving zone and the roof of Yan’an Formation and the water-rich reservoir of Zhiluo Formation sandstone was studied. The water-bearing fractured zone and the Upper Cretaceous Luohe Formation aquifer lead, Replenishment of the lower aquifer. The causes of water inrush disaster are analyzed. The measures such as strict control of mining height, interval coal release and advanced support are adopted to avoid the inrush of water ram. The relevant experience and measures can provide reference and reference for the smooth mining of Cui Mu coal mine similar to the water-inrush face of water pressure.
