掘进工作面顶部采空积水的物探分析

Study on Detection of Goaf Seeper in Upper Part of Heading Face

根据防治水"有掘必探、先探后掘"的要求,针对正升煤业公司掘进东翼回风大巷顶板淋水,计算顶板导水裂隙带高度、物探积水位置及积水量,为安全巷道掘进提供预测预报。

According to the requirement of preventing and controlling water--"exploration must be carried out before excavation",aiming at the water pouring from the roof of the east wing ventilation roadway in Zhengsheng Coal Industry Co.,the height of the roof water flowing fracture zone,the location and amount of water accumulated in geophysical prospecting are calculated to provide prediction and forecast for the safety driving.
