摘要
由于富水层顶板工作面回采巷道向斜轴附近水平较低,极易使向斜轴附近回采巷道排水不力形成肓巷。文中通过对回采巷道向斜轴附近充水因素的分析,给出了工作面的正常与最大涌水量计算公式,提出了三种防治回采巷道向斜轴附近水患的措施,较好地控制了由于工作面涌水造成回采巷道向斜轴附近水患问题。为同类条件下回采巷道的水患防治提供了一定的借鉴作用。
Due to low level of roadway near inclined shaft in rich water roof face, don＇t drain away water in time to be easy formed blind-roadway. This paper through the analysis of the factors of water filling and obtained the water inflow calculation formulas of normal working and maximum yield, putting forward three kinds of prevention floods near inclined shaft in roadway, it better control problem of floods near inclined shaft in roadway due to face water inflow. It provided certain reference for preventing floods in similar roadway.
