Analysis on Mechanism and Control Technology of Bottom Drum of Pulley Road under Side Pressure Recovery

针对井工一矿9110工作面回采巷道严重底鼓变形问题,分析研究巷道底鼓的破坏因素和发生机理,提出"起底+顶帮底联合加强支护+超前支护+底板防水"的综合防治措施,使巷道底鼓现象得到有效控制,保障了矿井安全高效生产。

In view of the serious deformation of bottom drum in the 9110 working face of No.1 Mine,this paper analyzes and studies the failure factors and occurrence mechanism of bottom drum of roadway,and puts forward the comprehensive prevention and control measures of "base+top and bottom joint strengthening support+advance support+floor water control",so that the phenomenon of bottom drum of roadway is effectively controlled and the safe and efficient production of the mine is ensured.
