摘要
凤凰山煤矿15~#煤三盘区XV3307综采工作面两顺槽顶板和两帮均采用锚梁支护,顶板采用锚索补强支护。从矿压监测数据来看,巷道未发生较大的变形,说明支护设计合理,保持了巷道围岩的整体稳定,充分发挥了锚杆、锚索支护的主动性,起到了主动支护的效果。
The top plate and two sections of XV3307 fully mechanized working face in Fenghuangshan coal mine are supported by the anchor beam. Analysis of mine pressure monitoring data shows that the roadway has not gone through large deformation, and that the supporting design is reasonable, which has maintained the overall stability of the surrounding rock of roadway, and has given full play to the initiative of the anchor rod, anchor cable.
