1.
1 mine ,the moving displacement of side-to-side and roof-to-floor in roadway is too big due to the roadway pressure and the weak coal rock, and because the traditional U bracing trellis is not effective ,thus ,the control measure of the enhancement of the bolt for the weak coal rock has been adopted to achieve good effect.
潘一矿东翼-530m--800m暗主斜井,在过C13-1煤层时,由于巷压较大、煤岩松软等原因,造成巷道围岩移近量过大,传统的U型棚支护已不能发挥作用,通过采取锚杆补强的控制措施,取得了良好效果。
