摘要
针对新汶矿区千米深井巷道特征,考虑锚杆支护系统本身允许的变形量,将其作为确定顶板离层界限值的重要依据,对评价锚杆支护效果和巷道安全程度具有重要意义。
Aiming at the characteristics of 1000m deep roadways in Xinwen Mining Area, this paper took allowable deformation value of bolt supporting system as important basis of confirming limit value of roof separation, which was important for evaluating supporting effect of bolt and safety degree of roadway.
