根据巷道地质条件和原岩应力测量以及煤岩层冲击倾向鉴定结果,运用离散元数值计算分析方法对冲击地压煤巷锚杆支护进行设计,并在生产实践中进行全面矿压观测,找出适应冲击地压条件下的煤巷锚杆支护方式。
According to the geological conditions of the roadway and the original rock stress measurement and the rock burst propensity assessment result, the discrete element numerical calculation method is used to design the bolting support in the coal seam roadway with bursting pressure, and the comprehensive underground pressure observation is carried out in the production practice to find out Coal Roadway Bolt Support Mode Adapted to Rock Burst.
