摘要
为了解决巷道在原有支护方案下围岩变形大的问题,利用数值模拟软件对不同锚杆锚固方式、不同顶板角下的围岩应力场进行分析,结合实际地质条件对巷道支护进行了设计,为矿井安全生产提供参考。
In order to solve the problem of large deformation of surrounding rock under the original support scheme,this paper analyzed the stress field of surrounding rock under different bolt anchoring mode and different roof angles by using numerical simulation software,and designed the roadway support according to the actual geological conditions,which can provide reference for mine safety production.
