摘要
通过对岳城煤矿13093巷围岩特性进行数值模拟和现场分析,确定合理的顶板支护补强方案。经过现场实践可看出,采用密集型锚索补强的支护方式,可以改善该区域围岩应力的特性,有效实现控顶控帮。
Based on numerical simulation and field analysis of surrounding rock characteristics in 13093 Lane, Yuecheng Colliery, a reasonable roof cable supplement support scheme has been determined, which can improve the characteristics of surrounding rock stress in this area and effectively realize roof and rib spalling control.
