摘要
通过软弱夹层诱发锚杆支护巷道冒顶的实例,进行了软弱夹层位置对巷道自稳影响的计算机数值模拟分析。提出了一种顶板岩层结构探测方式,介绍了该探测方式在焦作古汉山煤矿应用的情况。
Through the case that soft and weak band induces roof-fall of roadway with bolting, the computer value simulation analysis for the influence of the location of weak band on the stability of roadway itself. A detection method of roof strata structure is put forward and the application of the method in Guhanshan coal mine in Jiaozuo is introduced.
