摘要
米山煤业15112运输巷受断层影响破坏严重,本文采用现场实测、数值模拟的方法对其进行了研究,提出增大支护强度+喷射混凝土的联合支护措施对其进行治理。现场监测结果表明,巷道围岩稳定性在优化方案的支护下得到了显著提高。
The 15112 transport roadway of Mishan Coal Industry was seriously damaged by faults,this paper uses the method of field measurement and numerical simulation to study it,the combined support measures of increasing support strength+shotcreting are put forward.The field monitoring results show that the stability of roadway surrounding rock is significantly improved under the support of the optimization scheme.
