深部巷道破坏机理研究

Study on Failure Mechanism of Deep Roadway

利用FLAC-3D模拟软件对深部巷道的受力情况进行分析和研究,对比了原支护系统下的巷道应力分布情况和采用钻孔卸压后的巷道应力分布情况,为矿山解决深部巷道变形大、来压强的问题提供了一定的解决方案,提升了巷道的稳定性和安全性。

In order to solve the problems of strong ro ck burst and large deformation of deep roadway in coal seam mining in China,this paper uses FLAC-3 D simulation software to analyze and study the stress of deep roadway.The stress distribution of the roadway under the original support system and the stress distribution of the roadway after the pressure relief by drilling holes are compared.It provides a certain solution for solving the problem of large deformation and pressure of deep roadway,and improves the stability and safety of roadway.
