摘要
为解决曙光煤矿1226瓦斯治理巷变形破坏严重的问题,采用FLAC3D软件模拟了1226瓦斯治理巷的掘进和工作面的回采,确定支护方案为“高强锚杆+金属网+高强锚索+钢带”耦合支护体系。矿压及锚杆受力监测表明,支护承载体性能得到了较好的发挥,巷道断面收敛量控制在合理的范围内,设计的支护技术有效提高了巷道围岩的稳定性。
In order to solve the problem of serious deformation and damage of 1226 gas control roadway in Shuguang Coal Mine,the excavation and mining of 1226 gas control roadway are simulated by FLAC3D software,and the support scheme is determined as the coupling support system of"high-strength bolt+metal mesh+high-strength anchor cable+steel strip".The monitoring of mine pressure and bolt stress shows that the performance of support bearing body is well developed,and the convergence of roadway section is controlled in a reasonable range,the designed support technology effectively improves the stability of surrounding rock.
