摘要: 针对枣泉煤矿12205工作面运输巷围岩地质条件变化复杂,原有支护不能有效控制围岩变形,采用数值模拟和现场监测的方法,对该巷道支护方式进行优化研究,提出了优化后的支护方式为锚网索+注浆+钢梁、钢棚等多介质耦合支护。结果表明,支护方式优化后巷道顶底板移近量为10~80 mm,变形速度较小,围岩变形趋于稳定;巷道围岩高应力区扩大了约1 m,围岩松动圈范围缩小至1.2~2.0 m。结果证实优化后的支护方式能充分发挥围岩与支护体的整体力学效应,变载荷为承载体,增加了围岩自身的承载能力,对巷道围岩的稳定性起到了较好的支护效果。Abstract: According to the variation and complicated surrounding rock conditions of the transportation gateway in No. 12205 coal mining face of Zaoquan Mine, th e previous support could not effectively control the deformation of the surrounding rock. An optimized study was conducted on the support method of the gateway. The 0 ptimized support method was a multi medium coupling support with bolt 1 steel mesh 1 anchor + grouting + steel beam, steel square support and others. The computer n umerical simulation and the site monitoring and measuring method were applied to the support effect analysis on the support method after the optimization. The results showed that after the optimization of the support method, the convergence between the roof and floor of the gateway was 10 ~ 80 mm, the deformation speed was slow and the deformation of the surrounding rock was in stable. The high stress scope of the gateway surrounding rock was expanded about 1 m and the loose scope of the surrounding rock was reduced to 1. 2~ 2.0 m. The support method optimized could fully play the integrated mechanics effect between the surrounding rock and suppor t mass, the load could be changed as a loading mass and thus the loading capacity of the surrounding rock was enhanced, which would provide good support effect to t he stability of the gateway surrounding rock.
