摘要
为优化12_下202工作面运输巷支护参数,建立6种不同的支护参数模型,选用不同尺寸的锚杆,并运用FLAC3D数值模拟软件进一步优化分析对比,最终确定了最优支护方式及参数,采用高强预应力锚杆、锚索,巷道支护效果明显,节约了支护成本。
In order to optimize support parameters of transportation roadway in 12_下202 working face, six different support parameter models were established. After using different sizes of anchor bolts and FLAC3D numerical simulation software to make further analysis, optimum support mode and parameters were determined finally. At the same time, high strength prestressed anchor bolt and cable were applied. As a result, the effect of roadway support was obvious and support cost was saved.
