摘要
论文针对某矿大断面(5.5m×3.5m)回采巷道具体地质特征,提出了锚梁网索联合支护的方案,并采用有限差分数值计算程序FLAC2D5.0对巷道支护效果进行了较深入地分析。结果表明,巷道采用联合支护技术是合理的,所选用的主要技术参数是安全的,其支护形式及主要技术参数可为类似条件下的矿井借鉴。
According to the certain geological features of the mining gateway with a large cross section of 5.5m×3.5m in a coal mine, the paper provided the combined support plan with the boh, beam, steel mesh and anchor, With the finite difference commercial calculation program FLAC^2D5.0, the paper had a detail analysis on the support resuhs of the mining gateway, The resuhs showed that the combined support technology applied to the mining gateway was rational, the main technical parameters selected were safety and the support model and the main technical parameters could be the references to the mine with the similar conditions.
