摘　　要： 应用联合支护提高巷道围岩稳定性理论,对已有支护参数和支护形式进行优化,支护参数主要包括锚杆直径、长度、间排距和锚索的间距。采用优化支护方案进行支护后,不仅有效控制了巷道围岩的变形,而且大大降低了支护成本,避免了支护材料浪费,提高了企业经济效益。 By using the theory of the combined support to improve the stability of surrounding rocks,the existing support parameters and support form were optimized. The support parameters mainly include bolt diameter,bolt length,bolts space and anchors space. By using the optimized scheme,it not only effectively controlled the deformation of surrounding rocks,but also reduced the cost, avoided the waste of the support materials and improved the economic efficiency of the enterprise.
