摘    要:针对山脚树矿21108回风巷支护后产生的变形过大,依据耦合支护技术的设计思想,对山脚树矿21108回风巷现有支护中锚杆、锚索的支护参数进行了优化,计算得到了新的基于耦合支护技术的合理支护方案,并通过数值模拟的方法对优化方案及原始方案进行对比分析.研究结果表明:耦合支护设计不但有利于围岩的稳定,同时可以改善岩体的自身承载能力,优化后的合理支护方案比原方案的支护效果要好,巷道变形得到有效控制.

关 键 词:煤巷  耦合支护  参数优化  设计

Abstract:In allusion to the large variant after supporting in the return gateway of 21108 in Shan Jiaoshu Mine, according to the design idea of coupling support, the existing supporting parameters were improved, the reasonable supporting proposal was gotten, which based on the coupling support technology, and the optimum proposal was contrast with the primary proposal through numerical simulation. The consequence indicate that not only designing method of coupling support is in favor of surrounding stable, but also this method improve the carrying capacity of surrounding rock, and the optimum proposal is better than the primary proposal ,and the optimum proposal effectively control the variant of surrounding rock.
Keywords:coal tunnel  coupling support  parameter improving  design
