摘要

为解决谢桥煤矿1232(3)工作面回风巷道围岩控制的技术难题与经济合理性问题，运用正交实验方法，以巷道两帮与顶底板收敛量为指标，对不同因素不同水平的正交实验数据进行极差分析，得出锚杆直径与间排距为影响回风巷道围岩控制效果的主要敏感因素。同时，选定技术与经济指标，通过分析各关键因素对围岩控制效果的影响情况得出2组局部优化方案，并借助灰色关联分析方法对不同方案进行综合分析和决策，得出最终优化方案。现场实际应用表明，支护参数优化后巷道围岩变形得到有效控制，技术经济效益显著。

Abstract

To solve the problems about the technology and economic rationality of the surrounding rock control in the air-return gate of 1232(3) face in Xieqiao coal mine

it is concluded that bolt diameter and row spacing are the main sensitive factors that affect the surrounding rock control results of the air-return gate by using orthogonal experiment method to analyze the experiment data of different factors in different levels with the roadway’s sides and roof-to-floor convergence as indexes. Meanwhile

two locally optimization schemes are obtained by analyzing the key factors that affect the surrounding rock control results after taking the techno-economic indicators into consideration. The final optimization scheme is reached by comprehensive analysis and decision-making of the two schemes according to the method of grey correlation analysis. The actual application shows that the deformation of surrounding rock of roadway is controlled effectively and the techno-economic benefit is remarkable after the optimization of the support parameters.
