摘　　要：针对木瓜矿现有南区左翼下组煤回风巷道复杂的地质情况,结合矿井地质概况和水文地质条件,分析了现有支护形式存在的不足,利用巷道支护形式和参数选择原则,对巷道锚杆长度、间距、角度以及预应力等支护参数进行了选取,并结合支护参数对巷道支护进行了优化设计,应用结果表明,巷道变形在允许变形的范围内。In view of the complex geological condition of the support of the air return roadway of the left-wing southern part of the Mugua Mine,combined with the geological profile of the mine and the hydrogeological conditions,the existing shortages of the existing support forms were analyzed,and the form and parameter selection of the roadway support were used.In principle,the support parameters such as length,spacing,angle and prestress of the roadway bolt were selected,and the roadway support was optimized with the support parameters.The application results showed that the roadway deformation was within the allowable deformation range.
