摘　　要：针对单侯矿动压巷道应力叠加影响的复杂情况,在现场调研的基础上,分析了单侯矿现有支护存在的问题,研究了采动影响下回采巷道围岩变形特点。采用锚网支护加固原理及锚索支护补强原理,对现有支护参数进行了系统优化,提出了该矿锚网索支护设计方案。通过现场实测表明,采用新的支护方案后,巷道围岩变形显著减小,巷道断面的强烈变形得到有效控制。Based on field investigation,problems of roadway support in the complex situation of stress superposition in Danhou Mine are analyzed and an overall investigation is made on the deformation characteristics of surrounding rock under the influence of mining.In addition,using bolt-mesh strengthening principle and anchor supplement support theory,the bolt-mesh-anchor support parameters are optimized and the design scheme of support is put forward.Field observation results show that the roadway displacement is greatly reduced by using the new support scheme and the intensive deformation of roadway cross-sections is effectively controlled.This method provides a decision support for the selection of reasonable support parameters for mining in 6 coal seam and rationalized roadway support in Danhou mine.
