摘　　要：为解决厚泥岩顶板巷道围岩变形严重且不易控制的难题,以霍州煤电紫晟煤业2-101回采巷为背景,综合理论分析、现场实测、支护优化的方法,分析了厚泥岩顶板巷道围岩变形特征与变形原因,对2-101回采巷支护参数进行了优化。结果表明:围岩变形特征表现为顶板下沉严重、支护体失效、围岩流变性大;围岩变形主要原因为地质条件复杂、支护体承载力不足、顶板下位岩层破坏。In order to solve the problem that the surrounding rock deformation of thick mudstone roof road is serious and difficult to control,the method of comprehensive theoretical analysis, field measurement and support optimization is analyzed based on the 2-101 mining roadway of Huozhou Coal Mine Ziyan Coal Industry. The deformation characteristics and deformation causes of surrounding rock in thick mudstone roof roadway are optimized for the support parameters of 2-101 mining roadway. The results show that the deformation characteristics of surrounding rock are characterized by severe roof subsidence, failure of supporting body and large rheology of surrounding rock. The main reasons for the deformation of surrounding rock are complex geological conditions, insufficient bearing capacity of the supporting body and destruction of the lower stratum of the roof.
