Abstract
Aiming at the problems of large peripheral rock deformation,high in-situ stress and serious soft cracking of rock layer in deep soft rock roadway,the transportation roadway in No.23601 Face of Guandi Mine was taken as the background of the project.Deformation and damage characteristics of the roadway were analyzed,and the reasons for the deformation and damage in deep soft rock roadway were the large depth of the roadway,low strength of the peripheral rock and the original support scheme through on-site investigation.On the basis,the original support scheme was optimized.The results showed that the maximum deformation of the roof,bottom plate and both sides of the roadway was 138mm,79mm and 114mm respectively,and the deformation of the surrounding rock was effectively controlled.关键词
