According to problems of low stability and difficult maintenance in the soft rock roadway of Gangli Mine,the roadway support scheme was studied.With the guidance of the rock supporting theory,the deformation and destruction mechanism of the surrounding rock in the soft rock roadway was discussed.By means of the physical simulation experiment and the numerical simulation experiment,the variation law of stress and strain of roadway surrounding rock under different support conditions was studied.The supporting technique and supporting scheme suitable for the engineering characteristics were put forward.The industrial test results show that the deformation and failure of the soft rock roadway were effectively reduced by using the supporting scheme.The good effects to control the deformation of the surrounding rock in roadway were obtained.
