Abstract:To counter to the problems of large deformation, long duration of deformation and high repair rate of the roadways after permanent support in the high-stress soft rock area in Tongchuan Xiujiagou Mine, numerical simulation was made on three support schemes with FLAC3D software based on the analysis of the characteristics of its surrounding rock, the basic features of surrounding rock deformation and destruction of the cross-measures inclined roadway were obtained, the mechanism of its heterogeneous destruction was revealed and the measures for strengthening the floor and controlling the floor heave were put forward, all of these provided a theoretical basis for the support design of the cross-measures inclined roadway in high-stress soft rock area.
