Abstract: Through the analysis of the deformation and failure of the deep roadway made based on Jinchuan's reality, it was considered that anchor cable support should be used for Jinchun's deep roadway and great importance should be attached to the floor control. In light of the specific conditions of No. 1178 section of the deep roadway in Jinchuan No. 2 mine area and based on the Jinchuan's previous experience in support, several support schemes were proposed, for each of which, numerical simulation was made using 3D FEM software. Through their comparison and analysis, it was concluded that a support method consisting of bolt-spray with wire mesh + anchor cable + floor bolt could basically keep the roadway stable. However, the real stability of the roadway remains to be monitored.
