Abstract Based on broken surrounding rock crossing fault, large deformation of roadway, with support difficulty, 南一1 mining area water discharge roadway of Gubei Mine was taken as example, roadway crossing fault surrounding rock control technology was studied, the support key of the project was analyzed, with corresponding measures, the surrounding rock control plan was designed. The application of the field showed that the maximum roof--floor convergence was 354 mm, the maximum displacement of the two sides 302 mm, the support effectively controlled the roadway surrounding rock deformation, the safe mining of roadway crossing fault was ensured.
