Abstract： In view of the increasingly serious problem of soft rock roadway faults, the secondary support form of ' bolt + grouting ' was used to carry out the support work of roadway crossing faults. Firstly, the bolt was arranged at the fault position of the roadway for support, and then the slurry was injected to enhance the support effect. Through the example results, it could be seen that after the construction of the design support technology, the deformation of the surrounding rock of the left side of the roadway passing through the fault was 36.8 mm, and the deformation of the surrounding rock of the right side was 39.3 mm, which achieved the expected support effect and the construction quality was better. It was of great significance to study the support technology of roadway crossing fault under soft rock geological conditions to ensure the safety and smooth progress of coal mining.
