The occurrence condition of mine deep level surrounding rock broken roadway, support and deformation features were analyzed, the expand and repair, bolting grouting reinforcement were put into practice by scientific design, the average displacement amount of two sides surrounding rock was no more than 60 mm, without obvious deformation of roadway, the technology saved the roadway repair cost, ensured the safe mining, the combined support is suitable for deep mine of large ground pressure and soft rock broken roadway, with wide prospect of application.
