Technology and Practice of Joint Reinforcement of Deep High Stress Soft Rock Roadway Floor |
| |
Abstract: | Abstract: In order to solve the problem of bottom plate deformation in deep soft rock roadway, Chen Silou coal mine proposed a grouting + anchor + anchor cable reinforcement technology. In this paper, combined with the reinforcement construction process of the pump room and the substation floor in the No. 9 mining area of the Chensilou coal mine, the bottom drum deformation mechanism, the principle of joint reinforcement, and the construction method were analyzed and introduced in detail. The observation results indicate that the floor drum phenomenon in the pumping room and substation of the No. 9 mining area has been well controlled, providing a technical reference for future similar projects. |
