Deformation And Failure Mechanism And Repair Technology For Soft Rock Drifts Influenced By Dynamic Pressure

Take XuTuan coal mines in Huaibei Mining Group South Wing track roadway as engineering background, comprehensive use theoretical analysis, computer simulation and field tests and other means to influence dynamic pressure on soft rock deformation and failure mechanisms and repair techniques of the tunnel more systematic analysis and research. Tested the rock mechanics parameters and the rock secondary stress about the South Wing track roadway, analysis of the South Lane deformation and failure of its causes, though on-site observation of the South Lane affected by mining during the deformation, designed the South Lane's rehabilitation program based on above study, through use numerical simulation software ABAQUS simulation research shows that rehabilitation program designed to effectively control the deformation South Lane, and take field tests conducted in based on this program, field measurement showed that the repair program implementation, the South Lane deformation and deformation rate are effectively controlled, thus show that the design of the repair program effective and feasible, and this program should be applied in similar conditions to promote.Figure [73] table [9] reference [59]...
