| Abstract: | In combination with the practice that the isolated old pillars at level-250m in Cheng Zi mine are extracted out, the paper discusses some problems about measures of prevention and remedy of rock-burst, such as choosing reasonable engineering plan, unloading blas and unloading drilling before mining coal sems and avoiding peak value of stress in coal seam for driving headings, etc. |
