Analysis and prediction of rock burst tendency and rock burst grade in deep rock mass of Beijie Gold Mine

In the process of deep mining, geological disasters such as rock-burst may occur due to high ground stress and disturbance.In order to ensure the safe production of deep mining in Beijie mining area, uniaxial and triaxial compression tests of deep rock mass are carried out, on-site crustal stress measurements are carried out, the relationship between crustal stress and burial depth is analyzed, the regression curve between burial depth and crustal stress in Beijie mining area is obtained, the rock-burst tendency and grade of deep rock mass in Beijie mining area are discussed, and engineering suggestions for rock-burst prevention and control are put forward.
