Based on the comprehensive investigation and study of rock burst, the prevention and control of rock burst and its development trend are analyzed. The engineering defect prevention and control methods with high stress and high energy rock burst are put forward. According to the engineering characteristics of the rock burst coal seam, the definition and classification of the defects were discussed. The mechanical mechanism of the prevention and control of the rock burst by engineering defects was expounded in detail. The stress distribution characteristics of the coal seam with the damaged medium were analyzed. The mechanism and application of rock burst prevention and control are expounded in detail. The range and degree of energy release of the defect are verified by numerical simulation. Some results are obtained in the aspect of rockburst control in deep and strong impact energy regions.
