Abstract: Based on the research of prevention techniques on the deep island coal pillar coal bump, a theoretical framework for the prevention and control of high energy rock burst with a defects group is established. The mechanism of apply the engineering and the fracturing defect to prevent and control the rock burst is revealed by the numerical simulation and mechanical analysis. On this basis，the prevention and control of rock burst with a imperfection group measures used in T1391 working face in Tangshan mine in Kailuan，it could validly change the impact energy release law of coal seam and avoid the occurrence of rock burst accidents, and ultimately ensure the safety of working face mining.
