Inducement of rock burst-self-organized criticality character of energy accumulation and dissipation

LU Cai-ping, DOU Lin-ming, WU Xing-rong (The Key Laboratory of Mining and Safety of National Ministry of Education, China University of Mining and Technology, Xuzhou 221008, China; Sanhejian Coal Mine, Xuzhou Coal Mining Group, Xuzhou 221613, China)  
In view of the energy accumulation having the self-organized character of the dissipation structure, aaccording to the mutation theory, as long as energy accumulation keeps a dynamic equilibrium with dissipation in coal body, the energy stored can maintain a certain normal level, from the point of view of micro damage, fracture mechanics, the medium of energy accumulation and dissipation-micro defect(fissure, hole,etc) would not rupture unsteadily to cause impact. That energy accumulation and dissipation in coal body have self-organized criticality (soc) character through theory research and practice, so the rate of energy accumulation can be controlled by the rate of dissipation, and the energy releasing result can be examined by intensity (amplitude) of the electromagnetic radiation (EMR). Making the rate of energy accumulation keep the dynamic equilibrium with the rate of energy dissipation can realize the dynamic prevention of rock burst.
