针对能量积聚具有耗散结构的自组织性,依据突变理论,只要煤体中能量的积聚与耗散维持一个动态平衡,从而其储存能将始终维持在某一正常水平,从细观损伤、断裂力学的角度来看,煤体中能量积聚与耗散的载体-微缺陷(裂纹、孔洞等)就不会失稳断裂而形成冲击。通过理论研究与现场实测发现煤体中能量的积聚与耗散具有自组织临界性(SOC),因此可以通过煤体中能量的释放率来控制能量的积聚率,并利用电磁辐射强度(幅值)来检验能量释放的效果,使得能量的积聚与耗散维持动态平衡并处于自组织临界值之内,从而实现冲击矿压的动态防治。
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.
