摘要
本文根据近代已经基本搞清的煤岩变形破裂理论探讨了冲击地压和突出现象的共同机理。作者指出:冲击地压和突出都是煤(岩)变形系统处于非稳定平衡状态下受到扰动发生的动力失稳过程。采用失稳的能量判据作为冲击地压和突出的统一判据,建立了这两种现象统一的失稳理论。
In this paper the authors discuss the common mechanism of coal/rock burst and outburst based on theory of deformation and crack of coal/rock which is basically established in modern times. The authors put forward that coal/rock burst and outburst are dynamic instable processes induced by mini-disturbance when the equilibrium of deformation system of coal/rock is unstable. The unstable energy criterion is used as a united criterion for occurrence of coal/rock burst and outburst. The authors have established a united instability theory to explain these phenomena.
