能量积累与消耗是岩爆机理研究的重要内容之一。本文从地应力作用和晶体结构断裂两方面对其进行分析,得出地应力作用对岩爆能量积累来说是一个长期潜在的过程,而从岩石裂纹瞬时扩展及裂纹两侧矿物晶体拉伸破坏角度讲,岩爆能量的积累过程则是短暂的、瞬时的。岩爆释放的能量转化为表面能、动能及热能等形式。控制动能所占比例对防治岩爆或降低岩爆烈度有重要意义。
Energy accumulation and depletion are one of the important contents of the research on rockburst mechanism. In this paper, we analyze the geostress and the fracture of the crystal structure, and find that the effect of the geostress is a long-term potential process for rockburst energy accumulation. However, from the instantaneous extension of the rock crack and the tensile fracture of mineral crystals on both sides of the crack From the angle of speaking, the buildup of rockburst energy is transient and transient. The energy released by rock burst transforms into the form of surface energy, kinetic energy and heat energy. Controlling the proportion of kinetic energy plays an important role in controlling rockburst or reducing rockburst intensity.
