岩爆过程的能量分析

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。

Analysis of Energy Released in Process of Rock-burst

Accumulation and dissipation of energy is one of the important problems about the mechanisms of rock-burst.Form the ground stress and the tensile fracture of microscopic crystals this paper makes an analysis and comes to a conclusion,that the energy accumulation in the process of rock-burst,the ground stress process is long and potentially period.But,from the view of the tensile fracture of microscopic crystals in rocks,it is put forward that the accumulation process of energy in the process of rock-burst is very transient.The energy in the process of rock-burst turns into surface energy,kinetic energy and heat energy and so on.How to control the proportion of kinetic energy is important to prevent rock-burst or reduce its intensity.
