炸药在岩体内爆炸时所释放出来的能量是以冲击波高温高压的爆生气体的形式作用于岩体的,整个过程在几个到几十个毫秒的瞬间完成。爆破破岩的机理就是研究岩体在爆炸能作用下发生破碎的原理。由于岩石是一种非均质各向异性介质,加上爆炸作用过程本身的复杂性,使得岩石爆破破岩机理的研究变得困难,因而所提出的各种破岩理论还只能算是假说。
The energy released when the dynamite explodes in the rock body acts on the rock mass in the form of blast-gas of high temperature and high pressure of shock wave, and the whole process is completed in several to tens of milliseconds. The mechanism of blasting rock breaking is to study the principle of rock mass breaking under the action of explosion. Because rock is a heterogeneous anisotropic medium, coupled with the complexity of the explosion process itself, making the rock burst rock breaking mechanism becomes difficult, so the proposed rock breaking theory can only be regarded as a hypothesis.
