前言静态爆破是一种借助静态爆破剂(以下简称静爆剂)的静力膨胀作用使被爆物体解体破环的爆破方法。它具有无爆声、飞石、冲击波和爆破震动等优点,并可按照要求实现成型成材爆破,提高石材利用率,对石材工业具有重要意义。因此,研究静爆的力学原理,确定合理的爆破参数,对于提高它的技术经济效果非常重要。众所周知,岩石是一种抗拉强度和断裂韧度均很低的材料,只要对它的某些部位(如孔壁)施加一定的膨胀压力,便可使孔壁产生径向张开裂纹,并可由裂纹进一步扩展和相互连结导致岩石解体破坏。笔者认为, Preface Static blasting is a kind of blasting method that breaks down the broken object by means of the static expansion of static blasting agent (hereinafter referred to as static blasting agent). It has no sound explosion, flying stone, shock wave and blasting vibration and other advantages, and in accordance with the requirements of molding blasting, improve stone utilization, the stone industry is of great significance. Therefore, studying the mechanics principle of static explosion and determining the reasonable blasting parameters are very important to improve its technical and economical effect. It is well-known that rock is a kind of material with low tensile strength and fracture toughness. As long as some of its parts (such as the hole wall) exert a certain expansion pressure, the hole wall can generate radial flaw and The cracks can be further expanded and linked to each other and lead to the destruction of the rock. the author thinks,
