坑道掘进中计算裝藥量的公式,直到现在还是采用按爆破岩石的体积来计算裝藥量。这一类的公式虽然具有不同的形式,但是基本論点都是一样,仅是有些校正系数不同而已。近几年来,苏联学者們通过试驗和理论研究,获得了裝藥量計算的新理论,指出了在爆破时,不仅要克服破碎岩石的重力(即旧理論所指的岩石体积),同时还要克服岩石破裂面上的粘结力,換言之,克服
The formula for calculating the charge in tunneling has until now been used to calculate the charge by the volume of blasting rock. Although this type of formula has different forms, but the basic argument is the same, only some of the correction coefficient is different. In recent years, Soviet scholars have obtained new theories of charge calculation through experimental and theoretical studies, pointing out that not only the gravitational force of broken rock (that is, the rock volume referred to in the old theory) must be overcome during the blasting, but also Overcoming the cohesion on the rock’s ruptured surface, in other words, overcoming it
