(一)概述 炸药爆破是当代采矿工程重要的、有时是唯一的手段,如何提高炸药的能量利用,改善炸药的效果,必需引起重视,必需深入研究。本文企图探讨炸药的热工转换,对建立:“能量密度—爆破几何参数—岩体”三位一体的爆破理论系统,从理论上寻求更合理的“能量密度”(即是炸药绝对能或相对能与岩石体积的关系)。提高炸药爆炸有用功的利用率有一定的实际意义。
(I) Overview Explosive blasting is an important and sometimes the only means in contemporary mining engineering. How to improve the energy utilization of explosives and improve the effect of explosives must be emphasized and must be studied in depth. This paper attempts to explore the thermal conversion of explosives, to establish: “energy density - blasting geometric parameters - rock” trinity blasting theory system, in theory to seek more reasonable “energy density” (that is, absolute or relative explosive energy Rock volume). It is of practical significance to increase the usefulness of explosive explosions.
