近年来,人们采用多种方法选择与给定岩石条件相匹配的炸药。在这些方法中,有的是基于对炸药所含能量的考虑,有的是基于炸药爆炸气体能与应变能的相对分配,而另一些则基于现场爆破漏斗试验并考虑岩石对破碎作用的阻力。 In recent years, people have used a variety of methods to select explosives that match given rock conditions. Some of these methods are based on the consideration of the energy contained in the explosive, some based on the relative distribution of the energy of the explosive’s explosive gas to the strain energy, while others are based on the field blast funnel test and consider the resistance of the rock to crushing.
