In this paper , charge calculating formulas and their relations of cutting chamber loose blasting are firstly analyzed with the theories of dimension , fluid dynamics . explosive dynamics , etc and the significance of the explosive factor in it is pointed out . calculating methods of the explosive factor are researched by law of conservation of energy , and then a new one is brought forward which proves to be rational and reliable by a sample
本文首先采用量纲分析、流体动力学、功能平衡理论、爆炸动力学等理论，分析了路堑硐室松动爆破装药量计算公式及其内在联系，并指出k值在现有药量计算公式中的重要性；在分析现有k缺陷的基础上，利用能量守恒原理，研究了路堑硐室松动爆破单位炸药消耗量计算方法，并提出一种新的k值计算方法，实例验证本方法合理、可靠，优于其它k值计算方法。
