通过对明城石灰石矿爆破孔网参数、装药结构、起爆方式的试验研究，采用了先进的爆破技术，有效地控制了爆破粒度，使石灰石矿块粒度明显的提高．降低了单位炸药消耗量．
Based on the experimental study of blasting hole network parameters, charge structure and initiation method of limestone mine in Mingcheng, advanced blasting technology was adopted to effectively control the particle size of blasting so that the particle size of limestone ore blocks was obviously improved. Reduce unit explosives consumption.
