摘　　要：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 researches on blasthok pattern parameters,charge structure, detonating system and so on in Mingchen Limestone Mine, the advanced blasting technology has been developed. By using which the limestone fragmentation was effectivelly controlled and obviously improved, thepowder factor was decreaed.
