爆破是露天矿开采过程的一个重要环节,爆破技术的不断完善和水平的提高,对于强化矿山生产,提高钻孔、装载、运输机械设备生产效率,降低成本起着关键作用。而确定台阶装药高度与非装药高度的最佳比例,寻求新的装药结构,以便有效地调节炸药能量分布,控制爆破作用,是当前爆破理论和技术发展上的一个关键课题,为此,冶金部于一九八四年下达“合理深孔填塞参数及装药结构研究”重点研究课题。东北工学院,齐大山铁矿,本钢歪头山铁矿共同开展这一课题的试验研究工作。该项成果通过了冶金工业部专家鉴
Blasting is an important part of the open pit mining process. The continuous improvement and improvement of the blasting technology play a key role in strengthening mine production, improving the production efficiency of drilling, loading and transporting mechanical equipment and reducing the cost. Determining the optimal ratio between the height of step charge and the non-charge height and finding a new charge structure so as to effectively adjust the energy distribution of explosives and control the blasting effect is a key issue in the current blast theory and technology development. , The Ministry of Metallurgical Affairs issued a key research project entitled “Study on Reasonable Parameters of Deep-Hole Packing and Charge Structure” in 1984. Northeast Institute of Technology, Qi Dashan Iron Mine, Benxi Iron Castles Waitoushan jointly carry out the subject of this research work. The results passed the expert review of the Ministry of Metallurgical Industry
