炮孔填塞和装药结构是调节炸药能量分布和爆炸作用时间的有效途径。为此,冶金工业部于一九八四年下达了“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、鞍钢矿山公司齐大山铁矿、本钢歪头山铁矿共同开展这一课题的试验研究工作,经过三年多努力研究实现了预期目的,取得了显著的技术成果和经济效益。近日,该项成果通过冶金部专家级鉴定。
Blast hole filling and charge structure is an effective way to adjust the explosive energy distribution and the explosive action time. To this end, the Ministry of Metallurgical Industry issued in 1984 a “key issue of research on rational deep-hole packing parameters and charge structure”. Northeast Institute of Technology, Anshan Iron and Steel Company Qidashan Iron Mine, Benxi Iron and Steel Waituoshan iron mine jointly carry out the pilot study of this issue, after more than three years of hard work to achieve the desired goal, and achieved significant technological achievements and economic benefits. Recently, the results through the metallurgical experts identified.
