由北京科技大学采矿系方祖烈、丁钦贡等人研究设计的一种地下采矿新方法——垂直束状炮孔崩落法,最近在邯邢矿山局西石门铁矿全面推广应用。该项成果为冶金部“七五”科技攻关项目,曾获得1991年度冶金部重大科技成果奖,有关专家认为,此种采矿方法属国内首创,并达到国际先进水平,为我国大量缓倾斜、中厚以上低价矿体的开采,提供了一条低成本、高效的开采途径,经济效益和社会效益显著,推广应用前景十分广阔。
A new underground mining method, the vertical bunched-hole blasting method, was researched and designed by Fang Zu-Lie, Ding Qin-Gong and others from the Department of Mining, University of Science and Technology Beijing. It was recently widely applied in the West Sheimen Iron Mine in Handan Mining Bureau. This achievement was awarded as the “Seventh Five-Year” scientific and technological project by the Ministry of Metallurgy and won a major scientific and technological achievement award of the Ministry of Metallurgy in 1991. According to relevant experts, this mining method belongs to the first domestic initiative and has reached the international advanced level. The exploitation of low-priced ore body above the thickest provides a low-cost and efficient mining method with significant economic and social benefits and a promising prospect for application.
