露天矿采用陡帮开采工艺,目前在我国还没有全面的实践经验,而在国外早已成功地推广应用。为了慎重而又有计划地采用该项先进的采矿技术,冶金部以(82)冶矿字第744号文,指示鞍山冶金矿山设计研究院和长沙黑色冶金矿山设计研究院,分别选定南芬和海南两个生产铁矿山,开展陡帮开采工艺全过程全面的可行性研究。经过两年时间的工 Open-pit mine using steep gang mining technology, at present in our country does not have comprehensive practical experience, and has long been successfully applied in foreign countries. In order to adopt this advanced mining technology carefully and systematically, the Ministry of Metallurgy instructed Anshan Metallurgical Mining Design and Research Institute and Changsha Black Metallurgical Mine Design and Research Institute to take the title of Nanfen And Hainan two iron mines to carry out steep-gang mining process full feasibility study. After two years of work
