近年来,陡帮开采工艺在我国采矿界引起广泛重视,并在汽车运输露天矿山开展了一些陡帮开采研究工作,取得了一定的进展。但对铁路运输陡帮开采,在我国尚无实践经验。为了研究和论证铁路运输露天矿采用陡帮开采在技术上的可行性和可能获得的经济效果,我们于1981年开始,以大孤山铁矿为实例开展丁该项研究工作,历时四年时间先后完成了陡帮开采 In recent years, the steep-gang mining technology has drawn wide attention in China’s mining industry. Some steep-gang mining research work has been carried out in the open pit mined cars and some progress has been made. However, for the steep mining of railway transportation, there is no practical experience in our country. In order to study and demonstrate the technical feasibility and possible economic effects of steep-gang mining using open-pit mines, we started this research work in 1981 with Dagushan Iron Mines taking four years Has completed a steep to help mining
