由齐大山铁矿负责,鞍钢矿山公司研究所、东北工学院、鞍钢矿山公司科技处、青岛冶金矿山大学和鞍钢矿山公司设计院参加并完成的“15m台阶开采技术研究”,是“凹陷露天矿开采技术研究”的一个子项。这项攻关试验研究取得如下成果: 1.15m台阶开采同齐大山铁矿(及我国绝大多数冶金露天矿山)目前的装备水平相适应,工业性试验采用的各项生产工艺技术是可行的。 2.所采用行之有效的控制爆堆高度的综合技术措施,确保了4m~3电铲开采 The “15m Bench-top Mining Technology Research”, which is undertaken by Qi Dashan Iron Mine, Ansteel Mining Research Institute, Northeast Institute of Technology, Ansteel Mining Company Technology Department, Qingdao Metallurgical Mining University and Ansteel Mining Company Design Institute, is the project of “ Mining Technology Research ”a sub-item. This research has achieved the following results: 1.15m bench-top mining is compatible with the current equipment of the Qidashan Iron Mine (and the vast majority of China’s open-pit mines), and the various production techniques used in the industrial tests are feasible. 2. The comprehensive and effective technical measures adopted to control the height of the explosive heap ensure that the 4m ~ 3 electric shovel mining
