瑞典采矿研究基金会在基律纳卢萨瓦拉矿进行的一项试验,共采出矿石150万吨。研究试验时间从1981年至1985年,耗资1650万美元。因财政紧张未能完成全部任务。试验研究的目的是:(1)设计一种新的、工作条件更好的有效采矿方法;(2)加强与设备制造厂的合作;(3)根据大直径深孔爆破空场法的岩石力学分析和稳定性控制,研究有关开采原理;(4)改进爆破技术,提高破碎质量;(5)改进锚索支护
A test conducted by the Swedish Mining Research Foundation at the Luwaawala mine in Kiruna produced 1.5 million tonnes of ore. Research test time from 1981 to 1985, cost 16,500,000 US dollars. Due to financial constraints failed to complete all tasks. The purpose of the pilot study is to: (1) design a new effective mining method with better working conditions; (2) strengthen cooperation with the equipment manufacturer; and (3) rock mechanics based on the large-diameter deep- Analysis and stability control, research on the mining principle; (4) to improve the blasting technology to improve the quality of crushing; (5) to improve the cable support
