瑞典矿产资源比较丰富,采矿工业在国民经济中占有重要地位,瑞典的金属矿山绝大部分是地下开采,其中既有世界最大的年产矿石2000万吨的基鲁纳铁矿,也有为数众多的中小型有色矿山。瑞典自本世纪四十年代发明了著名的“瑞典凿岩法”(气腿子和碳化钨合金钎头)以来,地下采矿技术水平一直居世界领先地位。重要的科技成果,五十年代有风动装运机、天井爬罐,六十年代有梭式矿车,七十年代有立爪装载机、浓压凿岩机、小直径柱齿钻头、非电导爆管、乳化炸药,八十年代有快硬水泥卷锚杆、胀管式锚杆和架线—蓄电坑用自卸汽车等。 为了学习和借鉴瑞典的成功经验,1986年8月,笔者随团参观访问了瑞典阿特拉斯
Sweden is rich in mineral resources, mining industry occupies an important position in the national economy, most of Sweden’s metal mines underground mining, including both the world’s largest annual output of 20 million tons of Kiruna iron ore, but also a large number of Small and medium-sized non-ferrous mines. Sweden Since the invention of the famous Swedish Rock Drilling Act (gas legs and tungsten carbide alloy) in the 1940s, the underground mining technology has been the world leader. Important scientific and technological achievements, the fifties wind-powered aircraft, climbing canopy patio, the shuttle car in the 1960s, the 1970s with a claw loader, deep-pressure rock drill, small diameter drill bits, non-conductive pipe burst , Emulsion explosives, eighties with fast hard cement bolt, expanded tube anchor and cable - storage pit dump truck and so on. In order to learn and learn from the successful experience of Sweden, in August 1986, the author visited the delegation visited Atlas, Sweden
