为了探索小型矿山的机械化生产,我们于1984年10月到瑞典考察了波立登公司的霍恩脱拉斯克矿(Horn tra＂sk Mine),这是一个机械化程度高、生产工艺简单的矿山,很值得我们在开发新的边远地区的中小富矿时参考。该矿从1981年开始建设,1982年投产,第一年采出矿石3万吨,现已达到年产矿石10万吨的规模。霍恩脱拉斯克矿为角砾岩型锌、银、铜矿床。矿区分为东西两部:西部由两条平行的锌矿脉组成;东部矿脉为铜锌,矿体倾角大约为30°。现已开拓出的矿量为26.5万吨,其中锌矿量21.5万吨,铜矿5万吨,地质品
In order to explore the mechanized production of small mines, we went to Sweden in October 1984 to inspect the Bornholm Horn trasksk mine, a very mechanized and simple-producing mine, It is worth our reference when developing new small and medium-sized rich mines in remote areas, which started construction in 1981 and put into operation in 1982 and produced 30,000 tons of ore in the first year and now has an annual output of 100,000 tons of ore. The Abrasives Mine is a breccia-type zinc, silver and copper deposit, which is divided into two parts: the west consists of two parallel zinc ore veins, the eastern ore vein is copper-zinc and the ore body dip is about 30 ° Open up the amount of 265,000 tons of ore, of which 215,000 tons of zinc ore, copper 50,000 tons, geological products
