沿革奥钢联-阿尔平矿业公司(Voest-Alpine)的施泰里舍尔(Steirischer)铁矿位于奥地利中部(莱奥本以北数十公里)。该矿从3世纪罗马帝国时代就开始开采,现在仍能见到当时开采的迹象。以后,从中世纪到19世纪前半期,矿山仍兴盛发达。自19世纪末至20世纪,开始以企业形式进行开采。1974年,年采矿量达到最高纪录376万t。目前采掘总量为1230万t,其中铁矿石230万t,废石1000万t,回采率23％。地质、矿体、矿石该矿地质和矿体情况见下图。
Evolution The Steierischer iron ore mine of Voest-Alpine is located in central Austria (tens of kilometers north of Leoben). The mine started mining from the third century, the Roman Empire, and now there are still signs of exploitation at that time. Since then, from the Middle Ages to the first half of the 19th century, the mines are still flourishing. From the late 19th century to the 20th century, mining began as a business enterprise. In 1974, the annual mining volume reached the highest record of 3.76 million tons. At present, the total volume of mining is 12.3 million tons, of which 2.3 million tons of iron ore, 10 million tons of waste rock, recovery rate of 23%.
