据苏联黑色冶金工业部矿业学院资料介绍,露天开采深度每增加100米,采1吨矿石的成本就增加0.13～0.57卢布,因此,有必要寻求新的露天开采工艺,使之不仅能够最高效地采矿,还要以最少的人力和最低的费用通过最简捷的途径把采掘物运到地面上来。奥列涅果尔露天矿开采27年共降深了200米。因开采深度大,所以近年来曾经采用联合运输方式往选矿厂运送矿石,即先用 According to the information from the Mining Institute of the Soviet Union’s Black Metallurgical Industry, the cost of mining 1 ton of ore increases by 0.13 to 0.57 rubles for every 100 meters of open pit mining. Therefore, it is necessary to seek for a new open-pit mining process so that not only the most efficient Mining, but also with the least manpower and the lowest cost by the most convenient way to carry the extractives to the ground up. Orenel Güell open pit mining 27 years a total reduction of 200 meters. Due to the exploitation of a large depth, so in recent years have been used to transport ore to ore dressing plant, that is to use
