露天开采斜坡箕斗提升是露天矿联合运输的重要方式之一,也是联合开拓运输的主干。最近10～15年来,随着露天矿延深及其开采技术的发展,资本主义国家特别是美国,加拿大采用斜坡箕斗提升的露天矿越来越多。根据目前收集到的资料统计,全世界范围内(包括国内外在内)已建成有15个露天矿采用斜坡箕斗提升。在国外,特别是西方资本主义国家,斜坡箕斗提升的联合运输方式之所以获得较广泛的应用,其主要的原因是:(1)矿岩的提升距离最短;(2)缩减了扩帮工程量;(3)露天矿运输周期短,工作量少,运输成本低;(4)基本建设投资费用不大;(5)与铁道、汽车运输方式相比,露天
Open-pit slope ramp upgrade is one of the important ways for the joint transport of open-pit mines, as well as the backbone of joint development and transportation. In the recent 10 ~ 15 years, with the deepening of the open-pit mines and the development of its mining technology, more and more open mines are being used in capitalist countries, especially in the United States and Canada, to upgrade with slope skip. According to the statistics collected so far, 15 open pit mines have been built with slope skip upgrades all over the world (including both at home and abroad). The main reasons why the combined mode of transport for slope improvement has been widely used in foreign countries, especially western capitalist countries, are as follows: (1) the shortest lift distance of ore rock; (2) (3) The opencast mine has a short transportation period, less workload and low transportation cost; (4) The capital construction investment is not expensive; (5) Compared with the railway and automobile transportation modes, the open air
