根据俄罗斯大型金属露天矿生产现状指出:传统运输方式──铁路和自卸汽车运输造成生态环境恶化、大气污染以及经济指标变坏等一系列后果,已不适应深凹露天矿生产要求。因此迫切需要探索新的换代运输方式。而大倾角压带式输送机可能就是解决深凹露天矿矿岩提升运输的最有效方式。文章简要介绍:保证压带式输送机正常运输必须满足的条件;基本参数的选择依据以及装载区段和曲线过渡段的结构原理与特征。归纳了具有附加压紧装置的压带式输送机的一系列优点及其在露天矿的应用前景。重点叙述了大陆输送机设备公司生产的大倾角压带式输送机的性能,在世界生产实践中的应用实例以及该公司开发的新颖组合式输送机的特点。文章最后指出在俄罗斯推广应用大倾角压带式输送机的途径。
According to the current situation of the production of large-scale metal open-pit mines in Russia, the series of consequences of the traditional modes of transport ─ ─ deterioration of the ecological environment caused by the transport of railways and dump trucks, the air pollution and the deterioration of economic indicators, are no longer suitable for the production requirements of deep open-pit mines. There is an urgent need to explore new modes of transport. The large angle pressure belt conveyor may be the solution to solve the deep open pit mine rock transport the most effective way. Brief introduction of the article: the conditions that must be met to ensure the normal transportation of the belt conveyor; the selection basis of the basic parameters and the structural principle and characteristics of the loading section and the curve transition section. Summarized a series of advantages of pressure belt conveyor with additional pressing device and its application prospect in surface mine. It mainly describes the performance of large-angle belt conveyor produced by Continental Conveyor Equipment Company, application examples in world production practice and the characteristics of the novel combined conveyor developed by the company. Finally, the article points out the way to popularize the application of large-angle pressure belt conveyor in Russia.
