中国矿山工程

A 60 million tons/a scale mine abroad is located in an inland area. The ore body is narrow and far from the mineral processing industry site, with steep terrain and natural slopes. The transportation of ore in this project is characterized by high volume, long distance, and high difficulty in transportation. For large-scale mines, belt conveyors play an extremely important role in the production process due to their advantages of large transportation capacity, long-distance transportation, high degree of automation, and the ability to achieve continuous transportation. At the same time, due to the increasing distance required for conveying, single section of belt conveyor is difficult to meet the overall requirements of bulk material transportation in mines. Belt conveyor systems with large capacity and large angle relay transportation are widely used. This article draws on the production data of the system of existing mining belt conveyor to analyze and calculate the reliability and energy consumption of the belt conveyors system against the background of this large mine, providing reference for similar projects.
