Simulation of material flow using vertical transport by a double-action mine hoist

摘要: As one of the logistics processes, the transport process currently has an irreplaceable place in the logistics systems of companies and the supply chain. The common goal of transport, both internal and external, is to satisfy customers' needs, ie move the material at the right time, to the right place and in the required quality with the effective use of means of transport and equipment. In the mining industry, intra-company transport has an important position. In underground operations, various transport systems are used for horizontal transport (mining rail transport, rake and belt conveyors, suspended transport, trackless mining transport, etc.). Vertical transport with a mine hoist is often used in deep mines to transport material from and to the underground. Mine hoisting machines are complex machinery used to raise ore and waste rock and transport personnel, materials and various mining equipment between the mine surface and its underground. A standard hoisting machine consists of a hoist drive, headframe, ropes, conveyances (cages or skips), and control and safety devices.[1] Definitions of the basic concepts of vertical transport are given in several publications [2]. Mine hoist can be categorized from several systemic perspectives. For example, the categorization by the maximum rated velocity: the category of large mine hoist machines with a rated velocity above 3 ms-1 and the category of small hoisting machines with a rated velocity below 3 ms-1. According to the method of transport, we differentiate [3]: A) Single-acting mine hoist. They are characterized by the fact that only one transport container is suspended from the rope. They make it …
