Transport by mine hoisting equipment is used to remove excavated materials, deliver materials, machinery, and equipment required for the mining process and related activities, as well as transport persons. These technological devices use transport containers to pull the load in the form of a skip, cage, or skip-cage from underground to the surface. Mining machines are intended for vertical and inclined pits. Scientific research discussed in the present article focuses on the transport capacity of the mine hoisting...

The present article deals with the issues regarding the impact process at the impact of the material onto an enclosed conveyor belt supported by an impact bed consisting of impact rods at the feeding site. The theory of the impact process is based on the following preconditions: the whole impact process and the related processes are only performed at the impact site; the rock block is of relatively small dimensions compared to the conveyor dimensions; the impact bed is absolutely rigid; the conveyor belt is absolu...

Research discussed in the present article is focused on the determination of the mining rail transport capacity while applying two approaches. The first one - a conventional one, is a calculation of capacity while using known mathematical formulas. The second one - an experimental approach, identifies the capacity on the basis of simulation application, as the simulation has remarkable potential also in terms of further research in the given area. The simulation model was created in EXTENDSim, a product of Imagine...

Mining industry is still the only supplier of mineral resources, both metals, coal and other useful mineral substances. Transportation represents an integral part of the logistics system in each mining company. The most frequently used mineral transportation system is the truck transport. Loading and transportation is important part in the extraction and processing of minerals. The selection of loading and transport means affects the efficiency and performance of the whole operation. A choice of an appropriate loa...

Modelling is the process of replacing the dynamic system of its model. The loading of mineral resources is an integral part of their circulation. The first loading process is being carried out during the excavation of raw materials. Subsequently, the loading process is carried out in the other stages of its transportation by various means of transport or processing. The contribution describes a model example of loading the selected mineral raw material into the selected type of transport means railway wagon. The m...

The conveyor belt as the composite is made of different materials to ensure its required mechanical properties that correspond to the handling characteristics of the transported material. The basic elements of the composite structures are top and bottom cover layer from rubber and carcass with fabric plies. The composite structure - the number and type of fabric plies, the type and thickness of cover layers or the bumpers is designed according to the specific mining conditions. The bumper is designed to absorb the...
