Working parts of means of minerals excavation

The following article provides a classification of minerals winning equipment along with its working parts. In this classification, we introduce two groups based on two operation principles that are of cyclic and continuous action. The classification further includes three transmission types: hydraulic, mechanic, and combined. Winning machines are further differentiated by chassis type: wheel, screw, and rail drive walking chassis, hull and bridge positioning, rope hauling, and combined chassis types. Six groups of working bodies are introduced, including face (back) shovel, rotor, chain conveyor, dragline, scraper, and combined. Each working body can be active or passive. We also performed an analysis of various buckets and arms that resulted in determining specific requirements for buckets. In this article, we also included descriptions of modern and specialized minerals winning machines and also provided examples of their special field operations. The article refers to all the mining equipment included in the classification with an eye to a problem of moisturized materials mining that results from inundated working faces.
