Methodological principles of equipment selection for cyclical-and-continuous technology mechanization

Authors: Glebov A. V.

Given improvement of open pit mining technologies, as well as mining and haulage equipment, selection of rational structures for mechanization of the cyclical-and-continuous technology and its methodology is a critical task. The implemented research allowed development of the main provisions and recommendations on the choice steps of equipment for crushing, conveying, excavation, loading and scraping operations. The chosen equipment correlation is carried out with regard to the effective on-stream time and the main performance indicator—the hourly efficiency of an equipment unit characterized by the tightest connection of components. The developed action chart ensures optimization of equipment parameters in conveyor lines, and also rational qualitative and quantitative ratio of equipment parameters in contiguous equipment units in the cyclical-and-continuous technology. Using the estimated technical and economic indicators, the nature of change in the capital and operating costs of crushing, conveying, excavation, loading and scraping machines subject to annual productivity and height of conveyor hoisting transport is defined. The methodical principles described in the article can be used to optimize the parameters of equipment in crushing and conveying systems, including high-angle and conventional conveyors, as well as to justify the rational mechanization structures for the cyclical-and-continuous technologies in specific mining conditions.

Keywords: cyclical-and-continuous technology, deep open pits, mining conditions, technical and economic indicators, equipment selection, productivity, crushing-and-conveying system, dump truck.
