Abstract
The method of work is significant to the nature and approximation of the empirical supply of feedstock energy consumption for the transport of dry waste by a string conveyor, which operates in the drains of the DolzhanskaKapitalna mine, due to the speed of transport of waste. Significant energy consumption for transporting goods is an unknown warehouse assessment of the technical level of the stitch conveyor, which is a current scientific and practical requirement. The article examines the non-linear nature of the dependence of weighted average specific energy consumption for the transportation of bulk cargo by a mine belt conveyor on the speed of cargo transportation. The function of the weighted average specific energy consumption for the transportation of bulk cargo by a belt conveyor is obtained in a theoretical way using the method of technological calculation of a mine belt conveyor. The influence of the unevenness of the cargo flow on the conveyor on the formation of weighted average specific energy consumption was carried out empirically using the results of studies of the cargo flow and the power consumption of the belt conveyor of the "Dolzhanska-Capitalna" mine, conducted in 2011 by the "Dongiprovuglemash" institute. Using the method of least squares, empirical coefficients of the approximated dependence of the weighted average specific energy consumption for the transportation of bulk cargo by a belt conveyor of a mining enterprise on the speed of cargo transportation, which has the form of a square trinomial, were obtained. The results of the work can be determined by designing the conveyor transport of mining enterprises, determining the energy intensity and technical level of the mine stitch conveyor, and clarifying the nature of the mechanical characteristics of the stitch conveyor
