Impact of the number of blades of the geokhod cutting body on the energy intensity of the rock destruction

Abstract

Abstract The article presents the sequence of calculating the energy intensity of the rock destruction with the blade of the geokhod cutting body. The influence of the number of cutting elements of the geokhod body on the energy intensity of rock destruction is determined. To substantiate the relevance of the study, features of the new class of mining machines – geokhods and the main provisions of geokhod technology are presented. The main research stages are formulated, based on the method for determining the energy intensity of the destruction of the rock face with the blade of the geokhod body. Geometrical features and power parameters of the geokhod blade cutting body that affect the energy intensity of rock destruction are identified. To determine the influence of the number of blades of the geokhod body on the energy intensity of the destruction of the rock face, the geometrical parameters of the blade body and the parameters of the mining and technical conditions of the mine working are substantiated. For carrying out mathematical calculations, an algorithm has been developed for calculating the energy intensity of the destruction of a rock face with a blade body a geokhod. As a result of the study, it was revealed that the energy intensity of the destruction of rock with the blade cutting body increases unevenly with increasing number of blades.
