Research into an angle of repose of construction and ore materials in designing and development of road-construction and mining machinery and equipment

M.A. Perepelkin

The article contains the analysis of an angle of repose, angle of reposeto angle of internal friction ratio of bulk materials. The author presents the results of research into the particle size distribution dependence of an angle of repose. Tests have been performed with crushed stone produced in the quarry of the Medvezhyi Ruchei ore mine and with copper-nickel ore from the Oktyabrskiy ore mine of the Norilsk industrial area.
