【 摘 要 】

Static friction is one of the most important factors affecting the parameters of technological processes in the mining and metallurgical industries. To obtain reliable results of mathematical and computer simulations, there is a need to estimate a number of physical parameters of materials. With respect to the metallurgical and mining industries, the static friction parameter is of particular importance because of its applicability to relatively common process steps. Evaluation of static friction for bulk materials causes particular difficulties, which is justified by the variability of the particle size distribution, shape and density of particles. This article provides an overview of the existing methods for assessing static friction of bulk substances, their applicability, as well as the development trends of this scientific field.
