Abstract

Results of the mechanical and mathematical modeling of the movement of a hoist vessel (skip) in underground mines are presented. The numerical solution algorithm of the obtained model is developed using the data derived from the existing system for skip hoist movement smoothness monitoring. The algorithm allows to calculate the impact of skip on the guides, specifically, the horizontal components of the force acting on the guides in the place of their contact with the hoist skip. The guides were evaluated for horizontal deformations as well for potential occurrence of plastic deformations and the momentum of the existing forces acting in the plane perpendicular to vertical axis of the hoist system.
