Dynamic Analysis of Mining Hoist Operation in Emergency States

In the paper is presented dynamical analysis of operation of the mining hoist facility, which braked in emergency in the area of freepass ways. The mechanical model has substituted the hoist facility, where equations of motion described ropes elements as elastic members with variable length of the parts of supporting rope between the tub braked in the tower and the drive wheel. There are given equations having closed form, which determine displacements of the mass of the upper tub with material, braked in the tower, as the function of the braking force and the motion parameters of the hoist.
