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.
