Abstract. Various schemes of vertical shafts equipment providing moving of the cage are considered in the paper in terms of their advantages and disadvantages. Different ways are presented for improving the vertical shaft equipment. A cantilever-damping bunton was designed for stiff and rope-profile equipment, which, thanks to the damping system, essentially reduces vibrations both in frontal and side planes. Implementation of the cantilever-damping buntons can:
- significantly increase reliability of the kinematic connection between the cage and the shaft guides thanks to increased opening of the cage safety guides;
- increase reliability of the shaft equipment operation;
- reduce steel intensity of the shaft equipment by 8-10 times if to compare with the stiff (beamed) shaft equipment, especially for specialized rope-profile guides;
- significantly reduce aerodynamic resistance of the air jet and, accordingly, reduce power consumed by the mine main fan installations throughout the whole operation life of the cage;
- increase lifespan of the shaft equipment thanks to reduced dynamic loads in the system "cage – shaft equipment";
- cut costs of the shaft equipment repair by 8-10 times;
- essentially improve safety operation of vertical shaft equipment which has been worn-out and curved in result of long-term (30-40 years) operation in acting mines of Ukraine, and, consequently, help to escape accidents.
