In order to ensure the cage directed motion, vertical shafts are reinforced with the shaft equipment of various designs: rigid, flexible, with no buntons, rope-profile. In this research, different existing design schemes of the shaft equipment, their advantages and disadvantages, design solutions with the rope-profile guides and discrete step of the shaft equipment installation between the tiers in the point of the cages meeting are considered and studied. Designing, research and installation of discrete reinforcing equipment with the rope-profile guides in the shafts in the point of the cages meeting can significantly diminish disadvantages of the existing (rigid and flexible) reinforcing equipment and can facilitate:  to reduce the number of tiers arranged along the full depth of the shaft; to prolong trouble-free life;  to cut capital construction costs due to less diameter of the shaft (for flexible shaft equipment);  to make maintenance and repair essentially simpler; to reduce significantly metal content of the shaft equipment as  compared to rigid shaft equipment; to reduce dynamic vibrations of the “cage-shaft equipment” system;  to improve damping properties of the shaft equipment; to reduce the shaft aerodynamic resistance to the level of flexible shaft equipment; to improve reliability and safety of the shaft equipment operation;  to eliminate the need to use balance ropes;  to prolong life of the rope-profile guides to the level of rigid guides.

The research and development of these structures and schemes are resulted in: improved reliability and durability of vertical shaft equipment and increased profitability of minerals extraction from deeper horizons. Introduction of the schemes with discrete step of reinforcing equipment installation in the point of cages meeting (in the middle of the shaft) for different locations of the tiers will significantly improve safety of vertical shaft equipment operation and the hoisting complex as a whole.

Keywords:
