Abstract. The paper studies the existing options of rigid reinforcement of vertical shafts, consisting of buntons and guides of various types, which ensure the movement of vehicles in the shaft reinforcement with double-row rope-profile guides. We have considered various layouts and structures of tiers for various number of vehicles moving in the shaft and their purpose (skips, cages, counterweights), and analyzed their advantages and disadvantages. On the basis of analysis and research, the structures of buntons for double-row rope-profile guides and the legs with grips have been developed that allow the guides to move up and down relative to the tier, to transfer horizontal dynamic forces in the frontal and lateral planes. Research, analysis, development and implementation of bunton structures for double-row rope-profile guides and implementation with connecting rods, frames, which provide greater reliability while maintaining all the necessary clearances (according to the Safety Rules) between the vehicles and the shaft lining, in the "vehicle-reinforcement" system. Using the results of these studies in the development of existing structures will achieve the following results: - increasing the safety level while observing the standard clearances in the elements of shaft reinforcement; - reducing capital costs due to a decrease in the metal consumption of the tier of shaft reinforcement; - reducing the labor intensity of maintenance and repair by reducing the number of buntons and their fastening elements; - reducing the effect of clogging and corrosion on the durability of rope-profile guides and buntons; - reducing the impact of shaft lining violation on the reinforcement; - increasing the reliability level of kinematic connection in the "guide-bunton" system; - providing standard clearances in the shaft section at a safe level; - ensuring a high reliability level and safe operation of the shaft reinforcement with rope-profile guides.
The implementation of developed structures of double-row rope-profile guides of the vertical shaft reinforcement will lead to an increase in the level of safe operation, while reducing the metal consumption and the cost of maintenance and operation of the vertical shaft reinforcement.
Keywords: mine vertical shafts, double-row rope-profile guides, skips, cages, counterweights, console buntons, legs for fastening vehicles to guides.
