Abstract. The paper studies the horizontal loads arising from the movement of vehicles under the action of dissipative forces (torsion of ropes, aerodynamic forces, loading cages with eccentricity in the frontal and lateral planes), which act on single-row rope-profile guides (hereinafter referred to as RPGs or guides).
In the paper, for the case of two moving cages of one lifting unit, in accordance with the current regulatory techniques and Safety Rules, shaft cross-sections for various types of shaft reinforcement were designed, their advantages and disadvantages were analyzed, and their comparative analysis was carried out.
On the basis of the research, the structures of single-row RPGs have been developed that have a smaller number of ropes and the structure of an enclosing profile in the form of an elongated hexagon, which makes it possible to increase the reliability of the kinematic link in the "vehicle-guide" system and ensure an increase of safety gaps between the vehicles and the shaft lining.
The development of various structural solutions for single-row RPGs for cages makes it possible to achieve:
- high reliability of a single-row RPG operation;
- increased service life due to a significant decrease in the level of dynamic effects;
- reduced labor intensity of maintenance and operation compared to rigid reinforcement;
- reduced metal consumption compared to rigid reinforcement;
- reduced level of dynamic oscillations at the meeting point of vehicles in the middle part of the shaft by reducing the RPG deflection;
- increased reliability of the kinematic link in the "vehicle–RPG" system due to the use of specially designed guide legs;
- reduced safety gaps per side (- 500 mm per side) for cage hoists along the entire depth of the shaft compared to flexible reinforcement;
- reduced operating costs due to the high service life of a single-row RPG;
- elimination of the use of fender ropes;
- increased service life of rope-profile guides to the level inherent to guides of rigid shaft reinforcement.
The result of the implementation of the developed structures of single-row RPGs with reinforcement is the extension of the service life of the reinforcement, and the reduction in the cost of capital construction and operation in the extraction of minerals from deep horizons.
Keywords: mine vertical shafts, single rope-profile guides, reinforcing guides, increasing the safety gaps between cages and the shaft lining, guiding safety devices, horizontal forces in frontal and lateral directions.
