Abstract. In this work, the existing normative methods for maintaining shaft equipment of mine vertical shafts were investigated and methods for maintaining shaft equipment with rope-profile guides, console-damper buntons, tension devices in the sump part of the shaft and in the pile driver were developed. Interrelations of processes: operation - maintenance - repair in the system of mechanisms were investigated for developing decision-making algorithms to determine the actual state and predict the residual life of the elements, on the basis of which the choice of a system for repair and maintenance of equipment is made. This article contains a study of the advantages and disadvantages of existing types of reinforcement and their comparative analysis with cable-profile reinforcement.
The use of this study results in relation to the mine shaft equipment with rope-profile guides (hereinafter – the RPG) will allow:
- to reduce the risk of emergencies;
- to develop an optimal system for carrying out repair and maintenance work;
- to optimize repair and maintenance costs (spare parts, components, labor resources, number of repair personnel, etc.);
– reduced labor intensity of maintenance and operation, compared to rigid reinforcement;
– reduced metal consumption compared to rigid reinforcement;
– increased reliability of the kinematic connection in the "vehicle–RPG" system due to the use of bunton legs with connecting inserts;
– reduced safety gaps per side – 350 mm for skip hoists, and – 500 mm per side for cage hoists along the entire depth of the shaft as for flexible reinforcements;
– exclusion of the use of fender ropes;
– increased service life of rope-profile guides to the level of guides for rigid shaft reinforcement.
Keywords: mine vertical shafts, rope-profile guides, console-damper buntons, technical maintenance, tension extensions, rope production, repair, technical maintenance.
