Abstract.
The vertical shafts of msne enterprises behave to the basic workkings, which are counted on all work term of mine and on the period of its deriving from exploitation. For direction of motion of cages they equips by equipment of different types. In the work, advantages and disadvantages of existing shaft equipment were investigated and analyzed, ways of their improvement were defined, and a new design was developed on the basis of rope-profile guides and console-damping shaft buntons and their discrete layout. Introduction of these designs of cable-profile equipment will significantly reduce drawbacks of the existing rigid, flexible, console equipment and will: ensure higher speed and greater hoisting capacity of the cages; prolong the equipment overhaul life; cut capital costs of the construction due to the smaller diameter of the shaft (in comparison with flexible shaft equipment); reduce labour content in the maintenance and repair works; significantly decrease metal consumption in comparison with rigid shaft equipment; decrease level of dynamic oscillations of the «cage-shaft equipment» system; improve damping properties of the shaft equipment due to the increased number of dampers in console shaft buntons and improved properties of the ropes; reduce aerodynamic resistance of the shaft to the level comparable with flexible shaft equipment; improve reliability and safety of the shaft equipment operation; exclude use of balance ropes; apply more rational schemes of the floors layout, which allow using more powerfull cages in the shaft; prolong service life of the guides to the level comparable with service life of the rigid shaft equipment. As is obvious from results of calculations, the rope-profile equipment have less specific quantity of metal as compared to hard one almost in 2 times, and only on 16.5% exceed on specific quantity of metal of flexible equipment.
Development and implementation of the cable-profile shaft equipment will ensure increase of the shaft hoisting capacity and of the hoisting complex as a whole.
Key words: mine vertical shafts, cable-profile guides, skips, shaft buntons, tensioning devices, steel (composite) ropes.
