Vertical shafts are the basic workings in the mine as through them cargoes and minerals are hoisted, roadways are ventilated, water is pumped out, power and communication cables are laid, fire pipelines, emergency stairwells are installed, etc. The main lifting vessels are driven by the hoist engines installed in the headgears, which can be mine headgears or surface headgears. For the directed motion of the vessels and their unloading, modern headgears are equipped with the rigid and flexible shaft equipment; flexible equipment needs additionally the rigid one. Various structures for rope-profile guides fastening providing directional movement of the vessel along the length of the mine headgear were investigated, and shortcomings and advantages of the existing methods for fastening the guides with the flexible and rigid shaft equipment were revealed. As a result of the research, highly reliable and highly efficient fastening structures were designed, which allow to use them for directional motion of vessels in the rope-profile guides (RPG) of the mine headgears. Research, development and introduction into production of new designs of fastening the ropes of the RPG in several sites located at different levels in the headgear and being reinforced by the structures in the shape of trusses and racks will allow, with the help of guide pulleys, thimbles and safety lifters: to exclude duplication of rigid shaft equipment in the headgear, except for the guide curves; reduce dynamic load transmitted to the headgear through one section; to increase reliability of fastening of each of the RPGs at several levels in the headgear; to reduce effect of the tilting moment on the headgear caused by moving vessels and the shaft equipment; to increase trouble-free life of the headgear structures; to increase free access to equipment for its easier maintenance; to improve reliability of the headgear equipment; to increase rigidity of the floor structures by using racks and trusses between the adjacent sites for the RPG rope tightening in the headgear; to reduce metal consumption for the headgear equipment.

Keywords: mine vertical shaft, rope-profile guides, lifting vessels, mine headgears, structures for fastening guides in the headgear
