Abstract
Buntons and conductors of shaft equipment during operation are subjected to mechanical wear due to constant force interaction with conveyance and corrosive factors exposure affected by mine environment conditions. During prolonged operation shaft wear caused by these processes is uneven along the length of conductors and bunton beams, as well as within the sections located at different shaft depth. Considering this it is urgent to study the effect of parameters of residual section of metal wear equipment on their strength characteristics during the long-term use. The main causes of equipment wear are significant reversed vertical deflection of conductors, lack of proper effectiveness of the work of roller guide vehicles and corrosion provoked by exposure to aggressive mine environment. Due to lack of standards and measures for technical supervision of buntons mechanically they prove to be most often the weakest unit in the «conductor - bunton» system. The article shows that the wear rates of the conductors in the frontal and profile planes are different and depend on the dynamics of the «vehicle - equipment» system. The research made allows establishing the influence patterns of the geometric parameters of beams and conductors buntons on the equipment strength, which results in a more effective approach to choosing assortment of shaft metal components when carrying out design and repairs.
