To improve the durability of the rollers of supporting and guiding devices as well as traction ropes of ropeway facilities based upon the analysis of their contact interaction. Theoretical studies of a mathematical model of contact interaction of mine ropeway components to determine regularities of the formation of dynamic efforts within the contact area and experimental studies of the plant under mine conditions. Based upon a mathematical model, contact stresses within the zone of contact of traction rope with guiding rollers and drive sheaves of mine ropeways under real operating conditions have been determined. The obtained results are validated experimentally under mine conditions. Innovative patent-protected design solutions have been proposed; the solutions make it possible to considerably increase the durability of the ropeway components. It has been determined that methods of surface increase in the strengthening of a roller working surface do not have proper effect as the strengthened layer on a soft base cracks and delaminates due to high contact loads; maximum angle of rope bending on rollers of supporting devices (6º – in operation manual; 15º – in safety rules) recommended for GRW is overstated. It shouldn’t be more than 1.5º in terms of values of contact stresses for standard plants; development of prestressed compression state in the material of elastic lining of a drive friction sheave allows increasing considerably (by two times and more) its service life. Ropes with reduced diameters of external layer wires (Ukraine’s regulatory document – DST 2688) being used currently on mine ropeways do not meet the operating conditions and have a short period of service life due to their corrosive and fatigue breaking. To lengthen the service life of GRW traction ropes, it is required to change for the ropes with increased diameters of the external layer wires with preliminarily clamped strands.
