Abstract. Conveyor transport of mining enterprises is a constant source of accidents. With increasing depth of mines and quarries and with an increase of the load on the transport systems, the problems of ensuring the safety and health of people, environmental protection. The solution of these problems is associated with the development of the theory of reliability of technical systems and the assessment of technogenic risks. Currently, in connection with the tightening of environmental requirements, a promising area is the use of tubular belt conveyors that cause the least damage to the environment compared with other types of conveyor transport. Due to the more complex processes occurring when tubular conveyors operate, risk factors and their consequences differ significantly from risk factors for other types of conveyor transport. Based on the experience of operation and from the preliminary analysis of the processes occurring during the operation of tubular conveyors, for them a classification of risk factors is external and internal factors, as well as risk factors affecting a person. The risk factors from external influences include temperature, humidity, dustiness of the atmosphere, soil instability, weather conditions, physical properties of load, geometry of the route. Internal risk factors are errors in designing, calculating the constructive and regime parameters of the conveyor, violation of the rules of operation and safety. Risk factors affecting a person when working a tubular conveyor are classified as mechanical, thermal, electrical and chemical. In addition, risk factors for a tubular conveyor are classified according to individual nodes of drive, stand, and belt. The risks of the failure of supports rollers of the tubular conveyor are considered. It is given a failure tree, where possible rollers failures are listed in detail and the risks of the torsion of the tubular belt leading to the conveyor failures.
Keywords: ribbon tubular conveyor, reliability, risk factors.
