Abstract: Improving the operational reliability of mining equipment, and as a result, the efficiency and growth of production, continues to be an urgent task for enterprises of the fuel and energy complex. The high technical level of mining machinery products is capable of ensuring trouble-free and energy-efficient operation of mines, mines and processing plants. Lubricants are one of the components that determine the technical condition of mining machines. A brief analysis of the history of additives in lubricating oils is given. Basic information about the purpose and functions of additives is given. A brief analysis of the history of the development of methods for assessing oil condition by various parameters is considered. Input control of the lubricating oil parameters allows you to evaluate the quality of the oil and the possibility of its use for a specific type of equipment or even a specific machine. It is shown that during operation, the rate of oil degradation, the loss of dispersant, foam and detergent additives, as well as the accumulation of mechanical impurities, under the same design conditions, is different. Systematic sampling and determination of basic parameters such as viscosity, flash point, iron, silicon, copper and some other components make it possible not only to determine the rational timing of oil change. By making possible adjustments to some parameters, it is also possible to extend the service life of gearboxes under specific operating conditions. The article provides a justification for the operational analysis of lubricating oil in belt conveyor gearboxes. The results of a study of oil parameters starting from commissioning and after twenty-six months of operation in underground mining conditions are presented. These studies make it possible to implement proactive maintenance of belt conveyor drives and thereby achieve an economic effect during their operation. The directions of further development of the sciences of friction and lubricants are considered.
