摘要：This article shows that a significant part of the cost of coal is the cost of transporting it from the long wall to the mine surface, which makes it important to search for reserves in order to increase the efficiency of using mine vehicles, in particular, belt conveyors. This article proposes a method for diagnosing the state of gears of mine belt conveyors based on the actual condition of the lubricating oil. The advantages of combining the study of oil parameters by spectroscopic and microscopic methods are shown. The results of testing lubricating oil of the mine gearboxes located on belt conveyors installed in a single transport and process chain. In order to determine the concentration of wear products the oil was examined with an optical emission spectrometer. For lubricating oil, in which excess wear was observed, a microscopic examination was carried out to clarify the types of wear. Micrographs of wear particles in lubricating oil are given. It characterizes one or another type of wear or their combination. This particular combination of methods increases the probability of identifying possible malfunctions of gearboxes at an early stage of defect development. Thus, the introduction of this technique will reduce the duration of unplanned emergency downtime of belt conveyors and improve the safety of mine transport.
