Diagnostics of underground mining machinery

The paper presents a system for machinery diagnostics, developed by KOMAG Institute of Mining Technology. This system consists of a software part, installed on a PC, and a hardware part, integrated with the diagnosed machine. The idea of the system is the early damage detection of gears components and the identification of the damage location with the prediction of its development, which allows to increase the operating capability of the machine. The system is dedicated to work with the machines operating in harsh environmental conditions, which exist in the mines. Its characteristic feature is the ability to operate automatically, at varying load conditions. Information about the condition of the machine is determined by a continuous diagnosis, carried out on the basis of a set of signals from vibration sensors, pulse sensors and from the internal machine control system.
