Abstract: Coal mining has an important impact on economic development and people's lives. In order to ensure the smooth progress of mining, in addition to the use of leading coal mining technology, leading coal mine electromechanical facilities should also be used.For coal mine electromechanical facilities used in coal mining work, the operating pressure is high. Under the influence of the operating environment and mining difficulty,the failure rate of coal mine electromechanical equipment operation is relatively high. At this time,the fault detection and diagnosis technology needs to be used flexibly to ensure Based on the stable operation of coal mine electromechanical equipment, this article conducts an in-depth study on the application of mechanical equipment fault diagnosis and measurement technology in the quality control of coal mine electromechanical equipment, in order to promote the rapid development of the coal mining industry.
