In the process of underground mining in coal mines,due to the interference of harsh environment and other factors,the electro-hydraulic control system of hydraulic support often fails.It is necessary to carry out maintenance and repair continuously and do a good job in fault diagnosis,so as to improve the stability of the electro-hydraulic control system.The composition and operation principle of the electro-hydraulic control system for hydraulic support were studied.Based on the fault factors of the electro-hydraulic control system,the rapid troubleshooting technology and the big data decision analysis service platform were analyzed in detail,and the actual operation effect of hydraulic supports was discussed.With the help of effective fault diagnosis,problems can be found and dealt with in time,in order to improve the stability of hydraulic supports.
