Research on electro-hydraulic control system for hydraulic support at coal mine
Based on the investigation and analysis of the situation in full mechanized coal mining face at home and abroad, the electro-hydraulic control system for hydraulic support is put forward, designed and realized. It adopted intrinsically safe circuit design technology and field bus technology to connect all control units to the host computer. Each control unit of the control system is equipped with one hydraulic support. Certain control unit(s) controlled by either the other control units or the host computer can operate adjacent support, distant support or a group of supports. Host computer in an explosion-proof housing also has the functions of real-time monitoring, remote control, fault diagnosis and upload data etc. The result of industrial experiment up to three months shows that the system works reliably and meets the design requirements.
