Abstract: For the problems of traditional labor strength, complex welding process, low efficiency, higher labor cost, the coal mine hydraulic support automatic welding operation system, various information technology integration and fusion, put forward a kind of hydraulic support automatic welding operation system, analyze the hydraulic support welding process, establish software control system architecture and based on B / S architecture mechanism, through the data acquisition and analysis system, to ensure the welding sequence and welding quality of hydraulic support. After the field application, it shows that the automatic welding operation system of coal mine hydraulic support can monitor the welding process online and control the production rhythm, which greatly improves the production efficiency, reduces the labor intensity of workers, reduces the labor of about 3-5 people every year, achieves satisfactory application effect.
