Abstract: In order to solve the problems of the more dust in working process and the operator can’t see clearly the(cutting) header’s physical location to cause less dig and over dig,the paper designed a visuali-(zation) monitoring system of cutting process of boom miner based on C7-636,introduced system compo-(sition) and implementation of visualization monitoring interface of cutting process in details,and gave(design) of system software.Displayed curve and data of the system could provide real-time information for operator,which could reduce the phenomenon of less dig and over dig in the process of digging tunnel and improve construction quality of the tunnel.
