Research of Intelligent Control System with Automatic Forming and Constant Power Cutting of Tunneling Machine and Its Applicatio

Tunneling machine is the most important device in mechanical tunneling of coal mine roadway,but it is operated by driver with hands.Because of bad tunneling environment,poor working condition and dust and water fog influencing visual field of driver,bad forming quality of tunneling roadway section and big labor intensity are caused.Aiming at the above problems,the paper introduced an intelligent control system with automatic forming and constant power cutting of tunneling machine,introduced design and implementation of automatic forming control of tunneling roadway section and automatic traction speed-regulation control with constant power of cutting head of the system in details,and gave the application of the system on EBZ200 tunneling machine.The actual application showed that the system realizes functions of on-line remote monitoring,diagnosis and control,which makes operator away from working face and reduces person injury accidents,and has certain practical significance for automatic roadway tunneling with safety and high efficiency.
