In order to solve the current problems of lack of visual human-machine interaction control,lack of digital twin dynamic modeling of the heading face,and lack of fusion between the roadway model and the positioning and navigation system of the tunneling machine,a method of automatic cutting for coal mine tunneling machine based on the three-dimensional digital twin technology was put forward,generating a cutting template by using the roadway model of the three-dimensional digital twin technology,realizing the automatic cutting of the pre-set cutting section of the tunneling machine,avoiding the safety risks faced by the personnel on-site control,and achieving the purpose of manual,remote and visualized control of the safe and automatic operation of the tunneling machine.The construction method and data-driven logic of digital roadways and tunneling machine models were introduced,and the automatic cutting control method of tunneling machines was expounded in detail.The results has shown that this method avoids the influence of dust on the automatic cutting of tunneling machine,reduces the risk of on-site operation and labor intensity of personnel,and solves the problems of low accuracy of remote cutting of tunneling machine and poor quality of roadway section forming.
