Abstract：Aiming at the problems of delayed data transmission,lack of action prediction and fault a-larm in the monitoring system of the boring working face of raise boring machine,a digital twin real-time monitoring system for the large-diameter reamer of raise boring machine was designed.The sys-tem consisted of aerial modules,cloud space modules,physical entities,virtual space modules and digital twins,forming a set of intelligent monitoring systems for fine positioning and intelligent moni-toring of the working face of large-diameter raise boring machine for air-cloud-ground-shaft intelligent monitoring.In the uneven interaction between soft and hard strata,the range of boring parameters changes was large,and the construction parameters changed quickly.By using of sensing equipment and multi-source data fusion,a virtual real interaction intelligent monitoring system was established based on a unified coordinate system,and a simulation approximate prediction model was proposed to improve the real-time,accuracy,and completeness of the monitoring system for the large-diameter reamer of the raise boring machine.
