Abstract: To further deepen the pivotal role of digital mining in intelligent unmanned mining and intelligent mine construction,and to form a stable,reliable and practical guiding overall framework,a design and operation mode of production system for fully mechanized mining face based on digital twin theory was proposed.Driven by the design and monitoring service system of fully mechanized coal mining production system,the iteration operation of production factors' management configuration and the pre-simulation of production process and real-time monitoring in the physical fully mechanized mining face,the virtual fully mechanized mining face and the design and the monitoring service system was researched.Integration and fusion of all elements,data and processes were realized,and the optimal configuration of production system together with coordinated safe and efficient mining of equipment was achieved.The technical framework and key technologies of the three stages were described in detail.By taking a prototype system as an example,the digital design of fully mechanized mining equipment and coal seam,the virtual simulation mining simulation and the virtual monitoring and control driven by real-time operation data could be completed in sequence.The proposed model provided the core key technologies and platform for intelligent unmanned mining.
