Visualization Analysis of Digital Twins in Domestic Intelligent Mine Field Based on CiteSpace
To systematically analyze the characteristics of the research and application of digital twin technology in the field of mining,the literature data are retrieved based on the keywords related to intelligent mine digital twin in the database of CNKI,the knowledge map is constructed by using visualized bibliometric analysis Citespace software,then the features,research hotspots and frontier trends of the collected literature are analyzed.Results show that since 2016,the number of publications on intelligent mine digital twin research has increased rapidly,and a core team has been initially formed,with sparse cooperations among teams.China University of Mining and Technology(Beijing)and Xi'an University of Science and Technology are the major publishing insti-tutions,followed by China Coal Science and Technology Group and coal enterprises.Research hotspots are dis-tributed in six aspects:open-pit coal mine,coal mine,artificial intelligence,digital twinning,virtual simulation and simulation.Such frontier technologies have phased features,and various technological hotspots are evolved well.Artificial intelligence,digital twin and virtual simulation integrate together to promote the development of in-telligent mine.
