Abstract: With the help of VOSviewer software,the author co-citation,keyword co-citation and other digital characteristics of 1 044 literatures collected in CNKI database from 2000 to 2022 were displayed in the form of knowledge graph. The time distribution of the development in the field of mine dust control was analyzed by bibliometrics method. The study trends and progress of mine dust control are discussed. The study results show that the research on mine dust control from 2000 to 2022 presents an overall upward trend,which can be divided into three stages according to the number of annual publications and the relative number of annual publications,namely,the germination period ( from 2000 to 2005),the rapid development period(from 2006 to 2015) and the take-off period ( since 2016). In addition,the co-citation analysis of 1 831 authors shows that five closely related academic groups have been formed. The co-occurrence analysis of 3 471 keywords shows that there have been five highly correlated keyword clusters,namely,coal mine dust control cluster,dust hazard cluster,dust control cluster, dust concentration cluster and numerical simulation cluster. On the basis of the above analysis,the paper further analyzes the shortcomings of mine dust control research in China at the present stage,namely. ① The conversion rate of dust control theoretical research results needs to be improved;② The precision monitoring technology and system of mine dust need to be further upgraded;③ Under the background of intelligent mine construction,the research and development and application of mine dust intelligent dust removal system need to be further deepened;④ Under the background of green mine construction,social environmental protection requirements are constantly strengthened,which leads to the certain restriction of the application of many traditional and effective dust suppression methods. It is believed that the key development direction of this field in the future can be summarized as:① Deepen the theoretical research on mine dust control,give full play to the advantages of interdisciplinary research,carry out joint research between schools and enterprises,increase the practical application of theories,strengthen the dialogue and combination of theory and practice,and further improve the conversion rate of scientific and technological achievements;② Strengthen the research and development of real-time monitoring and continuous monitoring systems and equipment for mine dust based on accurate dust monitoring and employee health;③ Deepen the construction of precise intelligent dust removal system,improve the accuracy of real-time monitoring of mine dust,and strengthen the depth and breadth of information application;④ Through technological breakthroughs to break the difficult coexistence of environmental protection and economy,reduce the cost of environmental protection,and improve environmental benefits.
