Abstract The dust problem caused by the improvement of mine mechanization and intelligence level is becoming more and more serious. It is of great significance to explore the law of airflow-dust migration and master the movement characteristics of airflow and dust in the working face to improve the dust control measures in the working face, improve the underground working environment and accelerate the realization of the goal of green mine. By consulting domestic and foreign literature, investigating relevant research progress and practical experience, the current wind flow field and its influence on dust distribution are studied from the aspects of dust force movement principle, similar experiment design, numerical simulation research, combined method effect evaluation and so on. It is considered that there are some problems such as complex interaction between wind flow field and dust, incomplete research on dust force movement mechanism and motion path, and unclear relationship between different factor combination and dust migration law. From the perspective of improving the law to practicality and universality, it is proposed that the research focus of airflow-dust transport law should be on eight aspects : clarifying the mechanism of dust transport force and the synergy mechanism of force, establishing multi-parameter characterization of transport law, improving the precision of monitoring instruments, weakening the influence of secondary factors on similar experimental results, enhancing the understanding of the mechanical characteristics of airflow field and dust transport, clarifying the coupling relationship between influencing factors,constructing a mathematical model suitable for gas-solid two-phase flow and improving the particle motion diffusion equation.

Key words： characteristics of wind flow movement dust migration law dust control measures factor coupling relationship
