Abstract: In order to further improve the application efficiency of spray dust removal technology in mine dust control，aiming at the problems existing in the traditional single spray dust removal technology in the current mine operating environment，the atomization and dust capture mechanism analysis and applica⁃ tion evaluation of spray dust removal technology were systematically carried out. The atomization mechanism and dust removal characteristics of different spray dust removal technologies were discussed. The applicable conditions of pressure atomization，pneumatic atomization and ultrasonic atomization and the mechanism of their interaction with dust particles were systematically analyzed. The synergistic mechanism of synergistic spray dust removal technology is analyzed in depth，and the technical challenges that synergistic spray dust removal technology will face in practical application are proposed. The future development trend of mine spray dust removal technology is to move towards a more efficient，environmentally friendly and economical direction. The in-depth research and application of multi-technology synergy systems will become an impor⁃ tant development direction. At the same time，focusing on breaking through the core technology of atomiza⁃ tion and optimizing the energy saving and environmental protection performance of the system，the simulta⁃ neous improvement of dust removal efficiency and sustainability is realized，which will provide an important
