Abstract: Mine dust is a typical associated pollutant produced in the process of mining，transporta⁃ tion and storage in mines. It is not only easy to cause occupational diseases such as pneumoconiosis，re⁃ duce operational visibility，but also has the risk of flammable dust explosion，which seriously restricts the safe production and ecological green development of mines. In order to systematically sort out the develop⁃ ment status of mine chemical dust suppression technology，clarify the technical advantages and disadvantag⁃ es of various dust suppression materials，and point out the direction of industrial innovation and develop⁃ ment，the technical system of conventional dust prevention and control in mines is systematically summa⁃ rized. The mechanism and research progress of three types of traditional chemical dust suppressants (wet⁃ ting type，bonding type and condensing type) and two types of new dust suppressants (composite type and in⁃ telligent green type) are classified and elaborated. The core innovation mechanisms such as surfactant com⁃ pounding and coordination，polymer crosslinking and consolidation，and microbial enzyme catalytic regula⁃ tion are emphatically analyzed. The dust suppression advantages and application potential of new materials such as nano-modification，intelligent response and ecological substrate are summarized. By comparing the performance differences and technical shortcomings of traditional and new dust suppressants，the innovative concept of targeted dust suppression suitable for complex mine conditions is proposed. From the perspective of interdisciplinary integration，the future technology development path of intelligent molecular design，arti⁃ ficial intelligence high-throughput screening and solid waste recycling is prospected. The research results can provide scientific reference and technical reference for the precise prevention and control of mine dust， the development and engineering application of green and efficient chemical dust suppressants.
