Abstract: Aiming at personnel behavior control at key operation sites in coal mines and aiming at improving safety, the architecture of AI video intelligent identification system is established. The selection and analysis of internal components of the identification system are carried out. Intelligent identification technology is used to automatically identify and analyze video content. The image, sound and other elements in the video are processed and analyzed at a deep level to extract valuable information. The system has the function of standardized operation supervision of personnel in different dangerous areas, and has been implemented in different scenarios such as mining face, transportation system and hoisting system, with stable performance and good warning effect, which can effectively ensure safe production and improve labor productivity and management levell.
