The invention discloses a monitoring and early warning system and method for mine dangerous omen events, mainly including a server, a data transmission system, a contact wearable terminal, an electronic fence, a transmission equipment controller, a video collection terminal, and an environment monitoring terminal. The server is responsible for real-time storage and comprehensive analysis of the data collected by contact wearable terminals, electronic fences, transmission equipment controllers, and video acquisition terminals. When the monitoring data meets the pre-alarm setting conditions, an early-warning command is generated and sent to the designated wearer. , and provide specific early warning judgment methods. The present invention can automatically comprehensively monitor and warn personnel's physiological index information, walking trajectory, regional environmental parameters, and transmission equipment status, and can also automatically plan disaster avoidance routes and broadcast prompts when disasters are about to occur, thereby effectively reducing coal mine dangers accidents and improve self-rescue capabilities.
