Aiming at the local ventilation intelligent construction demand of 12307 heading face of Wangjialing Mine, a local intelligent ventilation management and control system for coal mines is proposed, and the system composition, function realization and key technology are studied in detail. Through multi-sensor real-time monitoring of environmental atmosphere data, the system intelligently regulates local ventilation fan operation parameters, adjusts air supply and controls gas concentration in the return flow to achieve safe emissions. The mine industrial Ethernet networking function enables data interchange of various parameters. The completed intelligent ventilation management and control system can achieve remote control, automation, and intelligence as well as communication functions, laying the foundation for intelligent air volume regulation and risk prediction of local ventilation at the heading face and guaranteeing safe and efficient digging at the workface.
