Research and application of intelligent ventilation technology in Hanjiawan Coal Mine

Taking Hanjiawan Coal Mine as the research object, an intelligent ventilation decision-making management and control platform based on dynamic perception of basic parameters, intelligent management and control of ventilation equipment, accurate identification of regional air-reversing and belt fires, fire classification early warning and management was built to realize the four key technologies, namely unmanned wind measurement, automatic air regulation, intelligent regional air-reversing and advanced fire prevention and control, the technical system and system construction of intelligent ventilation technology are mainly introduced. The field application of this technology shows that the remote automatic unmanned wind measurement, remote automatic control of regional air volume and remote control of regional air-reversing are realized, which significantly improves the automation and intelligence level of the ventilation system in Hanjiawan Coal Mine.
