Abstract: The safety and reliability of underground ventilation system is the key link of mine safety production, and intelligent ventilation system can effectively reduce the occurrence of potential safety hazards.By analyzing the principle, objectives, key technologies and equipment of intelligent ventilation, aiming at the problems of unbalanced wind resistance and inability to realize on demand ventilation in the ventilation system of Piaotang Tungsten Mine, this paper adjusts the layout position of sensors, transforms fans with frequency conversion and built an intelligent ventilation management platform, and completes the pilot intelligent ventilation system test of 388 working face and 448 working face.The intelligent management of the pilot ventilation system is realized.The research results show that on the basis of meeting the underground on-demand ventilation, the intelligent ventilation system can greatly reduce the workload of manual data acquisition, save the ventilation cost, effectively ensure the safe production and operation environment of the mine, reduce the overall energy consumption of the mine, and provide support for the construction of intelligent mine.
