In view of the important demand of information and intelligent upgrading of metal mine ventilation in China, the principle, key technology and system composition of mine intelligent ventilation are systematically studied. It is clearly stated that intelligent mine ventilation is a kind of operation which can supply air according to demand, it can transmit fresh air stably and economically to the mine continuously for personnel to breathe, dilute and discharge harmful gases and dust, improve the climatic conditions of the mine and have certain intelligent control of air flow during disaster relief. According to the existing problems of mine ventilation, this paper gives the ways to realize ventilation from the perspective of technical types, and expounds the safety strategy of metal mine ventilation. According to the concept of “combining peacetime and wartime”, it realizes the air supply according to demand and the intelligent decision-making and emergency control under the condition of abnormal disaster, which can not only meet the automatic management and maintenance of daily ventilation, but also can realize the emergency wind control in the period of disaster and effectively restrain the evolution of disaster. The theory and technology discussed in this paper can provide reference for building intelligent ventilation system in metal mines.
