Abstract: Mine ventilation is the cornerstone of safe production in the mine.The development of intelligent ventilation technology and equipment under the intelligent background is the only way to ensure the development of less humanized and unmanned coal mines in China.This paper systematically summarizes the recent research and practice results of mine ventilation technology and equipment in China from the aspects of ventilation parameter measurement and monitoring，ventilation network analysis and decision-making，ventilation control technology and equipment.The four problemsare that the accuracy of ventilation parameter measurement and monitoring is low and it is difficult to meet the needs of accurate decision-making； the lack of effective decision-making model for air volume regulation，the development of regulatory equipment is lagging behind，and it is difficult to achieve dynamic quantitative adjustment； immature development of ventilation hidden dangers and disaster identification technology，and lack of effective means of prevention and early warning and emergency control.In response to these technical problems，three key research and development directions to realize the intelligentization of mine ventilation are proposed:intelligent perception，intelligent decision-making，and intelligent control.The key core technical content that each research and development direction should focus on is given，that is，automatic mapping through the research and development ventilation system to quickly and accurately obtain technology and ventilation parameters to realize intelligent sensing of basic ventilation data； To realize intelligent decision-making of ventilation technology through research and development data-driven network model construction methods，ventilation network and ventilation regulation linkage analysis and decision-making technology，ventilation hidden danger automatic identification and alarm technology； Intelligent control of ventilation disasters is realized through the development of accurate methods for identifying disasters in ventilation and disaster control equipment.Relying on the above technical equipment，a set of intelligent ventilation technology equipment system is formed to realize unmanned and intelligent mine ventilation.
