Abstract: The realization of intelligent mine ventilation is the main technical means to build intelligent mines. Aiming at the problems of inaccurate adjustment of the ventilation system, low level of intelligence, and early warning information to be reflected in the emergency and disaster relief command center, a construction scheme of mine intelligent ventilation system was proposed. The scheme consists of underground monitoring equipment and a ground control center. It aims to establish a 3D ventilation simulation and intelligent identification platform for hidden dangers, and realize real-time dynamic analysis of mine ventilation data, 3D visualization, and safety early warning and auxiliary decision-making. Five key technologies of ventilation monitoring database, 3D ventilation simulation, AI video intelligent recognition, early warning and auxiliary decision-making, and system linkage control were studied in detail, and their technical characteristics and implementation plans were elaborated. Based on computer software development technology, 3D simulation technology and artificial intelligence technology, the mine intelligent ventilation system is designed and developed.
