Abstract: In order to solve the ventilation problems, such as uneven air volume and increased resistance with the increase of mining depth and range in a mine, and ensure the safe production of the mine, this study takes the ventilation system of the mine as the object, and uses Ventsim three-dimensional ventilation simulation software to carry out optimization research. Firstly, through on-site investigation and measurement, the mine ventilation parameters are obtained, and the current situation of the air volume of the hybrid ventilation mode is clarified, as well as the problems such as air volume deviation, resistance overrun and abnormal wind speed. Then, based on the ventilation network theory, a three-dimensional ventilation model of the mine is constructed, reasonable simulation parameters are set and the current situation is simulated and verified. The research provides a scientific basis for the subsequent optimization scheme and screening of the optimal strategy, and has important engineering value for improving the efficiency of mine ventilation system, reducing safety risks and promoting sustainable development.
