The three-dimensional ventilation digital twin system in Hongkun mining area was estab⁃lished by using accurate measurement technology of ventilation parameters,three-dimensional modeling technology,GinVent three-dimensional ventilation digital twin technology and big data analysis technology.Through the established digital twin system and multi-dimensional variables,the quantitative analysis of the current situation of the ventilation system,the analysis of the transformation scheme,the analysis of the exhaust gas diffusion path of the diesel vehicle,and the quantitative analysis of the parameter optimization of the newly excavated return air shaft scheme are carried out.Combined with the actual production situation of the mining area,a variety of feasible optimization schemes are proposed.The optimization scheme realizes the doubling of the effective air volume in the deep area below+110 m in the mining area,and the discharge time of the deep dirty air in the working face is greatly shortened.The research has formed a set of new metal mine ventilation management mode based on the accurate three-dimensional modeling of the total elements of the metal mine ventilation system,the quantitative numerical simulation analysis of the ventilation sys⁃tem,and the construction of the three-dimensional ventilation digital twin system.It provides technical re⁃serves for deep mining,underground environmental governance and mine intelligent construction in Hong⁃kun mining area.
