Study on three-dimensional simulation and optimization system of mine ventilation network and its application in metal mines

The theory and functional characteristics of three-dimensional simulation and optimization system for mine ventilation network were introduced,and the required research contents about overall network of mine ventilation simulation were illustrated. Then combining a ventilation system instance in a large ferrous metal mine,against its problems such as total air volume is not enough,large-scale mechanized operations panel has poor environment, greater impact of natural air pressure,and imperfect ventilation structures,three technical solutions were designed to simulate and analysis the 3D simulation and optimization system of mine ventilation network,and the 3D simulation program optimization,air curtain selection,natural air pressure and other simulate principles and processes of mine ventilation system were shown. Finally the optimal technical solution of mine ventilation system was determined though simulation,the on-site measurement data was basically consistent with the simulated data. It can improve downhole ventilation effect,and ensure the safe and efficient mine production work.
