The use of 3D simulation system in mine ventilation management

The Donghai mine has been mined to -1000 meters, three mining areas share one return shaft, some laneway resistance values are very large, and fan air pressure reach more than 3500pa. The ventilation system is complex and difficult to manage. To solve this problem, the practical use of three-dimensional simulation software Ventsim in the Donghai mine is described in detail. Real-time air network calculation, dynamic show the direction of airflow, air quantity, velocity and other parameters are the basic use of ventsim, which can be scientific, accurate and fast simulating the ventilation status, reduction in resistance and contaminant spread. The system satisfy the requirements of Donghai mine ventilation management and provide a scientific and reliable data for decision-makers, which has improve the level of Donghai mine ventilation management.
