Study on the Optimization of Ventilation System of Metal Mine

This paper expounds the content of investigation on mine ventilation system.The problems existing in mine ventilation system can be found by investigation,test and analysis.In light of the problems existing in the ventilation system of a mine,such as the relatively low running efficiency of the main fan,insufficient total air input of mine,incomplete ventilation structure,etc.,two technological reformation schemes for the optimization of the ventilation system were prepared.And 3-Dimensional Simulation and network calculation of the reformation schemes were made by using network analysis software of mine ventilation system.By comparing the results of the network calculation as well as technical and economic analysis,the optimal technological reformation scheme for the mine ventilation system was determined.
