Optimizing Reformation of Ventilation Environment System in Beisu Coal Mine

For the practical problems of Beisu Coal Mine ventilation system, combined with measurement results of mine ventilation resistance, current situation of the ventilation system was analyzed. Then, Beisu Coal Mine ventilation system was optimized by continuous optimization method, the final optimization program was determined and main fan of the west and south wells were optimized and transformed. Combined with network calculation, the optimizing results and cost were analyzed.
