The Research Of Optimization And Alternation To Wang Ping Coal Mine’s Ventilation System

Ventilation system is an important component of the mine produetion system,the reasonablemine ventilation system could ensure produetion safety.It is composed by the power andventilation deviees，mine ventilation network，monitoring and control faeilities.By a complete and detail investigation about the mineral vetilation system,wepractically measured the mineral ventilation systermatical resistance,and mastered thedistuibution of vetilation resistance,acquired frictional air resistant coefficient of the themain lane under mineral well,provided the basis of mine ventilation system optimizationand transformation.Then using computer determination for data analysis to therationality of ventilation network structure and resistance distribution,the simulationdraws up ventilates the plan and makes the optimization to ventilate the plan.Theproposed plans were applied to the scene and obtain good effect,proved the ventilationsystem reform and network optimization adjustment scheme is feasible and effective.
