The Research Of Optimization And Alternation To Tie Xin Mine's Ventilation System

Ventilation system is an important component of the mine production system, the reasonable mine ventilation system could ensure production safety. It is composed by the power and ventilation devices, mine ventilation network, monitoring and control facilities.By a complete and detail investigation about the mineral ventilation system, we practically measured the mineral ventilation systematical resistance, and mastered the distribution of ventilation resistance, acquired frictional air resistant coefficient of the main lane under mineral well. Through the resistance distribution and Path resistance of the "three zone" of the new coal mine, the power distribution is analyzed:North Wing of the return air lane,+586 driftway, return air shaft of mine ventilation resistance centered position, especially the return air shaft curb mine ventilation?Three different reconstruction schemes that is to meet the problems of mine ventilation system, combined with the measured data by using the computer to the three different schemes were simulated, based on the simulation results of three schemes are comPared and analyzed, finally selected ventilation system transformation scheme. The proposed plans were applied to the scene and obtain good effect, proved the ventilation system reform adjustment scheme is feasible and effective.
