Study On Ventilation System Optimization Of Yunnan Pulang Copper Mine

The nature of the mine ventilation is organizing the air flow in the mine effectively,reasonably and feasibly,meanwhile dilute and exhaust harmful substance to create a good working environment underground. So mine ventilation system can satisfy the production requirements of the safety and normal in the mine that it is the important for the mine.According to geography geological conditions,haulage,mining methods of the original data on the PuLang copper mine in this article, and on the basis of a large number of references, combining with the characteristics of the mine ventilation system of the mine,and on the basis of the meeting mine ventilation system,establishing a multi-fan multistage ventilation system and pressure pumping hybrid ventilation,then calculating the required amount of wind.According to the above conclusion,this article puts forward more than reasonable and feasible ventilation scheme,then paints a plurality of ventilation netwprk graph on the 3D Vent ventilation solution software,installing the fan and selecting the fan in the fan management library of the each ventilation network graph,final inspection network and the output of each solver results of different ventilation programs report in this article.By consulting a large number of references about the ventilation evaluation in this article,and analyzing of the characteristics of the mine,it establishes a more scientific and comprehensive evaluation system ventilation system,using the analytic hierarchy process and average variance to get all index weights complexly,then using scoring method to get the optimal ventilation scheme.By combining the much the original material of the ventilation system in the PuLang copper mine with a large number of references, putting forward a number of reasonable and feasible ventilation scheme, and selecting the optimal ventilation scheme in a given plurality of ventilation scheme,ensuring the work of Mine Ventilation System Optimization successfully,working for the safety production of the mine has made a guiding role.It promotes some economic development later, meanwhile it is possible to provide the appropriate reference to similar mine ventilation optimization.
