The Red Hill Copper Mine Ventilation System To Optimize The Transformation Of Research

Mine ventilation system optimization is a decision-making problem about complexity system which is composed of many integrating, interrelating and interdependent quantitative and qualitative factors. On the base of synthetically considering all-round factor such as technology, economy and safety, the paper analyzes and establishes a set of new index system about optimization scheme of mine ventilation which are more comprehensive, scientific and practical. Moreover, the paper determines weights of all optimization indexes by means of AHP method.In order to get the essential basic information for ventilation system optimization , the paper investigates and measures the current condition of ventilation system of Dahongshan Copper Mine and draws ventilation networks diagram and ventilation system diagram of dahongshan. On the basis of those, for its developing layout and problems that need to be solved in the new and far future, and according to the features of their own corresponding ventilation systems, many doable design schemes are respectively drawn out at first. Then based on the established optimization index system, these schemes areoptimized by using a new Grey System Theory---GreyRelational Analysis method, and an optimal scheme of ventilation system is selected finally.The optimization of system is achieved finally through the scheme optimization selection of ventilation system of Dahongshan Copper Mine, which directs practical work, and the remarkable social and economic benefits are gained. Besides, another scientific means and theoretic basis are provided for the optimization selection of schemes of mine ventilation system.
