| The optimization of mine ventilation system is a decision question of a complicated system formed by numerous factors. The paper considers the technological and economic and safety factors synthetically, and analyses and sets up a new and overall and scientific optimization of mine ventilation system scheme index system corresponding to reality optimize, and utilizes two yuan contrast to fix right value of optimized index. Through the optimization of mine ventilation system scheme of HengYuan company, the paper finally realizes optimization of implementation system and guides the real work and obtaines the remarkable economic benefit and social benefit. |
