【正文】 of working face, the coal face and the heading face ventilation mode for Anshan mine actual condition, and calculates the coal face and the tunneling working surface for air quantity and air volume, the entire mine. The analysis of mine ventilation resistance calculation easy and difficult period, bined with the advantages and disadvantages of the main fan at present, selection of main fan andesitic coal mine, and mine ventilation system graph and ventilation work chart drawing. Finally, according to the actual conditions of Anshan mine, put forward the related safety management measures one through three. Design of ventilation system in this thesis can lay a foundation for the safe production of the mine. Keywords: ventilation system, ventilation system, ventilation design, measures Type of thesis: Design 目錄 1 緒論
