Investigation on the Reconstruction and Extension of Mine Ventilation System and its Optimization

Based on investigation,measuring and analyses on the renovation and expansion for the domestic mine ventilation system and by applying the basic indicators,integrated indicators and supplementary indicators identified by the mine ventilation system,it is found out the common ventilation problems existed in the renovation and expansion of the mine ventilation system and the main reasons affecting the renovation and expansion of the mine ventilation are summarized and analyzed.For the main ventilation problems,the paper puts forward some optimization methods of ventilation equipment,ventilation network and airflow regulation facility and the management measures of mine ventilation on the renovation and expansion of the mine ventilation system.It has achieved good results and proved worthwhile to be popularized.
