Countermeasures on Stable Economic Operation of Ventilation System in Senescence Mine
Abstract：According to the old and aging ventilation equipment, complicated mine ventilation network system, frequent changing of the operation locations, long ventilation distance, many ventilation facilities, high ventilation resistance, ventilation difficulty and other prob- lems existed in the senescence mine ventilation system of Jingxing No. 3 Mine, based on the design of the mine ventilation system applied, the mine ventilation network was scientifically and rationally optimized. When the measures of the ventilation network resistance reduced, ventilation lost reduced, reconstruction of the irrational and uneconomic ventilation equipment and elimination of the backward and low ef- ficient main ventilators, the adjustment of mine performance, the frequency converted technology, the controllable circulated ventilation and other technology were applied to ensure the high efficient and economic operation of the ventilation system in senescence mine.
