Abstract:
Aiming at the situations of lacking of wind volume in later period and the excavation connection unbalanced by using 2 × 30 kW partial ventilator during the mining process of 3 000 m long distance single roadway of Yanbei coal mine,this paper selects the super power 4 × 37 kW FBDY ventilator to do the experimental study,which indicates that this ventilator can realize effectively long distance,super power wind volume transportation of heading face,and decrease the roadway temperature by more 2 ℃ than 2 × 30 kW counter-rotary partial ventilator,and the effective wind volume increases by 57.91%.
