通风所消耗的电能在矿井生产总能耗中占较大的比例,一般约占20%,高者可达30%以上。改善通风管理,减少电耗是节约电能的有效措施。本文是从分析通风系统各参数与能耗的关系,寻求在保证安全生产的前提下,节约电能的措施。衡量通风耗能的指标是吨煤耗电量 e。对于单风井矿井e=(?)×24/A_d KW·h/t即:e=(?)(1)式中 Q_f——扇风机风量,m~3/s;H_f——扇风机风压,P(?);η——总效率,η=η×η_e×η(?)×η_t×ηL;η_f——扇风机运转效率;η_e——扇风机电机效率;
Ventilation consumes a lot of electricity in the total energy consumption of mine production accounted for a large proportion, usually about 20%, the higher up to 30%. Improving ventilation management and reducing power consumption are effective measures to save electricity. This article is from the analysis of ventilation system parameters and the relationship between energy consumption, seeking to ensure safe production under the premise of saving energy measures. The measure of ventilation energy consumption is tons of coal consumption e. For a single shaft mine e = (?) × 24 / A_d KW · h / t that is: e = (?) (1) Where Q_f - fan fan air flow, m ~ 3 / s; Η, η = η × η_e × η (?) × η_t × ηL; η_f - fan fan operating efficiency; η_e - fan fan motor efficiency;
