摘　　要：对龙山煤矿通风设计、矿井风量、风压及等积孔的计算得出:龙山煤矿生产初期等积孔为2.78m2,负压为493.88Pa,属于容易通风矿井;矿井生产后期等积孔为1.67m2,负压为1375.7Pa,属于中等通风矿井。表明龙山矿井不论是建井初期还是后期井下通风系统良好,通风系统设计合理。结果表明龙山煤矿井为小阻力通风矿井,属于容易通风型矿井。Calculating the air quantity,air pressure and equivalent orifice of Longshan Coal mine,the result shows Longshan Coal Mine production early orifice is 2. 78m2,negative pressure is 493. 88 Pa,which belongs to the easy ventilation mine; mine production tail orifice is 1. 67m2,negative pressure is 1375. 7Pa,which belongs to the middle ventilation mine,whether the early or late of mine,the mine ventilation system is well,the design of the ventilation system is reasonable. The results show that the Longshan Mine Ventilation resistance is small,mine belongs to the easy ventilation mine.
