双阳煤矿中央采区通风系统改造

Reform of Ventilation System in Central Mining Area in Shuangyang Coal Mine

随着矿井规模产量的增加,采面块段小,采煤速度快,必须增加掘进队组,保持采掘平衡。只有合理改造矿井通风系统,降阻、增风,才能保证安全生产提高经济效益。

With the increase in mine - scale production, small- block face, fast mining speed, the driving team group must be increased to maintain the balance between mining and driving. Reasonable transformation of the mine ventilation system, lowering resistance, increasing the wind, can ensure safety in production and increase economic efficiency.
