铀矿井主要通风井巷经济断面优化

The optimal economical section of the main ventilation shaft of a uranium mine

矿井通风费用主要由基建井巷设备投资、维修费和通风动力费构成。通过通风费用计算公式,探求主要通风井巷的最优经济断面,以降低基建投资和通风运营成本,使矿井通风总费用最低。推导的最优经济断面计算公式便于设计人员对主要通风井巷经济断面进行计算和校核。

The costs of mine ventilation in uranium mines contain equipment cost for shaft sinking and drifting infrastructure, maintenance cost,and power cost. The optimal economical section of a ventilation shaft was explored by formula of ventilation cost in order to reduce the investment in infrastructure and operating cost in ventilation, and make the total ventilation expense in the shaft lowest. A formula of calculating the optimal economical section of the ventilation shaft sinking and drifting was derived, and the formula is convenient for designers to calculate and check the main economical section of the ventilation shaft sinking and drifting.
