十三、怎样计算铀矿井通风所需风量? 铀矿山通风所需风量,主要按排除氡及其子体计算。按排氡计算,即根据矿井氡析出量和回风流中最高允许浓度计算。按排氡子体计算,即根据矿井中氡子体浓度、通风体积和完全换气时计算。这两种计算方法如下: 1.按排氡气计算所需风量根据稀释和排除矿井氡计算所需风量,设计中一般只考虑氡的主要来源(即从矿体
Thirteen, how to calculate the amount of air required for ventilation of uranium mines? Ventilation required for ventilation of uranium mines, mainly calculated by excluding radon and its daughters. According to row radon calculation, that is based on the amount of radon in the mine and return air flow in the maximum allowable concentration calculation. According to the calculation of radon progeny, that is calculated according to the concentrations of radon progeny in the mine, ventilation volume and complete ventilation. The two methods of calculation are as follows: 1. Calculating the required air volume based on radon. Calculating the required air volume based on the radon dilution and exclusion, the main sources of radon are generally considered in the design (ie,
