摘　　要：本文以矿井通风网络入风段和用风段氡析出规律为出发点,由铀矿通风降氡基本方程导出不同通风方式下铀矿降氡需风量的计算公式,并由入风段有效供风能力导出优势通风方式评价指标,给出铀矿通风降氡方式的判别方法。Based on the radon exudation rule in the inlet and the using sections of the mine ventilation network,the calculation formula of air demand for radon reduction in uranium mines under different ventilation modes is derived from the basic equation of radon reduction ventilation in uranium mines.The evaluation indicators of dominant ventilation mode are derived from the effective air supply capacity of the inlet section.And the discrimination method of radon reduction ventilation mode in uranium mines is suggested.
