| 摘 要： | 着重研究了废旧巷道对含尘气流的自净特性,进而对利用旧巷自净进行受控循环通风的设想进行探讨;在对浓度场和流体场测试的基础上,建立了粒子在废旧巷道沉降的紊流弥散模型,对边界条件进行了正确的假设,得出了稳态时的自净效率公式;导出了风量与巷道体积的关系表达式。

| Abstract: | The article researches specially self - purification of dust - contained air flow in deposed and old laneway,and then discusses the thought of appling self - purification for controld circle ventilation;Builds turbulent dispersion model of dust sedimentation in deposed and old laneway on the basis of test of concentration field and flow field,correctly supposes limit conditions,and gets self - purification efficiency equation, at last, deduces the relation expression between wind volume and volume of laneway. |

| Keywords: | Turbulent dispersion Air - flow uneven Secondary fly - up |
