A low cost, battery-operated, portable, real-time aerosol analyzer is not available for monitoring diesel particulate matter (DPM) concentrations in underground mines. This study summarizes a field evaluation conducted at an underground limestone mine to evaluate the potential of the TSI AM 510 portable photometer (equipped with a Dorr-Oliver cyclone and 1.0-mum impactor) to qualitatively track time-weighted average mass and elemental, organic, and total carbon (TC) measurements associated with diesel emissions. The calibration factor corrected correlation coefficient (R2) between the underground TC and photometer measurements was 0.93. The main issues holding back the use of a photometer for real-time estimation of DPM in an underground mine are the removal of non-DPM-associated particulate matter from the aerosol stream using devices, such as a cyclone and/or impactor and calibration of the photometer to mine-specific aerosol.
目前还没有一种低成本、电池供电、便携式的实时气溶胶分析仪可用于监测地下矿井中的柴油颗粒物（DPM）浓度。本研究总结了在一个地下石灰石矿进行的现场评估，以评估TSI AM 510便携式光度计（配备多尔-奥利弗旋风分离器和1.0微米冲击器）定性跟踪与柴油排放相关的时间加权平均质量以及元素碳、有机碳和总碳（TC）测量值的潜力。地下TC测量值与光度计测量值之间经校准因子校正后的相关系数（R2）为0.93。阻碍在地下矿井中使用光度计实时估算DPM的主要问题是使用旋风分离器和/或冲击器等设备从气溶胶流中去除与DPM无关的颗粒物，以及将光度计校准为特定于矿井的气溶胶。
