低成本、电池供电、便携式、实时气溶胶分析仪无法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 Dorr-Oliver 旋风分离器和 1.0 µm 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、有机和总碳 (TC) 测量的潜力。地下 TC 和光度计测量值之间的校准因子校正相关系数 (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，以及根据矿山特定气溶胶对光度计进行校准。
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-μm 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.
