This study compares the ambient air particulate matter (PM10) data of 15 different coal mine environments. For most of these mine environments, the monitoring was carried out by different researchers using respirable dust sampler (RDS) that separates PM10 by centrifugal inertial separation. At two sites--Padmapur and Ghugus (Chandrapur, Maharashtra, India)--mass inertial impaction-based sampler was used for PM10 monitoring. It is observed that the spatiotemporal average value of ambient air PM10 monitored using mass inertial impactor reports relatively higher values (240-372 μg/m(3)) compared to those monitored using RDS (<227 μg/m(3)). In order to realize the severity of mine area pollution, it is compared with PM10 values found in an urban area (Delhi, India). It is found that PM10 values in Delhi (using mass inertial impactor) are much higher (300-400 μg/m(3)) than those reported for the mine environment. The data seems to indicate that the mine environment is relatively cleaner than urban air and therefore raises doubt about the appropriateness of using either mass impactor or RDS for PM10 sampling.
本研究比较了 15 个不同煤矿环境的环境空气中颗粒物（PM10）数据。对于这些煤矿环境中的大多数，监测是由不同的研究人员使用呼吸性粉尘采样器（RDS）进行的，该采样器通过离心惯性分离来分离 PM10。在两个地点——Padmapur 和 Ghugus（印度马哈拉施特拉邦钱德拉布尔）——使用基于质量惯性撞击的采样器进行 PM10 监测。结果表明，使用质量惯性撞击器监测的环境空气中 PM10 的时空平均值报告值相对较高（240-372μg/m³），而使用 RDS 监测的值则较低（<227μg/m³）。为了认识矿区污染的严重程度，将其与在城市地区（印度德里）发现的 PM10 值进行了比较。结果发现，德里（使用质量惯性撞击器）的 PM10 值远高于（300-400μg/m³）矿区环境报告的值。这些数据似乎表明，矿区环境相对比城市空气清洁，因此对于使用质量撞击器或 RDS 进行 PM10 采样的适宜性提出了质疑。
