Analyzing Characteristics of Particulate Matter Pollution in Open-Pit Coal Mines: Implications for Green Mining

The particulate pollution in the open-pit coal mines of China is particularly severe winter. aim this study to understand characteristics matter (PM) winter and provide a basis for prevention control pollution. We took problem PM concentration at bottom Haerwusu Open-pit Coal Mine (HOCM) as research object. Dust monitoring equipment two measurement points different heights were positioned continuous concentration. data three months gathered. Statistical analyses performed analyze variation its relationship with meteorological factors. results show that average area below daily limit National Ambient Air Quality Standard (GB 3095-2012). However, PM10 exceeded national December. order observed December > January February. correlation found be positive humidity negative wind speed. Temperature positively correlated December, while it January. At same time, temperature difference negatively Under combined action multiple factors, magnitude impact on pit speed (inverse intensity). In conclusion, PM2.5 more sensitive environmental are useful progress green mining.
