Atmospheric aerosols have effects on atmospheric radiation assessments,global climate change,local air quality and *** particular,aerosols are more likely transformed and accumulated in *** this paper,we used the Multi-Axis Differential Optical Absorption Spectroscopy(MAX-DOAS)instrument to study the characteristics of aerosol type and contributions of PM_(2.5) chemical components to aerosol extinction(AE),vertical distribution of aerosols,and *** December 30,2018 to January 27,2019,we conducted MAX-DOAS observations on *** proportion of PM_(2.5) to PM10 was 69.48%-95.39%,indicating that the aerosol particles were mainly fine *** analyzing the ion data and modifying Interagency Monitoring of Protected Visual Environments(IMPROVE)method,we found that nitrate was the largest contributor to AE,accounting for 31.51%,28.98%,and 27.95%of AE on heavily polluted,polluted,and clean days,***4+,OC,and SO42-were also major contributors to *** near-surface aerosol extinction retrieved from MAX-DOAS measurement the PM_(2.5) and PM10 concentrations measured by an Unmanned Aerial Vehicle(UAV)have the same trend in vertical *** increased about 3 times from surface to 500 *** the backward trajectory of the air mass during the haze,we also found that the continuous heavy pollution was mainly caused by transport of polluted air from the northeast,then followed by local industrial emissions and other sources of emissions under continuous and steady weather conditions.

The internal mechanism of the high hydrophobicity of the coal samples from the Pingdingshan mining area was studied through industrial,element,and surface functional group *** testing and molecular dynamics simulations were employed to study the impact of three types of surfactants on the surface adsorption properties and wettability of highly hydrophobic bituminous *** results show that the surface of highly hydrophobic bituminous coal is compact,rich in inorganic minerals,and poorly wettable and that coal molecules are dominated by hydrophobic functional groups of aromatic rings and aliphatic *** wetting performance of surfactants as the intermediate carrier to connect coal and water molecules is largely determined by the interaction force between surfactants and coal(Fs-c)and the interaction force between surfactants and water(Fs-w),which effectively improve the wettability of modified coal dust via modifying its surface electrical properties and surface energy.A new type of wetting agent with a dust removal rate of 89%has been developed through discovery of a compound wetting agent solution with optimal wetting and settling *** paper provides theoretical and technical support for removing highly hydrophobic bituminous coal dust in underground mining.
