Dust emission in powder handling: Free falling particle plume characterisation [PDF]

, 2009
Dust generation during solids handling, principally from the free falling of bulk materials and their impact on stockpiles, can be a health threat for operators and a cause of dust explosions.

Experimental study on the effect of biopolymer suppressant application rate on dust suppression efficiency for mine tailings

Results in Engineering
Dust emission is a serious environmental issue in mine tailing management. The most commonly used method for dust control is water spraying. However, the efficiency of pure water is relatively low due to the high evaporation rate, especially in arid and ...

Global dust model intercomparison in AeroCom phase I [PDF]

, 2011
This study presents the results of a broad intercomparison of a total of 15 global aerosol models within the AeroCom project. Each model is compared to observations related to desert dust aerosols, their direct radiative effect, and their impact on the ...

Molecular simulation study on effect of mine water hardness on foam stability

Meitan kexue jishu
Mine water contains a large amount of hard water ions, and as the main water used in foam dust suppressants, its water hardness is crucial to the dust removal efficiency and economic costs of foam dust suppressants.

Evaluation index of wind resistance performance of dust suppressant and its application

矿业科学学报
This study proposes three evaluation indexes for evaluating the wind resistance of mine dust inhibitors, namely average loss rate per unit mass (ALRPUM) of dust suppressant, average suppression rate per unit mass (ASRPUM) of dust suppressant, and ...

Evaluation of the performance of surfactants on bituminous coal dust suppression by using microscopic molecular dynamics simulation and macroscopic experimental tests

International Journal of Coal Science & Technology
The development of mechanization of the coal mining industry has dramatically increased coal production. However, a significant amount of coal dust is generated during production which results in a hazard for the underground miners to overexposure to a ...
