Coal dust explosibility and particle-size distribution [PDF]
"An absorption/desorption model of particle reactivity was employed to describe the observed relationship between two apparently diverse phenomena which have been the subject of considerable study at the U.S. Bureau of Mines, viz.

Major factors influencing local dust radiative forcing [PDF]
In conclusion, it is shown in this paper that surface albedo variations over desert regions can have a significant influence on the solar and net radiative forcing of desert dust.

ABSTRACT Although the global expansion of oxygen‐depleted marine environments during the Early Toarcian Jenkyns Event (or Toarcian Oceanic Anoxic Event) is primarily inferred from successions in the NW European epicontinental basins, the timing of the expansion of anoxia in Tethyan basins, where hydrography potentially played a minor role, is poorly ...

Wall effects in particle-laden flows [PDF]
The aim of this study is to investigate about the complex phenomenology associated with the interaction of a particle-laden turbulent flow with the slag-covered wall of an entrained-flow gasifier.

Study on the Explosion Mechanism of Low-Concentration Gas and Coal Dust
In coal mines, the mixture of coal dust and gas is more ignitable than gas alone, posing a high explosion risk to workers. Using the explosion tube, this study examines the explosion propagation characteristics and flame temperature of low-concentration ...

The Unexpected Discovery of Paleocene? Coals in Outcrops Thought to Be Cambrian, Al Huqf, Oman
ABSTRACT Two brown organic deposits were encountered whilst investigating kaolinitic claystones thought to occur at the base of a Cambrian formation at outcrop. The age of these organic deposits is probably Paleocene from palynology. Organic petrography shows that they are subbituminous coals with some oil source potential.

Associations between outdoor air pollution and cancers other than lung cancer remain unclear, particularly in the context of tobacco use. Here, the authors assessed possible links between ambient air pollutant exposure and incidence of 20 non‐lung cancers among adults followed over a 25‐year period in the United States.

Experimental Research on Bituminous Coal Dust Explosibility
:In order to evaluate and control the hazards of coal dust explosion in coal mines and power plants, the explosion characteristics of bituminous coal dusts were tested in a Siwek 20 litre spherical vessel.

Research on dust control mechanism of coal baffle based on CFD-DPM model
The fully mechanized mining face is among the most critical areas for dust pollution within a mine, in large mining height faces, the elevated coal fall height during the mining process facilitates the dispersion of particulate matter from the coal ...
