The material classed as “mineral matter” in coal embraces crystalline mineral materials as
well as a range of inorganic elements that occur in non-crystalline form. This review outlines …

Coal mine fires are insidious, persistent, and as widespread as the occurrence of coal itself,
yet their potential adverse human health impacts have been poorly characterised. We aimed …

Soil pollution, influenced by both the natural and anthropogenic factors, significantly reduces
environmental quality. In this study, six hazardous elements (Cr, Ni, Cu, As, Cd and Pb) in 12 …

This paper reports about changes in mobility of hazardous elements contained in coal
during combustion at a power plant in Santa Catarina (Brazil) and the environmental impact …

Composites of physical (superabsorbent hydrogel) and chemical (ascorbic acid) inhibitors
were investigated to ascertain their ability to prevent the spontaneous combustion of coal …

In this study, inorganic geochemical characterization of the thoracic (or< 10 μm) fraction of
road dust in Barranquilla (a major industrial city in the Caribbean region) was conducted …

Long-term spontaneous combustion of coal has caused serious ecological and
environmental problems. Only in recent years has it received growing popularity to …

In this investigation, the coal fires in different Colombian coal mines were studied using
advanced electron beam and X-ray diffraction techniques. The results were compared with …

This study has provided an initial assessment of the environmental impacts and potential
health effects associated with coal fly ash produced during diesel co-firing. Many hazardous …

The secondary oxidation of active groups was studied for crushed coals with various particle
sizes. Then, free radicals of these crushed coals were comparatively analyzed after primary …
