Effects of pyrite on the spontaneous combustion of coal

The combustion of coal is the largest contributor to the human-made increase of CO 2 in the atmosphere. Electric generation using coal burning produces approximately twice the greenhouse gasses per kilowatt compared to generation using natural gas.

Understanding waste rock spontaneous combustion –

Spontaneous combustion has always been recognised as a principal mining hazard in the coal mining industry, particularly in underground mines where several major coal mine explosions have been attributed to initiation of a flammable gas mixture by a spontaneous combustion event. Recent outbreaks of

The adiabatic oven testing developed provides a rapid method of quantifying the mutual effect of the pyrite/moisture/oxygen reaction so that appropriate hazard maps are developed to assist with mine planning and spontaneous combustion management.

STAGES OF SPONTANEOUS COMBUSTION One recognizes three stages of spontaneous combustion of coal in coal mines: •the incubation period •the indication period •open fire 1. The incubation period •It is the period between the onset of first oxidation and the timepoint when one can detect by the senses.

Preventing Spontaneous Combustion in Stored Coal Hugh quantities of coal are stored in bunkers, silos, hoppers and open air stockpiles. How susceptible such stocks of coal are to fire from spontaneous combustion depends on a number of factors, from how new the coal is to how it is piled. Recommendations: Know your coal.

The presence of pyrite (FeS2) in coal can cause or contribute to several problems for the coal mining industry. These problems, which include spontaneous combustion, roof falls, floor heave, and accidental explosions in coal surface mining when ammonium nitrate-fuel oil (ANFO) explosives are used, result from pyrite oxidation.

Spontaneous combustion (spontaneous and is known to have several negative effects on coal. •A significant contribution may be the oxidation of pyrite to

Spontaneous combustion is a potential source of greenhouse gas emissions from open-cut coal mines. Emissions, however, are very variable across the industry; many mines have no instances of spontaneous combustion
