A REVIEW OF SPONTANEOUS COMBUSTION OF COALS

Fuel Science and Technology International, 1995
ABSTRACT Coal is one of the carbonaceous materials which, under certain conditions, can combust spontaneously as a result of its oxidation with atmospheric oxygen. Coal oxidation is an irreversible exothermic reaction and its rate increases with temperature.

Preparation of Vapor–Gel and Its Synergistic Mechanism for Moisture Retention and Oxygen Barrier in Preventing Spontaneous Combustion of Coal

Journal of Applied Polymer Science
To mitigate the risk of spontaneous combustion, which is intensified by the prolonged exposure of abandoned coal in the goaf to a high‐oxygen environment during the mining of shallow‐buried, close‐range coal seam groups, a novel aerosol gel based on a ...

Experimental study on the effect of preinhibition temperature on the spontaneous combustion of coal based on an MgCl2 solution

Fuel, 2020
Disasters from the spontaneous combustion of coal seriously affect safe coal mine production. Halogen salt inhibitors have been widely used as materials specifically to prevent and control the spontaneous combustion of coal.

CO release characteristics of coal spontaneous combustion in low-temperature oxygen-deficient environments: Coupling effects of temperature, oxygen concentration and time.

Journal of Hazardous Materials
CO is a colorless, odorless, and toxic atmospheric pollutant. CO is produced at low temperatures from coal residues in underground mining goaf and is emitted into the atmosphere.

Research Progress and Visualization Analysis of Spontaneous Combustion of Water-Immersed Coal

Combustion Science and Technology
One of the most catastrophic events that can occur during coal mining is a fire triggered by spontaneous combustion of the coal. Due to complex geological conditions, some coal mines in China have the characteristics of shallow burial and small spacing ...

SPONTANEOUS COMBUSTION OF COALS IN PERMAFROST CONDITIONS

TRANSBAIKAL STATE UNIVERSITY JOURNAL, 2022
Taking into account the prospects for the growth of coal production in the conditions of the North-East, the countries require further development of research to more reliably justify measures to prevent endogenous fires in the permafrost zone, which cause serious economic damage and worsen the environmental situation due to the release of large ...

Mechanochemical evolution of coal microscopic groups: A new pathway for mechanical forces acting on coal spontaneous combustion.

Science of the Total Environment
Coal spontaneous combustion (CSC) remains a significant threat to regional ecological environments. As coal mining operations extend deeper into the earth, the increasingly complex mechanical force conditions in deep-seated mines escalate the potential ...

Fire prevention and control using gel-stabilization foam to inhibit spontaneous combustion of coal: Characteristics and engineering applications

, 2020
In order to address the issue of spontaneous combustion in coal mines during the mining process, we have proposed gel-stabilized foam (GSF) that can prevent and control fires in coal mines.
