Oxidation and exothermic properties of long flame coal spontaneous combustion under solid-liquid-gas coexistence and its microscopic mechanism analysis.

Science of the Total Environment, 2023
Coal spontaneous combustion (CSC) wastes valuable resources and does great damage to the environment. To study the oxidation and exothermic properties of CSC under solid-liquid-gas coexistence conditions, a C600 microcalorimeter was used to analyze the ...

Investigation of the effect of different distilled water, rainwater and seawater mass ratios on coal spontaneous combustion characteristics.

Science of the Total Environment, 2023
When water comes into contact with coal, the risk of coal spontaneous combustion should be reassessed. In order to analyze the effect of distilled water, rainwater and seawater on the coal self-heating, thermogravimetric analysis (TGA) was applied to ...

Initial exploration on potential fire hazards detection from coal spontaneous combustion applied by acoustic wave.

Science of the Total Environment, 2023
Coal spontaneous combustion often wastes resources and causes environmental pollution. Rapid and accurate identification of high temperature areas in coal is essential to reducing such combustion and environmental pollution.

Study on Coal Spontaneous Combustion Dangerous Zone Under Different Air Leakage in the Shallow Buried Coal Seam Fissure

Combustion Science and Technology, 2023
In the western region of China, the coal seam is shallowly buried. Overburden fissures readily develop upwards through the surface, and provide channels for wind to flow into the gob. Here, a model for the coal spontaneous combustion in gob caused by air

Spontaneous Combustion Liability Indices of Coal

Combustion Science and Technology, 2020
The self-heating of coal due to oxidation potentially leading to its ignition is called “spontaneous combustion.” The liability of coal to undergo spontaneous combustion for selected coal obtained ...

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 ...
