Experiment Research of Coal’s Spontaneous Combustion Characters
Advanced Materials Research, 2014On the basis of physical oxygen uptake, use the instrument to identify the spontaneous combustion of Yang quan coal, and combination the insulation oxide of coal as well as the TG-DSC experiment to analysis of low-temperature oxidation of coal, though the DSC curves, combined with the insulation oxide experimental to analysis the size of the heat.

Study on Spontaneous Combustion of Coal Underground
Journal of the Fuel Society of Japan, 1957石炭の自然発火は現在まで主として化学的の面より研究されてきたが炭鉱内においておこる坑内自然発火の場合はその原因になる因子が非常に多く, この原因を発見することが困難である。従つて自然発火の早期発見も困難であつた。自然発火の早期発見に関しては現在まで臭気, 湿度の変化, 温度の上昇, 特殊指示ガスなどがその要素となつていたが, これらの方法はいずれも適確な予知ができず, また発見された時はもうすでにかなり自然発火が進んでいるという状況である。筆者は本文中において温度変化による発見の方途を一歩進めて炭層温度, 炭壁温度, 気流温度の相関関係から自然発火を予知する方法を述べるとともに, アスファルト乳剤塗布による自然発火防止の基礎実験について述べる。

Theories on Spontaneous Combustion of Coal
1993Kömürün kendiliğinden yanması, tüm kömür üreticisi ülkelerin karşılaştığı en önemli sorunlardan biridir. Bu konunun nedenini saptama çalışmaları daha önceki yüzyılda başlamıştır. Bu sorunun nedeni hakkında çeşitli kuramlar ileri sürülmüş olup bu kuramlar şu şekilde sıralanabilir: - pirit kuramı, - bakteri kuramı, - oksidasyon kuramı ve - nem kuramı. Bu

A REVIEW OF SPONTANEOUS COMBUSTION OF COALS
Fuel Science and Technology International, 1995ABSTRACT 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.

SPONTANEOUS COMBUSTION OF COAL AND EFFECTING FACTORS
2018Coal tends to adsorb oxygen and oxidize due to its structure. Spontaneous combustion mechanismof coal is very complicated, and still this mechanism is not completely understood. However, coaloxygencompound theory is widely accepted by researchers nowadays.
