Abstract One of the challenges in the coal mining industry is self-heating of coal as this can become a problem during mining operations, stockpiling and transportation. This study reviews the mechanism of self-heating, areas of spontaneous combustion, various factors influencing self-heating and different experimental studies to predict its occurrence. The technical control measures applied to minimise self-heating with special consideration to South African coals are also discussed. The… Expand
A review of research on spontaneous combustion of coal
Abstract Coal oxidation at low temperatures is the heat source liable for the self-heating and spontaneous combustion of coal. This phenomenon has imposed severe problems in coal related industries.Expand
Influence of antioxidants on spontaneous combustion and coal properties
Abstract Spontaneous combustion (SPONCOM) of coal is well known to be a serious threat to the safety of mineworkers, mining equipment and to the environment. It is also the biggest reason behind theExpand
Spontaneous combustion liability of coal and coal-shale: a review of prediction methods
This study presents a review of the various methods to predict the spontaneous combustion liability of coal and coal-shale. The relative propensity of coal to undergo self-heating can be establishedExpand
Investigation of the effect of reactor size on spontaneous combustion properties of coals with different coalification degrees
The spontaneous combustion of coals is a natural phenomenon that causes serious losses in the mining sector as well as environmental problems as a result of greenhouse gases released duringExpand
Spontaneous combustion liability between coal seams: A thermogravimetric study
Abstract The spontaneous combustion liability of coal can be determined by using different experimental techniques. These techniques are well-known in their application, but no certain test methodExpand
A study of fire propagation in coal seam with numerical simulation of heat transfer and chemical reaction rate in mining field
Abstract Spontaneous combustion of coal is a problem that affects the mining operation and generates environmental, economic, social and geotechnical impacts. This phenomenon has been divided intoExpand
Experimental study on the simultaneous effect of long-term water immersion and pyrite content on spontaneous combustion liability of Ömerler coals (Kütahya, Western Turkey)
Spontaneous combustion of coals is a natural phenomenon that causes serious losses of human life, ceasing mining activities and serious environmental problems (e.g., emission of toxic gases).Expand
The Mechanisms of Endogenous Fires Occurring in Extractive Waste Dumping Facilities
The processes of hard coal extraction and processing are accompanied by the generation of a considerable amount of post-mining extractive waste, which in most cases is deposited on the groundExpand
On the dependence of predictive models on experimental dataset: a spontaneous combustion studies scenario
ABSTRACT Spontaneous combustion has been a long-standing challenge affecting coal mines globally as it jeopardises the financial and safety aspect of mining operations. It does not only damage assetsExpand
Influence of organic and inorganic properties of coal-shale on spontaneous combustion liability
Abstract Coal and coal-shale undergo low-temperature oxidation when exposed to air, potentially leading to spontaneous combustion. Coal-shale found in association with coal seams vary considerably inExpand
