//&#;&#;The mine had been dealing with major spontaneous combustion (Spon Com) and dust management issues and was looking for a targeted approach to mitigate and manage hot areas. With significant loss of non-blasted material in , which directly affected production targets, initiatives were required to reduce lost blasted ground and to reduce the effect of Spon Com on site.
The coal is hosted within a Triassic sedimentary sequence, underlain by Pre-Cambrian basement and occurring within four distinct lobes (Parkin ). The coal within Lobe B was deposited in three series termed Upper, Main and Lower Series (Figure ). Risk profiling and control of spontaneous combustion for coal mine closure B Williams et al.
The risk of dust, smoke and odours from spontaneous combustion in coal stockpiles at the site are low. Performance Measures In accordance with Schedule , Part B, Condition B(c) of SSD , a performance measure for spontaneous combustion is to minimise the risk of spontaneous combustion on the site. In accordance
//&#;&#;The three stages division of coal spontaneous combustion is fuzzy and lacks adequate risk and warning levels corresponding to its divisions; additionally, the targeted prevention measures for each stage have not been described. To address the shortcomings of the three stages division, the five stages division was proposed to more clearly analyze the stage changes of the ...
//&#;&#;This information can be used to fine tune monitoring systems to give an early warning well in advance of a potential combustion or explosion event. Spontaneous combustion management plans (SCMPs), which incorporate coal assessment as well as local and site-specific parameters, are becoming increasingly important in the coal industry to the point that they are becoming a legal
spontaneous combustion - Oxidisation of coal is a normal process and this produces heat and certain gases. (All coal oxidizes). Spontaneous combustion is the process by which certain materials can ignite as a result of internal heat which arises spontaneously due to reactions liberating heat faster than it can be lost to the environment
Development of a spontaneous combustion principal hazard management plan for underground coal mining operations . Fundamentals of spontaneous combustion Spontaneous combustion describes the process of self-heating of coal by oxidation. After exposure by mining, coal undergoes a continuous exothermic oxidation reaction when exposed to air.

//&#;&#;The majority of test methods for assessing the coal spontaneous combustion hazard do not capture the full self-heating behaviour of the coal under normal mine conditions. Primarily, these laboratory tests provide at best an indication of the intrinsic reactivity of the coal, although many of them are performed at high temperatures in the thermal runaway region and are more indicative of the ...

Spontaneous Combustion is recognised in both NSW and Queensland as a specific hazard that must be managed. The legislations outline the processes to be followed to achieve this management. The focus of this book is Australian underground coal mining but it also refers to international best practice and research when relevant.
Mining Product: SponCom - Spontaneous Combustion Assessment Software. SPONCOM is software to aid mining operators, regulatory bodies, and consultants in the assessment of the spontaneous combustion risk of an underground mining operation. The DOS-based SPONCOM expert system was originally developed by the US Bureau of Mines (USBM).

The Leigh Creek coal mine, located approximately km north of Adelaide in South Australia, operated between and . The coal at Leigh Creek mine is a low rank, sub-bituminous brown coal that is prone to self-heating and spontaneous combustion.Spontaneous combustion has occurred in the spoil piles throughout the decades of the mining operation.
Mine fires and spontaneous-combustion control. The risk of fires and explosions is a major safety concern in underground coal mines, with catastrophic consequences if robust monitoring and control measures are not in place to deal with this complex hazard.
