Spontaneous Combustion in Open-Cut Coal Mines:

2015-1-1  Most of the coal mined in Australia is produced by open-cut methods. In 2010–2011, for example, the total Australian production of black coal was about 405 Mt with roughly three-quarters coming from open-cut mines (Australian Coal Association, 2013).Hence, there is considerable potential for spontaneous combustion to occur in spoil over large areas.
