The thesis title is “An analysis of gas emissions during a spontaneous combustion coal heating event tested by 2m column method”. The objective is to map gas emissions from an Australian bituminous coal during a spontaneous heating event in. The vehicle of data acquisition is an intensive gas sampling program using quad graph chromatographic analysis to sample gas emissions during two separate heating events in the 2m column.
This thesis looks at issues of spontaneous combustion with particular attention paid to analysis of gas emissions. Two tests are to be run with this purpose in mind with gases sampled at more points than in any previous 2 metre column test.
Given the nature of spontaneous combustion in coal, the time duration of the tests is not known prior to test commencement so sampling points of gas emissions are temperature motivated. Both experiments were sampled for gases through a temperature range of between 300C and 2400C.
