Spontaneous combustion – gas evolution

Spontaneous combustion is a principal hazard for the coal industry during production, stockpiling and transport with the occurrence of spontaneous combustion events often leading to severe outcomes and major disruption to operations. To overcome these issues, all mines are required to develop a Spontaneous Combustion Management Plan based on accurate measurements of spontaneous combustion behaviour including the propensity of coal to self-heat under in-mine conditions and the associated gas evolution pattern.

Scientists from the Verum Group led a mine hazards research programme and delivered a new research tool to determine the gas evolution patterns of coal during self-heating events.

The outcome of this culminated in the formation of a joint venture company, CB3 Mine Services Pty Ltd. which provided a range of advanced laboratory tests that are leading practice in quantifying the spontaneous combustion propensity of coal.
