Formatted abstract
All underground coal mines are required by legislation to develop a Spontaneous Combustion Management Plan (SCMP). Assessing the propensity of coal to spontaneously combust is a key component of this plan. Therefore the data used as input to this assessment must be accurate and representative of the mine situation. 

Coal roof samples have been adiabatically tested to assess the effects of pre-oxidation. R70 self-heating rate values progressively increase with distance above the roofline. The samples taken furthest from the mine roof, and thus the freshest samples show a more than doubling of the self-heating rate compared with a sample taken at the roofline. These findings have major implications for rating the spontaneous combustion propensity of the coal and demonstrate the need for controlled sampling procedures to develop an accurate SCMP.
