Spontaneous combustion remains a significant safety and environmental risk in abandoned stockpiles, spoil heaps, and post mining deposits containing reactive carbonaceous materials. This study presents an integrated framework for the assessment and prediction of spontaneous combustion risk based on the combined use of long term monitoring data, statistical trend analysis, and physically based numerical modelling, developed in line with the preventive principles of the FRAM concept.\r\nA three dimensional numerical model is employed to describe coupled heat and mass transfer in a porous reactive body, explicitly accounting for oxygen transport, low...
