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...

SURFACE STABILISATION FOR THE PREVENTION OF SPONTANEOUS COMBUSTION IN COAL SPOIL HEAPS: LABORATORY AND SEMI‑INDUSTRIAL EVALUATION

iSET Journal X:X

Spontaneous combustion of coal spoil heaps and post‑mining waste dumps represents a persistent environmental and safety challenge in many European coal regions. One of the key mechanisms driving self‑heating processes is the unrestricted access of oxygen to coal‑bearing materials deposited at the surface of spoil heaps. Surface stabilisation treatments therefore represent a promising preventive approach to limit oxidation processes and reduce the risk of smouldering and endogenous fires. \r\nThis study presents the results of laboratory and semi‑industrial investigations aimed at evaluating the effectiveness of selected surface...
