- Abstract
Objective: To identify if the susceptibility to spontaneous combustion changes is related to the influence of the concentration of surface sodium as a result of the proximity of coal beds to coastal areas. Methodology: Samples were taken from open-cast mining coal from areas located in different parts of Colombia, determining their susceptibility to spontaneous combustion by their historical records, then analyzing the concentration of sodium on the surface of the coal which was obtained using a solution composed of HCl and HNO3 in concentrations of 50%, respectively, and the susceptibility and coastal proximity relationship was determined. Results: It was found that there is not a direct relationship between the amount of sodium, present in the surface, and the susceptibility of coal, in turn, there is no correlation of the data of surface sodium concentration and the distance of the mantles to the coasts which allowed to demonstrate that the theory of ionic compounds does not impact the spontaneous combustion of coal. Conclusions: The variation of the data of the surface sodium concentration on the amount of susceptible and non-susceptible beds correspondingly in a 15% that shows the susceptibility, has neither a relation to the concentration of sodium in the surface of the samples, nor to a proximity to the coast.
