✦ Synopsis
The results obtained are shown in Table 1. It can be seen that there is a significant variation in absolute spin concentration within the seam. The spin count rises as the coal becomes progressively more disturbed along the seam, with the highest count occurring within the outburst-prone area. All the values are substantially higher in the disturbed area as compared to the baseline value obtained for normal coal.
Although maceral content varies from sample to sample; 78.8-85.5 ~01% vitrinite and 11.4-17.1 ~01% inertinite, this variation is not considered sufficient to account for the enhanced spin counts observed in the structurally disturbed coal.
These initial results suggest that the coal structure has undergone a breakdown at both the molecular and macroscopic level as a result of tectonic forces applied over geological time. The greater the magnitude and the longer these forces are applied, the more bonds within the coal matrix are broken, thus increasing the mechano-chemical degradations of the coal and consequently increasing the concentration of free radicals.
