The Lakhra coal has shown the highest HGI value of 66 against 23% of inherent moisture, whereas the Degari and Chamalang coals respectively indicated HGI values of 53 and 32 against 10% and 6.95% of inherent moisture content. It was found that as the inherent moisture in coal increased the HGI values also increased.

2009-01-10The coal when mined contains moisture. The moisture is in two forms. First is the inherent moisture which is entrapped within the structure of the coal. Second is the external moisture that is outside of the coal structure. The amount of moisture depends again on the geographical age, location and condition in the mines.

It has been observed in a series of experiments that the presence of moisture in the coal matrix has profound influences on the gas storage and transport in coal seams by reducing the gas adsorption capacity of the coal, decreasing the gas effective diffusivity through the coal matrix, and varying the coal swelling strain.
