The generalised stratigraphic column showing seam nomenclature is on Figure 2. Average seam thickness per seam by block is shown in Tables 4.1 and 4.2 below. The seams are folded around a north plunging syncline, with dips of 10-15 degrees steepening towards the flanks of the syncline. A number of representative cross-sections for each block are shown on Figure 3 and Figure 4.

4.2 Coal Quality

The coal is very high energy average 7,210 kcalkg gar and medium ash 6-7 adb bituminous coal with variable sulphur content 0.4-3.3 adb with an average of 1.5 adb at Keham and 1.2 adb at Cilong. Average coal qualities for both blocks are given in Tables 4.3 and 4.4. A number of drill holes are “touch” cored and samples were submitted for analytical testwork, which typically included Total Moisture, Proximate Analysis, Total Sulphur, Calorific Value and Relative Density test work. “Touch” coring results in some coal loss at the seam roof, therefore in thinner seams there may be a degree of sample bias.
