Sample intervals are shown on Figure 3. Proximate data are percentages on an as-received (as) and dry basis (db) except BTU (British Thermal Units) and Kcal/kg. Trace element data is on a whole-coal basis. S. No. = sample number; Moist = moisture, S = total sulfur; Ss = Sulfate sulfur; Sp = pyritic sulfur; So = organic sulfur; ND = no data; Sample locations are given in Appendix I.
