ECOLOGY AND COAL QUALITY
Pressure and heat associated with an indigenous intrusion has increased at Bungkukan to high-volatile bituminous coal at a total of 12 seams range in thickness from 1m to 12m, typically in the range of 2.4m to 4.5m. Seam dips vary from 3º to 20º at the outcrop. The seams are very clean in terms of mineral matter and sulfur and, at 5-9% in some areas, the in situ moisture content is low.The operation produces some main export product. Coal with high – volatile bituminous steam coal with high calorific value, very low ash, low sulfur and low total moisture against coal that is similar in specifications but with a higher moisture content
