Abstract

Coal during the present time is one of the dig materials commodity which have giving many contribution in acceptance of state's stock exchange and also have role in national economy wheel. One of the most important area which produce coal is Kalimantan East province. In sub-province region of East Kutai in west part, one part region of Kalimantan East province, representing one area owning interesting coal sediment potency. Geologically this area is including into Hollow of Kutai structured upstate by Tertiary sediment rock series start Eosen till Mio-Pliosen. This research concentration is conducted in district of Muara Wahau, East Kutai. This research aim to know type of litologi in research area, pattern spreading of coal in research area and its quality. Research method in this research is descriptive method and analysis method covering interpretation of logging, profile making, correlation between drilling result, and also cartography of pattern spreading of coal and coal isoquality maps. Primary data has been used are Log Bore data, E-Log data and quality analysis data of coal and some secondary data which consist form of regional geology map and various literature study. Coal exist in research region represent coal which consist of many coat (multiseam) and have typical characteristic intensively splitting at some general especial seam. Pursuant to kinds of coal coat form, hence coal in research area represent coal with fold form. Coal at research area represent the part of Wahau Formation. Pursuant to result of coal classification and calculation by using A.S.T.M standart in bases of dmmf, hence coal as general as 1 research area have rank of sub of bituminous C coal, with ash content 3,32%; total sulphur 0,16%; TM 46,38%; IM 17,89% and calorific value 5212,75 cal / gr. While in seam 2, ash content 5,91%; total sulphur 0,17%; TM 43,89%; IM 15,48% and calorific value 5249,8 cal/gr with sub of bituminous C coal rank.
