Abstract

This research is located in Darmo, Muara Enim, South Sumatra, while in geological spatial it is located in the Muaraenim Anticlinorium zone. The purpose of this study is to build a geological model including the stratigraphic sequence and reconstruction of geological structures, modeling coal geometry and calculating coal resource estimates in the study area. The methods applied in this study include field observations, laboratory analysis and studio analysis. Coal geometry modeling is doing by krigging method (omnidirectional and gridding), as well as the calculation of coal resources using the circular method. The results obtained from this study are in the form of stratigraphic sequence of the youngest namely the Kasai Formation and the Muaraenim Formation. Geometry of coal seams in the study area has a thickness that is quite varied from 0.5 meters - 12.8 meters, in general is continuous, has the characteristics of the roof and floor in the form of sandy coal and muddy coal and interburden in the form of sandstone and claystone. The form of coal seams in the study area is included in the classification of horse back, fault and fold. Estimated coal resources in the study area consist of inferred resources 74677959 m3 or equivalent to 104549142 tons, designated resources 69043012 m3 or 96660216 tons and measured resources 68041837 m3 or 95258571 tons which is a calculation of estimated coal resources from seam A, seam B, seam C and seamless C and seam D.
