Abstract

Administratively the study area is located in Tegalrejo Village, Lawang Kidul District, Muara Enim Regency,
South Sumatra Province, with coordinates X1: 374251 Stratigraphically the study area is in the South Sumatra
Basin, the Muara Enim Formation which has a lithology dominated by claystone, and scattered several
lithologies such as glauconite sandstones with a flarer structure, siltstone and coal. It is interpreted that this
area is experiencing a process of sedimentation in the lower delta plain environment (Allen & Chambers, 1998).
This study aims to determine the geological conditions in detail in the study area in the form of drainage
patterns, geomorphology, stratigraphy, geological structure, and depositional environment as well as knowing
the estimated coal resources. This research method is conducting field observations to obtain geological data on
the surface as well as secondary data processing in the form of actual contours and contours of the coal
structure. The geomorphology of the study area consists of undulating hilly, mine openings, and water sump. The
stratigraphy of the study area was composed by the Muaraenim Claystone Formation which was deposited
during the Late Miocene (Ginger & Fielding, 2005). In the research area there are geological structures,
namely the Left Slip Fault Normal Fault (Rickard, 1972) and Left Thrust Slip Fault (Rickard, 1972). Estimation
of coal resources using the cross section method yielded 4,213,118 tonnes of D seam and 6,476,089 tonnes of E1
seam coal, for a total of 10,689,207.17 tonnes. Overburden calculation results obtained a result of
184,106,371.5 m3.
