Abstract

The research area is located in Mangkalapi, Kusan Hulu District, Tanah Bumbu Regency, South Kalimantan and
based on its physiography, this area is included in Asem-Asem Basin. The research area is known to be prospect
of coal in which coal-bearing formation in this area is Warukin Formation that consist of claystone, shale carbon,
sandstone, and coal itself that aged Early Miocene to Late Miocene. This study focuses on Pit Z which nowadays
is being developed and ecomonic to be mined. Therefore, the goal of this research is to know about the geological
condition of the area such as its geomorphology, stratigraphy, geological structure, and also coal reserves that
is economic to be mined. The used method in this research is descriptive and analytical method that integrate
between field data and laboratory test.
Geomorphology of this area is made up of two origin landform in which denudasional landform consist of
undulating landform and peneplain, and antropogenic landform consist of mined pit, disposal area, sump, and
coal storage area. The stratigraphy, from the oldest to youngest, are Warukin Claystone Unit that aged Early
Miocene to Middle Miocene and Warukin Sandstone Unit that aged Middle Miocene to Late Miocene. Both units
shows that their depositional environment is Transitional Lower Delta Plain. Method that used to calculate coal
reserves on Pit Z is Cross Section method and Block Method. The result of the calculation from cross section
method is 2,695,770.58 mT with stripping ratio 3,72, while calculation result of coal reserves using block method
is 2,678,897.74 mT with a stripping ratio of 3.47.
