Potensi Sumberdaya Batubara di Daerah Petak Malai, Kabupaten Katingan, Provinsi Kalimantan Tengah
Abstract: Administratively,
research area ( 9.930 Ha) is located at Petak Malai District, Katingan Regency,
Central Kalimantan Province. This research is aimed to know the coal outcrop
position, the number of coal seam and to measure of coal resources. The
research is done by geological mapping of coal and other lithology at the
field. The next phase is correlate some of coal outcrop and make a geological
map. The last phase is calculating measured resource and indicated resource of
all coal seams.There are ten of coal outcrops in the research area. The ten
coal outcrop can be correlate and it becomes three coal seams which have 0.13 m
to >0.7 m thick. This coal outcrop is found at Claystone-Sandstone Unit of
Dahor Formationwhich lies at central part of the research area. Measured
resource of coal resources calculation of research area is 873,050.1 ton.
Indicated resource of this research area is 4,524,346 ton.Geological structure
formed in the study area is fold and joint. The fold axis is relatively
north-south trend. Anticline and syncline fold are the main control of the coal
spread.
