GEOLOGI BATUBARA DAERAH TANJUNG ENIM, KABUPATEN MUARA ENIM, PROVINSI SUMATERA SELATAN

Abstract

This paper is based on research results to obtain an overview of the geology of the Tanjung Enim area and its coal potential. Data processing was performed using Minescape 5.7 software.

The research was conducted in an area of ​​52.8 km2. The rock units found can be divided into six rock units, namely the Sandstone Unit, the Claystone Unit including the seven main coal seams in it (coal seams A1, A2, B, B1, B2, C, D), Sandstone Unit - Siltstone including four hanging coal seams. . Sandstone Unit - Tuff, Andesite Intrusion Unit, and Alluvial Deposits Unit. The Claystone Unit and Sandstone Unit - Batulanau are equivalent to the Muaraenim Formation, which is a coal-bearing formation in the study area.

The results of the calculation of coal resources are based on surface mapping data and supported by 27 drill well data belonging to PT. Bukit Asam, Tbk., It was found that the hanging coal seam resource content was 25,570,170 tons and the main coal seam was 1,275,631,640 tons.The coal quality rating in the hanging coal seam is Subbituminous B Coal, A1 coal seam is Subbituminous A Coal while the A2, B, B1, B2, and C coal seam ratings are High volatile C Bitumious.
