Identifikasi Sebaran Batubara Berdasarkan Nilai Resistivitas Batuan Konfigurasi Wenner Desa Sungai Buluh Kecamatan Muara Bulian Kabupaten Batanghari

Abstract

Research on the distribution of coal based on rock resistivity values was carried out in the mining business permit area of PT Sentosa Prima Coal, in Sungai Buluh Village, Muara Bulian District, Batanghari Regency, Jambi Province. Data obtained from field measurements using geophysical methods. Geophysical data acquisition method used is the resistivity geoelectric method with the Wenner configuration. The rock characteristics in the research area in Sungai Buluh Village are the same as the rock characteristics of the Muara Enim formation. Where the layer content consists of clay rock, sandstone and subbituminous coal. The potential for coal is found on all trajectories seen from the resistivity value of 129-200 Ωm at a depth of ± 21 meters with a thickness of 4-8 meters. Subituminous is considered a medium grade coal because of its relatively low / not very high thermal temperature. Subbituminous is coal that lies widely in the estuary Enim formation where Sungai Buluh Village is located in this formation.
