Abstract

Secara Geologi, Batubara terbentuk melalui proses yang kompleks dalam artian harus di kaji dari berbagai sudut. Pemebentukan batubara di cekungan batubara umumnya mengalami deformasi oleh gaya tektonik sehingga membentuk lapisan batubara dengan bentuk tertentu. Geometri lapisan batubara merupakan hal yang sangat penting di dalam penentuan sumber daya atau cadangan batubara, pola sebaran dan kemenerusan lapisan batubara merupakan parameter di dalam geometri lapisan batubara. Pola sebaran dan kemenerusan lapisan batubara yang bervariasi dikendalikan oleh proses-proses geologi yang berlangsung bersamaan atau setelah pembentukan batubara. Penelitian ini bertujuan untuk mengetahui kondisi geologi yang meliputi aspek Geomorfologi, Stratigrafi, Struktur Geologi dan menghubungkan keterkaitan pola sebaran serta kemenerusan lapisan batubara dengan keadaan geologi. Berdasarkan hasil pengamatan lapangan dan laboratorium, menganalisis sampel batuan dengan menggunakan sayatan batuan petrografi untuk mengetahui mineral yang terkandung dalam batuan, analisis geologi struktur berupa kekar yang terdapat pada batubara untuk mengetahui arah tarikan dan arah lepasan, analisis lipatan menggunakan metode higgisns dan busk. Hasil Penelitian menunjukan bahwa secara geomorfologi terdapat 6 bentuklahan yaitu Galian Tambang (A1), Timbunan Tambang (A2), Sump (A3), Dataran Denudasional (D1), Perbukitan Struktural (S1), dan Lembah Sinklin (S2), Stratigrafi terdapat 2 satuan batuan yang termasuk kedalam formasi Muaraenim. Kata kunci: Batubara, Pola Sebaran serta kemenerusan, Geologi, Muaraenim Geologically, coal is formed through a complex process, meaning it must be studied from various angles. Coal formation in coal basins generally experiences deformation by tectonic forces to form coal seams with certain shapes. Coal seam geometry is very important in determining coal resources or reserves, the distribution pattern and continuity of coal seams is a parameter in coal seam geometry. The varying patterns of distribution and continuity of coal seams are controlled by geological processes that occur simultaneously or after coal formation. This research aims to determine the geological conditions which include aspects of Geomorphology, Stratigraphy, Geological Structure and to relate the relationship between distribution patterns and continuity of coal seams with geological conditions. Based on the results of field and laboratory observations, analyzing rock samples using petrographic rock incisions to determine the minerals contained in the rocks, structural geological analysis in the form of joints found in coal to determine the direction of tension and release, fold analysis using the higgisns and busk methods. The research results show that geomorphologically there are 6 landforms, namely Mining Excavations (A1), Mining Piles (A2), Sumps (A3), Denudational Plains (D1), Structural Hills (S1), and Syncline Valleys (S2). There are 2 stratigraphic units. rocks belonging to the Muaraenim formation. Keywords : Coal,Dstribution pettern and continuity, Geology, Muaraenim.
