Abstract

General geological investigation activities and detailed exploration need to be carried out, so that it can show potential coal resources that can still be developed. The research area is in the PT. Berau Coal concession area, administratively located in Berau Regency, East Kalimantan Province. The research method used in calculating resources in Region 'X' is the Polygon Method, namely by halving the distance between two sample points on one axis to produce an area of ​​influence and refers to moderate complexity based on analysis of the geological conditions of the research area (SNI 5015:2019). This research aims to determine the feasibility of a coal seam to be mined based on aspects of dimensions, quantity and quality of coal distribution, as well as a reference in design and determining appropriate mining methods based on coal geological modeling. Based on ASTM D388-19 of 2004, the research area has a High Volatile B Bituminous coal ranking with an average calorific value (dmmf) of 13111,01 Btu/lb, ash content 4,7%, total sulfur 0,98%, total moisture 21,28%, inherent moisture 16,66%, volatile matter 48,63%, and fixed carbon 51,37%. The total estimated coal resources in the research area are 14.760.000 million tons, consisting of total measured coal resources of 13.380.000 million tons, indicated 930.000 thousand tons, and inferred 410.000 thousand tons.

Abstract

Coal is a fossil energy source that is widely available in the world, including Indonesia. Indonesia is one of the ten largest coal producing countries in the world. One area that has coal reserves is Berau Regency, East Kalimantan Province. The research location is in the concession area of PT. Berau Coal which covers the Binungan, Lati, Sambarata, Birang, Punan, Kelai, Gurimbang and Parapatan areas. Administratively, the research location is located south of Gurimbang Village, Sambaliung District, Berau Regency, East Kalimantan Province. The aim of this research is to analyze the geological conditions and distribution of Seam X coal in the North Gurimbang area, Berau Regency. To achieve this goal, methods are used, namely activities in the field and studio. Activities in the field include collecting data on the position of rocks through field geological surveys. Field geological surveys are to determine the geological conditions of the research area in the form of the constituent rocks, stratigraphic relationships, factors that form morphology and geological structure. Activities in the studio involve analyzing subsurface data. The results and discussion show that the geomorphology of the research area is divided into three geomorphic sub-units, namely swamp plains, denudational hills and mine openings sub-units. The stratigraphy of the study area is grouped into three informal rock units, in order from old to young as follows: sandstone units, mudstone units and alluvial deposit units. The distribution of the seam The distribution pattern of seam
