Abstract
This research aims to determine the role of coal facies and the value of pore fractal dimensions on changes in the adsorption of coal methane gas. This study location is in the Arang Alus area, Binuang District, Tapin Regency, South Kalimantan Province. As many as 4 (four) coal seams were observed, namely, seam D (oldest layer), C, B, A (youngest), each seam was sampled using the Channel Sampling method. The method for determining the facies of coal uses maceral, for calculating the value of the pore fractal dimensions using the box counting method, while gas adsorption using the Adsorption Isotherm method is carried out in Lemigas Jakarta, Indonesia. Based on the analysis of coal facies, seams D and B are included in the Fen facies, seams C and A are included in the Wet Forest Swamp facies. The value of the pore fractal dimensions of seam D and B = 1.91 – 1.92, the value of the pore fractal dimension is 1.895 – 1.896, while the adsorption volume of methane gas in seam D and B coal = 425 – 315 Scf/ton, seam C and A = 214 Scf/ton and 431 Scf/ton. The changes in coal facies from Fen to Forest Wet Swamp affect the changes in pore fractal dimension values and adsorption of coal methane gas. Coal in the Fen facies has a pore fractal dimension and the adsorption of methane gas is greater than in the Wet Forest Swamp facies. Mineral matter is a contaminant in the Fen facies which can cause reduced adsorption of methane gas. Keywords: Facies, Fractal Dimension, Adsorption, Fen, and Wet Forest Swamp
