Abstract
Research Characteristics of quality and porosity Coal Formation Tanjung, Barito Basin aims to determine the relationship among the permeability with coal quality . Sampling was conducted at PT Tanjung Alam Jaya in Tanjung Formation coal in seam A,B, C, and D by channel sampling. Proximate analysis, permeability and porosity were performed on the above samples. The problem in this research is how the relationship with coal porosity, permeability, and quality in Tanjung Formation middle coal rank on methane gas absorption. Based on the characteristics of the porosity in the coal seam A, B, C, and D have a porosity range of 2. 38 to 2.64 % while the permeability has a value of 0.52 - 0.62 mDarcy. Proximate analysis results on ash 2.56 - 23.16 %,adb, moisture 2.51 - 3.74 %, adb, carbon 35.91 -47.7 %, adb, and sulfur 0.32 - 0.44 %, adb. Methane gas absoprtion on seam A : 294 scf/t,seam B : 315 scf/t, seam C : 431 scf/t, and seam D : 425 scf/t. The relationship between ash content, carbon, and permiability to the absorption of methane gas has a regular graph, where the lower ash content , the greater of carbon, the greater of permiability will have a large absorption of methane Keyword : adsorption, Tanjung Formation, ash, methane gas, coal rank.
