This study aimed to conduct geochemical analysis of overburden and interburden rocks in the coal mining area of PT. International Prima Coal, specifically Eagle 2, to prevent the production of acidic mine water caused by sulfide, such as pyrite. Net Acid Generation (NAG) analysis was used to classify the materials as PAF, NAF, or PAF-LC. A total of 17 samples were collected from SPC and PIT D locations using the Grab Sampling method. The laboratory analysis results showed that NAF material dominated the SPC location, while PAF material dominated the PIT D location. The implication of this study is that it can serve as a basis for future efforts to manage and mitigate the negative environmental impact of coal mining activities, especially in preventing the production of acidic mine water.
