Abstract
This research is conducted at coal mine, located on Barito Basin, South kalimantan, Indonesia. The purpose is to characterize geochemistry and mineralogy control of rocks for acid mine drainage prediction to prevent acid mine drainage formation. Rocks geochemical characterization of PAF (Potential acid Forming), NAF (Non Acid Forming), and uncertain material is obtained based on result of overbuden geochemical test comprise paste pH, NAG (Net Acid Generating), TS (Total Sulphur), ANC (Acid Neutralization Capacity), percentage of rocks mineral composition analyzed using XRD. The result of this reasearch shows material is classified into NAF material (81%) and PAF LC (Loc Capacity) material (5%); PAF MC (Medium Capacity) material (10%); PAF HC (High Capacity) material (1%); an uncertain data (3%). NAF material is dominated by mudstore. Based on the research material of neutralization is low and comprise of silica, plagioclase, and aluminosilicate mineral thus acid mine drainage formation shuold be prevented uses dry cover method with encapsulation.
