Abstract
Coal is a combustible fossil fuel, formed from plants that have been consolidated between rock strata and can be used by geothermal. World Energy Council said Indonesia is the fifth world coal producer after China, United States, India and Australia. Acid Mine Drainage is become one of environmental damage from coal massive exploitation in Indonesia. Precautions are required to reduce risks and minimize the formation of acid mine drainage at overburden disposal in order to meet the quality standards set by the Government. The action is carried out by isolating Potential Acid Forming (PAF) materials with non-acidic (NAF / Non Acid Forming) materials to avoid exposure to air and water with sulphide minerals. Good PAF and NAF material management in the disposal area will minimize the potential of acid mine drainage.

Summary
Mining0of minerals0and metals has become a major industry as one source of employment and economic improvement. While the rock NAF (Non Acid Forming) is a rock that does not have the potential to produce acid. Putra Perkasa Abadi Coal Mining Company has been operating in Site Girimulya since 2013 with a land area of ± 800 Ha, with a coal production target of 12 million tons of coal per year and 54 million BCM overburden.
