Acid Mine Drainage (AMD) attributed to mine operation is considered one of serious environmental problems in the world. Cover system is utilized as an environmentally-friendly and an effective way for prevention of AMD in many cases in open cast coal mines in Indonesia. Waste rocks are classified into Potentially Acid Forming (PAF) or Non Acid Forming (NAF) on the basis of geochemical properties of...
Acid Mine Drainage (AMD) is one of the environmental problems caused in mining operation. The exposure of sulfide minerals in rocks to water and oxygen in the excavation process leads to AMD. The cover system has been constructed to prevent AMD in many cases in Indonesia for the availability and low-cost maintenance. Waste rocks are classified into Potentially Acid Forming (PAF), which is sulfur-bearing...
