- Acid mine drainage (AAT) is the environmental impact arising from a process of coal mining operations. The formation affected by acid mine drainage and terhidrolisisnya oxidized pyrite content in the waste rock. The existence of this AAT negatively affecting the environment in which the lead increasing soil acidity, lowering the pH of the soil and water can corrode the mining process tool. In AAT prevention efforts done them with prevention and treatment. In the method of prevention can be done in an effort to avoid one of the AAT-forming factor is whether the process of oxidation or hydrolysis. The results of the sample characteristics can be stated that the 4 samples declared as rock acid-forming potential as to sample A, B, C and D and sample E as Uncertain. From the results of the study of the use of coal ash as material waste rock neutralizing potential sources of forming AAT then the result is that coal ash can prevent the formation of AAT. This test is done by layering and blending coal ash dumping ground further tested by flowing water into the material and can do analysis the results of leachate pH, content of metal (Fe, Mn and Al). The analysis results showed that the pH of the leachate in each test ranged 6-7, the metal content of Fe, Mn and SO4 respectively 1.8 -0.1, 6 – 1,2 dan 0.9 -0.1
