Abstract:

Acid mine drainage (AMD) is one of negative impact resulted by mining operation which might
threated its environment. Therefore, Identifying AMD is very important to anticipate spreading of this
mining water’s production.
At Binuang area, South Kalimantan Province, coal mining produced waste dumps of AMD.
Understanding geological condition is very important to consider tasks in order to prohibit and treat
this disposal.
AMD at the research area is found in many settlement ponds, have 2.8 – 4.4 in pH, as
calcium-sulphate and calcium-magnesium sulphate types. The AMD accumulation in study area was
controlled by local geological condition, such as basin topography, weathering, sulfide minerals
accurence (pyrites dominantly) and geological structures as joints and minor faults, as well as climate
(rainfall and hot temperature).
Those are several methods to tackling AMD. The first method is active treatment for
neutralizing the acid water. The second method is passive treatment that usually done by introducing
artificial wetland. The last method is building encapsulation in-pit disposal.
