Abstract:
Acid mine water bodies are one of the severe environmental problems in many mines including coal mines all over
the world. This problem is also found in a few coal and metal mines of India. In coal mines, the main cause of
acidity is the occurrence of pyrite and other sulfide metals in the form of a vein, granular and crystallized form in
coal and shale.
In this paper, a case study of the utilization of Flyashand overburden for neutralization of acidic water of coal mine
has been discussed. Theoretical and acid neutralization potentials of Flyashand O/B were determined. The acid
neutralization potential of Flyashand O/B for acid water treatment has been tested in the laboratory by using
Flyashand waste rock materials and acidic water of field. The results are encouraging and Flyashmay prove as a
good acid neutralizer with coal overburden material.
