Utilization of Fly Ash and Coal Mine Refuse as a Road Base
In the coal mine refuse-fly ash system, the purpose of the fly ash was l) to fill the voids and thereby reduce the permeability of the system and 2) to neutralize acidity production from the pyritic refuse material. In the coal mine refuse-fly ash-lime system, the lime was added l) to promote pozzolanic or other cementing action that would occur in the fly ash and, 2) to provide an additional buffer for 5C1.

ash in opencast coal mine at Raigarh, India. Fly ash generated from the coal based thermal power plant is of great concern due to its disposal. Therefore proper utilization of the fly ash is highly demanded. It is observed that two types of dumps with alternative layer of only fly ash and overburden material, and overburden mixed with fly ash (25%) are found to be stable with safety factor more than 1.2.
