Abstract
A fill material mix that includes coal processing wastes, at least one coal combustion by-product and a neutralizing/stabilizing by-product that may be the same as or different than the coal combustion by-product is mixed with water to form a mortar. The mortar can be placed in abandoned mines and other appropriate underground or surface locations as a fill material that is environmentally more benign that the individual components of the mix. The mortar cures rapidly to provide a surface that can support heavy equipment.
