The Potential for Beneficial Reuse of Coal Fly Ash in Southwest Virginia Mining Environments

 

The purpose of this bulletin is to provide an overview of coal fly ash and its beneficial reuse potential in Appalachian coal mining environments. To do this, we first review how coal fly ash is generated and its physical and chemical properties from an Appalachian perspective. Next, a detailed summary of our Powell River Project research program is presented providing examples of regional fly ash properties and beneficial utilization potentials and limitations. The term beneficial reuse refers to the environmentally safe use of coal fly ash for purposes such as prevention of acid mine drainage or improvement of mine soil properties for revegetation. From our perspective, this term does not apply to the simple co-disposal of fly ash in mine fills, regardless of the relative safety of such practices.
