Utilization of wet FGD material for AMD abatement in underground coal mines

摘要

Electric utility response to certain amendments of the Clean Air Act has resulted in a production of several types of alkaline coal combustion byproducts. Alkaline combustion byproducts are gaining increased usage for acid mine drainage mitigation and abatement as research leabs to a better understanding of their beneficial applications.Since January of 1997, Mettiki Coal Corporation has been injecting alkaline flue gas desulphurization byproducts from Vigrinia Electric's Mt. Storm Unit #3 wet limestone sctubber into abandoned portions of the active Mettiki mine. This paper provides an overview of the key design, transportation, regulatory, and environmental issues faced in the project.
