Ash utilization for elimination of acid mine drainage
- Maryland Dept. of Natural Resources, Annapolis, MD (United States)
Maryland is surrounded by states whose coal production exceeds its own, namely West Virginia, Pennsylvania, and Virginia. Because of the State`s relatively limited coal production, the distribution of Abandoned Mine Land (AML) funds mandated by law leaves the State at a disadvantage. In order to support maryland`s overall ash utilization program, the State solicits assistance from electric utilities and any other parties who may benefit from the development of a cost-effective technology to seal abandoned underground mines with CCB-based grouts, replacing the conventional use of more costly Portland cement for such applications. The development of these mine sealing techniques can be used to abate Maryland`s AMD discharges, because sealing prevents the exposure of sulfur-bearing minerals in coal seams to oxygen and water, which causes AMD. Ultimately, it is for this reason that Maryland`s overall ash utilization program was developed: to coordinate and encourage the large-scale utilization of CCBs to eliminate AMD in Maryland waters.
