Sealing abandoned mines with treated flyash kills two birds with one stone
- Environmental Resources Management Inc. (United States)
Environmentally benign disposal of coal combustion products/by-products (CCPs) such as flyash and bottom ash has been a problem since the first coal-fired power plant went on-line. In recent years, ways have been developed to recycle CCPs into useful commercial products like bricks and roadbase. This article describes an innovative State of Maryland program that is putting CCPs to yet another use: stabilizing abandoned mines to permanently sequester acids and harmful metals. As engineering consultants to the State's Power Plant Research Project (PPRP), Environmental Resources Management (ERM) Inc. has conducted several projects to evaluate and demonstrate the beneficial use of CCPs for deep mine stabilization. These are several hundred abandoned underground mines in western Maryland and several thousand across the Mid-Atlantic Highlands and their proximity to coal-fired plants makes it cost-effective to transport CCPs via existing railroads and highways. 8 figs.
