Seige of Acre:Kempton Mine Complex, Kempton, Maryland. Final Report
The Seige of Acre Project is a field scale experiment to determine the degree to which acid production is reduced by covering the sub-aerial mine pavement and related mine debris with a hydraulically placed grout compounded from mine water and locally available power plant coal combustion products. The experimental site consists of three 16-foot wide mine tunnels, which are interconnected by several crosscuts developed in the normal manner of up dip room and pillar mining. The three tunnels extend 750 feet up a hill (and up dip) above the mine pool with overburden varying from 175 feet near the edge of the mine pool to 140 feet near the high wall where a surface mine cut into the underground works.
