Abstract Details

The hydrology of abandoned, partially flooded coalmines is not well understood, including recharge mechanisms, preferential flow paths, and hydraulic connection among individual mines. The findings of this study will help in developing a sound remediation plan for the 2.6 cfs Corning AMD discharge, and will also provide insight into the behavior of other abandoned deep mine complexes that are partially above and below drainage. Within the Corning mine pool, the location of the partially flooded “beach” area extrapolated from head data in monitoring wells is on average 5 feet higher than the Corning discharge elevation and up to 2,200 ft in width and 16,000 ft in length. Subsidence recharge is significant contributing 12% during 2002 and over 50% during a large precipitation event. The mine pool exhibits seasonal or transient behavior with elevation changes greater than 5 ft during the study period, and the Corning discharge responds with seasonal fluctuations in flow and chemistry. The mine pool does not behave as a single hydrostatic pool according to hydraulic head data with varying degrees of confinement throughout the mine pool. A higher degree of confined aquifer behavior is displayed closer to the discharge point and unconfined (phreatic) behavior is present near the beach zone. Head data implies the existence of preferential flow paths within the mine pool and water quality data also indicates the mine pool is not well mixed with worse water quality in the eastern complex. A chemical gradient is apparent from west to east suggesting that mixing (i.e. dilution) is occurring between the west and east mines and a basic chemical [Cl−] mixing model determined that the eastern complex contributes nearly 50% of the Cl− load but only 10% of the flow.
