Abstract
This paper describes an investigation of water level fluctuation in five wells positioned over three consecutively mined longwall panels that was initiated in conjunction with an intensive subsidence monitoring program. The purpose of this work was to provide detailed information which could be used to predict certain hydrologic effects of longwall mining in the Northern Appalachian coal region. The results of this case study indicate that water level fluctuations in the local ground water system above longwall panels is associated with subsidence and that the static level will generally reestablish at or near the pre-mining elevation after mining is completed.
