Deep mine hydrogeology after closure: insights from the UK
as well as in several wellpreserved examples of modern deep coal mines. However, less attractive legacies of millennia of deep mining have become all too ap parent as most major UK coalfields (and all but a few mines working for industrial minerals and metals) have finally closed over the last decade. Once mines are abandoned and dewatering systems are withdrawn, the workings flood, in many ...Get Price

coal, closure, groundwater, hydrogeology, mine, prediction . 2 . 1. Introduction Why predict postclosure hydrogeology of coalfields? Deep mining of coal almost always extends below the water table and as such entails disruption of natural hydrogeological conditions. For the miner, the main consequence of this is a requirement for sustained mine dewatering throughout the life of the mine ...Get Price
