Water--a Hazard and a Nuisance.
Coal 1989 Oct; 26(8):60-63
To assure safety during operations, and to prevent water problems in future mining, barriers should be designed on conservative engineering guidelines, with an added safety factor based on anticipated hydrologic conditions. A careful analysis of barrier zones should be conducted in an effort to detect the presence of any geologic conditions that might lead to leakage or failure. Despite sound engineering and a large safety factor, serious leakage can develop as a result of unforeseen geologic conditions. Any water inflow in the vicinity of abandoned mines--whatever the water quality and whatever the indicated barrier width--should be considered a danger signal.
