Holistic Design of Wetlands for Mine Water Treatment and Biodiversity: A Case StudyInternational journal of mine water - Tập 41 - Trang 292-299 - 2022
André Sobolewski, Noah Sobolewski
Passive treatment wetlands are conventionally designed with the primary objective of purifying contaminated mine water; any benefit of enhanced biodiversity is ancillary. We propose a new approach that incorporates enhanced biodiversity as an explicit objective. In this approach, treatment units are selected based on water flows and chemistry and the ecological requirements of key species are iden...... hiện toàn bộ
Natural Radioactivity in Polish Coal Mines: An Attempt to Assess the Trend of Radium Release into the EnvironmentInternational journal of mine water - Tập 38 - Trang 581-589 - 2019

The highly mineralised formation waters in the coal mines of Poland’s Upper Silesian Coal Basin contain natural radioactive nuclides, mostly radium. The 226Ra concentration in the groundwater that flows into the underground mine workings reaches 390 Bq/L, and is sometimes exceeded by the 228Ra concentration. The radium-bearing water sometimes also contain barium ions, which enables coprecipitation...... hiện toàn bộ
The Influence of Large Scale Phosphate Mining on the Water Quality of the Huangbaihe River Basin in China: Dominant Pollutants and Spatial DistributionsInternational journal of mine water - Tập 38 - Trang 366-377 - 2019

Large scale phosphate mining in the Huangbaihe River Basin, China has reduced the self-purification capacity of the basin’s fresh water. Three years (2014–2016) of monitoring data and chemometric analysis were used to identify the dominant pollutants and define their spatial distribution in the basin. Principal component analysis was applied to determine the contribution of the individual pollutan...... hiện toàn bộ
Storage of water in the voids of abandoned mines and in fractured rocksInternational journal of mine water - Tập 14 - Trang 57-70 - 1995
O. Sammarco
This paper describes the characteristics that abandoned mines and fractured igneous and metamorphic rocks must have before they can be utilized as water reservoirs. The geometries of the networks produced by the interconnections of the fractures in rock are frequently irregular and unknown and the experimental results reported indicate that the flow of ground water through these fractures is equal...... hiện toàn bộ
Distribution of water in deep gold mines in South AfricaInternational journal of mine water - Tập 2 - Trang 21-30 - 1983
D Stephenson
Gold mines in South Africa use large volumes of water for cooling and other purposes underground. The mines are often at great depths, for example 3600 metres below surface level. Water piped down the shaft can therefore be at high pressures unless a system of pressure reducing dams or valves is installed. Modern practice is to utilize the high water pressures wherever possible. Examples of the us...... hiện toàn bộ
In-Lake Neutralization: Quantification and Prognoses of the Acid Load into a Conditioned Pit Lake (Lake Bockwitz, Central Germany)International journal of mine water - Tập 31 - Trang 320-338 - 2012
Kai-Uwe Ulrich, Christian Bethge, Ina Guderitz, Ben Heinrich, Volker Neumann, Claus Nitsche, Friedrich-Carl Benthaus
The formerly highly acidic pit Lake Bockwitz south of Leipzig (Germany) has been repeatedly treated since 2004 with soda ash to meet water quality criteria for the lake effluent. Intense monitoring of water quality parameters showed that previous predictions underestimated the acid load into the lake. Field research and lab experiments were designed to identify and quantify the processes responsib...... hiện toàn bộ
