Title Injection of Fluidized Bed Combustion Ash into Mine Workings for Treatment of Acid Mine Drainage Type Journal Article
Year 2006 Publication Mine Water Env. Abbreviated Journal
Volume 25 Issue 1 Pages 45-55
Keywords acid mine drainage AMD alkaline injection technology fluidized bed combustion ash Oklahoma
Abstract A demonstration project was conducted to investigate treating acid mine water by alkaline injection technology (AIT). A total of 379 t of alkaline coal combustion byproduct was injected into in an eastern Oklahoma drift coal mine. AIT increased the pH and alkalinity, and reduced acidity and metal loading. Although large improvements in water quality were only observed for 15 months before the effluent water chemistry appeared to approach pre-injection conditions, a review of the data four years after injection identified statistically significant changes in the mine discharge compared to pre-injection conditions. Decreases in acidity (23%), iron (18%), and aluminium (47%) were observed, while an increase in pH (0.35 units) was noted. Presumably, the mine environment reached quasi-equilibrium with the alkalinity introduced to the system.

Title Mine drainage treatment in Polish lignite mining Type Journal Article
Year 1992 Publication Mine Water Env. Abbreviated Journal
Volume 11 Issue 1 Pages 35-44
Keywords laboratory scale tests plants bogs biological filters open cut mining mine drainage filtration flocculation radiation particle size suspended solids water treatment water discharge field tests lignite mines poland mining and industrial water water treatment water quality
Abstract The paper presents volumes and characteristics of water discharged from some Polish lignite open pit mines and discusses methods for its treatment. Results of research work concerned with increase in mine drainage efficiency by using processes of radiation, flocculation and filtration through a set of bog plants, iknown as grass filter are also discussed

Title Software Update to Better Predict Costs of Treating Mine Drainage Type Journal Article
Year 2005 Publication Mine Water Env. Abbreviated Journal
Volume 24 Issue 4 Pages 213-215
Keywords AMD prediction software
Abstract The U.S. Office of Surface Mining (OSM) is updating a popular software program that helps government agencies and mine water practioners predict what it will cost to treat acid mine drainage (AMD). Developers expect to release the update, AMDTreat Version 4.0, before the end of 2005. The new version will offer additional tools, expanded features, and a better user interface.

Title The Control of Acid Mine Drainage with Wetlands Type Journal Article
Year 1992 Publication Mine Water Env. Abbreviated Journal
Volume 11 Issue 3 Pages 27-34
Keywords acid mine drainage construction chemistry artificial wetlands pollution control performance evaluation coal mines pollution control and prevention
Abstract The recent increases in environmental legislation, especially in the USA'have meant that there is a need on behalf of the mining companies for more judicious operational planning and more thorough restoration techniques in order to reduce costs and prevent violation of the smctly enforced regulations. Water pollution is probably the greatest problem and many less enlightened operators, especially for example, in surface coal milling in Pennsylvania, have been forced into liquidation after having been unable to meet the severe restrictions on Acid Mine Drainage (AMD). The problems of AMD are also inherent in most forms of metalliferous and coal mining and also in some types of aggregate quarrying. As excavations go deeper in search of ever diminishing reserves then they are more likely to encounter groundwater which can become polluted if insufficient care is not taken. It is to be expected that the laws will also become more severe than they are at present in Europe and methods of treatment of AMD will need to be developed that are more efficient than the costly chemical methods currently used. Research by the author and others into the source of AMD pollution and its treatment with engineered wetlands and other operational methods are discussed in the paper. The methods have- the distinct benefit that they are cheap to install, are cost effective over a long period with the minimum of supervision and are environmentally acceptable to the planning and regulatory authorities.
