| Abstract |
Nach einer Beschreibung der Bergbauaktivitäen (Tief- und Tagebau) in der australischen Goldlagerstätte Pajingo wird detailliert auf die Bemühungen zur Gewährleistung des Umweltschutzes und vor allem auf die Minimierung der Freisetzung saurer Grubenwässer eingegangen. Die bei der Lösung der Aufgabenstellung zu beachtenden Besonderheiten resultieren aus der kurzen Lebensdauer der Grube, in der die 1987 begonnene Abbautätigkeit bereits im Jahr 1996 wieder beendet wurde. Aus diesem Grund wurden bereits im Planungsstadium und während der Abbautätigkeit vorbeugende Strategien zur Minimierung des AMD-Problems verwirklicht, die ausführlich beschrieben werden. Sulfidische Berge und Aufbereitungsrückstände wurden planmäßig so aufgehaldet oder eingelagert, daß sie stets von einer Schutzschicht aus oxidischem Material umgeben waren. Durch diese Einkapselung reaktionsfähiger sulfidischer Bestandteile sowie die Abdeckung der Tailings des Aufbereitungsprozesses gelang es, die Auswirkungen der Säuregenerierung zu minimieren. Es werden die betrieblichen Erfahrungen, die technologischen Besonderheiten und die Monitoringaktivitäten beschrieben. Es werden auch Angaben zum Kostenaufwand gemacht. |

| Abstract |
In the report, wetland technology is described in which the main reactive layer is limestone gravel (rather than organic material) which is overlain by a fine gravel filter and soil. The three-year project included laboratory and field studies. Vertical aerated wetlands, simulated by columns, constructed in the field and in the laboratory, were operated during the project. The report presents a summary of results given in previous reports and summaries of results obtained using water from Butte, MT, and field studies at the Rockford Tunnel, near Idaho Springs, CO. |

| Abstract |
Laboratory tests with synthetic acid mine water show the sealing effect of the gelatinous precipitate that forms when hydrated lime or powdered limestone is added in a simulated mine entry closed by a porous barrier.^Field tests were conducted in a recently abandoned coal mine.^Hydrated lime and limestone slurries were pumped into the mine water behind rubble barriers through 2-inch steel pipes to test the laboratory findings.^The outflow was observed at weirs attached to the ends of two 12-inch diameter drain pipes.^The results indicated that only temporary sealing of the outflow was achieved and that neutralization took place when the interior water flow conditions were favorable. |
