| Abstract |
Passive-treatment systems that mitigate acid-rock drainage from coal mines have been operating since the mid-1980s. Large systems at metal mines are being contemplated. A typical man-made passive-treatment-system can mimic a natural wetland by employing the same geochemical principles. Passive-treatment systems, however, are engineered to optimize the biogeochemical processes occurring in a natural wetland ecosystem. The passive-treatment methodology holds promise over chemical neutralization because large volumes of sludge are not generated. Metals may be precipitated as oxides, sulfides or carbonates in the passive-treatment system substrate. The key goal of a passive-treatment system is the long-term immobilization of metals in the substrate materials. The passive-treatment technique may not be applicable in all mine-drainage situations. -from Author |

| Abstract |
Das Grundprinzip der Vermeidung einer Säuregenerierung als Quelle für die Freisetzung saurer Grubenwässer ist die Isolation reaktionsfähiger Lagerstättenbestandteile durch Einkapselung, Abdeckung oder Oberflächenversiegelung. Die Hauptzielstellung besteht in der Unterbindung des freien Zutritts von Sauerstoff oder Wasser zu dem reaktionsfähigen Material. Es werden sehr verschiedenartige technologische Möglichkeiten zur Erreichung dieser Zielstellung vorgestellt und bewertet, die eine Präventivfunktion erfüllen und sich daher besonders für neue Aufhaldungen oder Tailingbecken anbieten. Dabei spielt bei der Auswahl des richtigen Verfahrens der Standort eine wichtige Rolle. Es werden auch Vorschläge zur Sanierung alter Halden und Absetzbecken unterbreitet, die vornehmlich auf die Schaffung effektiver Abdeckungen und die Realisierung von Kapselungsvarianten orientieren, aber auch Haldenumlagerungen sowie Wasseraufbereitungsmaßnahmen vorsehen. Es werden Probleme der Materialauswahl für die Abdeckungen zur Gewährleistung einer niedrigeren Permeabilität und einer hohen Langzeitstandsicherheit diskutiert und Fragen der Instandhaltung und des Monitorings behandelt. |
