Abstract |
In der Regenzeit 1991/1992 wurden überraschend im Bereich des australischen Goldbergwerks Pine Creek saure Grubenwässer festgestellt, die eine ernsthafte Umweltgefährdung und einen deutlichen Anstieg bei den Betriebskosten verursachten. Diese sauren Grubenwässer traten als Folge von Laugungserscheinungen in den Halden auf. Zur Verminderung der Reaktionsfähigkeit der sulfidischen Berge wurde beschlossen, die Halden mit mehreren Schichten inerten Materials geringer Permeabilität abzudecken. Diese Abdeckung wurde anschließend verdichtet und begrünt. Bei den späteren Abbauarbeiten wurde eine prophylaktische Minimierung der begünstigenden Reaktionsbedingungen vorgenommen. Es wurde eine Integration von Abbau und Sanierungsmaßnahmen realisiert, bei der offene Tagebauflächen mit Haldenbergen verfüllt wurden. Die haldengefüllten Tagebaurestlöcher wurden außerdem teilgeflutet, um den Sauerstoffzutritt zu minimieren. Aus den gewonnenen Erfahrungen wird die Schlußfolgerung gezogen, das AMD-Problem bereits in der Planungsphase zu berücksichtigen und umfassende Untersuchungen einzuleiten. Es sind nicht erst im Stadium der Sanierung, sondern bereits bei den Abbauaktivitäten geeignete Maßnahmen einzuleiten, um unangenehme Überraschungen durch saure Grubenwässer, die übrigens sehr teuer werden können, zu vermeiden. |

Abstract |
Responsible mining companies have done much to redress the environmental damage of earlier technologies and continue to do more. In the Sudbury Basin, one of the most important mining areas in the world, both Inco Limited and Falconbridge Limited, two of the largest nickel producers, have significantly decreased sulphur dioxide emissions in the last 40 years from substantially 100% to about 10% or less of the sulphur in the ore; decreased water effluents by recycling; treated effluents to comply with government regulations; revegetated mine rock and surface tailings deposits and rehabilitated landscapes in the surrounding communities. Inco and Falconbridge continue to develop improved means for environmentally sound handling of all wastes including recycling and to reclaim land at abandoned mine sites. They have developed and implemented environmental policies and codes of practice, not only to comply with regulations, but to anticipate them. The mining industry recognizes the need for regulation to protect human health and the environment. Existing regulations are based on a hazard assessment approach. A more realistic, pragmatic and cost-effective basis for regulation is risk management. This relates any documented effects to measured exposures and recognizes the need for exposure levels low enough that incidence of adverse health effects is as low as in the surrounding ecosystem. |
