Relevance of sulphate reduction for model based prognosis of mine water quality development with reactive mass transport concepts

摘要

For adequate prognosis of mine water quality a reactive mass transport model has been used which allows for detailed process analysis including microbial catalysed reactions. It is obvious that bacteria activities influence mine water quality development and therefore affect water management and environmental impact. It could be shown that model results even with simplified approach give insight into process dynamics and interdependencies for sulphide formation and iron solid phases. However further studies on the microbial background are required for better model calibration and long term prognosis.
