Gold Mine

East Africa

This project comprised the geotechnical and geochemical classification of mining wastes and the long-term erosion assessment of several large waste rock dumps and tailings storage facilities.

The erosion assessment calibrated current, eroded surfaces to numerical models. The models (WEPP and SIBERIA) were then used to derive improved closure embankment profiles and provide design material grading to improve performance. Water management designs were crafted from the assessment of these landforms, which cover over 1000 ha of completed and operational areas.
