GEOMINE STUDIO provides a full suite of technical services related to geochemistry and acid rock drainage (ARD) such as field investigations including site characterization, drilling, monitoring well installation, water quality sampling and monitoring, laboratory testing, interpretation and prediction as well as engineering and management for contaminant control. While assessment of waste dump stability involves well established geotechnical design methods, the real difficulty arises in assessing appropriate design shear strength parameters for the waste materials and dump foundations. The key issue is the shear strength of the waste material, which includes rock fragments of a tonne or more, and is therefore not amenable to normal laboratory testing. There is also the issue of the appropriate density to use for determi- ning design shear strengths. The procedure adopted involved the use of laboratory shear strengths of the fines component of the waste couple with back analysis of existing dump performance. Individual dump heights over 120m have been successfully operated.
