Abstract:
The recent experience with the design and operation of very high waste rock dumps (WRD) is discussed with
special emphasis on the determination of the geotechnical characteristics of waste rock subject to high
confining pressures and eventually also subject to in situ leaching. The results of drained and undrained
triaxial tests on samples of waste rock, carried out on a recently built apparatus capable of accepting
samples of 1 m in diameter and up to 203.2 mm size and confining pressures up to 3 MPa are commented on.
The use of these results in the analysis of possible static liquefaction is also discussed as well as the design
approach to consider earthquake effect and final closure of the facilities.
