INTRODUCTION
Mine waste rock piles, or rockwaste dumps, containing metallic sulphides are a favourable
environment for the generation of acid mine drainage (AMD). There are many physical,
geochemical and biological processes that lead to the production of AMD within waste rock
piles. One of the most critical of these is water flow and water distribution in the waste rock.
To fully understand this process, it is critical to know the internal structure of waste rock
piles. In this paper, the authors show the results of an investigation where resistivity and
ground penetrating radar (GPR) geophysical methods have been used to study mine dumps.
