Abstract
Acid mine drainage (AMD) can be curbed by covering tailings with capillary barriers. The purposes of these barriers is to prevent O₂ from interacting with mine residues. This control can be made by keeping a high degree of moisture inside the cover material. Saturation is thus a key parameter to be monitored. The purpose of this paper is to present how the time domain reflectometry (TDR) technique can be used in order to monitor the volumetric water content (q) for pulp and paper residues that have been used as capillary barriers. Calibration curves for deinking residues are presented and compared to literature data relating to mineral and organic soils.
