Abstract
ABSTRACT A comprehensive laboratory testing program has been conducted to establish the engineering properties of gold tailings from Kidston Gold Mines in North Queensland, Australia. The engineering properties of the tailings have been categorised into textural, hydraulic, and mechanical properties. The textural properties include the particle size distribution and the specific gravity. The hydraulic properties include the water characteristic curve, and the saturated and unsaturated hydraulic conductivity. Various models that describe the tailings water characteristic curve and hydraulic conductivity function have been presented. The mechanical properties include the bulk modulus, Poisson's ratio, the friction angle, the dilation angle, and the unsaturated shear strength parameters. The engineering properties of the tailings are vital to the management of the tailings both during the mine's operation, and long after its de-commissioning.
