The recent spate of catastrophic barricade failures in Australia and overseas resulting from poor mine drainage, has led to an immediate need for an increased understanding of the processes involved, and more accurate means by which the filling and drainage schedule of underground mines may be predicted (Kuganathan, 2001). A thorough investigation of the drainage characteristics of hydraulically backfilled mines has been undertaken at James Cook University (Townsville, Australia) through numerical modelling using the finite difference package FLAC, laboratory testing, scaled modelling, and in-situ instrumentation of a backfilled stopes. The development and verification of the three dimensional drainage program used to simulate a typical in-situ filling and drainage schedule, is described within the paper. This paper also discusses the application of this program to determine the effects of drain location and the distance the barricade is constructed from the stope on the discharge.
