Abstract

Current simple mine water filling models suffer from two drawbacks: (1) they often do not account for variations in mine void volume with depth; and (2) they assume that recharge to the mine is approximately constant. The Mine Water Filling Model (MIFIM) presented here rectifies these drawbacks by presenting the concept of effective area (Ea) in a lookup table and assigning deep ground water inflows a conductance whereby inflow varies in inverse proportion to mine water head, once the mine water level exceeds the level of the water inflow. The MIFIM concept may be readily programmed in a computer spreadsheet environment, with simple graphical output. The approach is particularly suited to mines in low permeability rock, with a limited number of discrete inflow features.
