摘要：

A numerical model for the hydraulic back-filling of two-dimensional mine stopes is presented. The use of the model is demonstrated by some analyses in which fill levels, water levels and the pore water pressures developed in the voids of the fill material are predicted. The effects on these features of various parameters, such as rate of pouring of the fill, the fill permeability and of drain location and performance, have been investigated. The model may be useful in the design and interpretation of experiments aimed at observing and measuring these phenomena. The model might be of some assistance in determining the general requirements for bulkheads and bulkhead drains and in the planning of filling operations.
