Abstract

Systems models for the following four elements of mining design under water hazard are shown: underground inflow forecasting, economic optimal design and reliability analysis of minewater control works, and regional multiobjective planning. Deep mining in a karstic aquifer is considered where mining - aquifer interaction is modeled on a regional scale by a deterministic finite difference scheme, and on a local scale by a stochastic forecasting method. Bayesian analysis, simulation, failure tree method of reliability estimation, dynamic programing, multiobjective decision-making are the basic tools for model solution. It is believed that modeling principles as shown can be used for other mining engineering purposes.
