The aim of this project is to develop a sophisticated mathematical model and computational technique for the stability analysis of mining excavations in jointed/faulted rock masses. The development involves a novel solution method based on current work in finite element method, boundary element method and large-scale optimisation with partial differential equation constraints. The work is extremely important to the mining industry in Australia, as the outcomes of the project will provide engineers with an innovative simulation technique to optimise mine design and to predict and control rock failure so as to reduce personnel injuries and death toll in mine sites.

该项目的目的是开发一种复杂的数学模型和计算技术，用于节理/断层岩体中采矿开挖的稳定性分析。发展涉及到一种新的解决方法，目前的工作的基础上，有限元法，边界元法和大规模优化偏微分方程的约束。这项工作对澳大利亚的采矿业非常重要，因为该项目的成果将为工程师提供创新的模拟技术，以优化矿山设计，预测和控制岩石破坏，从而减少矿山的人员伤亡。
