An Advanced Numerical Technique for Stability Analysis of Mining Excavations in Jointed/Faulted Rock Masses under High Stresses

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。这一发展涉及到一种新的求解方法，该方法是在有限元、边界元和带偏微分方程约束的大规模优化工作的基础上进行的。这项工作对澳大利亚采矿业极其重要，因为该项目的成果将为工程师提供一种创新的模拟技术，以优化矿山设计并预测和控制岩石破坏，从而减少矿场的人员伤亡和死亡人数。

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.
