Deep mining faces technological and operational challenges that require intensive research focus to manage the risks associated with Greenfield projects. These risks are related to higher temperatures/stress compared to "normal" mining conditions. Among the strategies to counter the risk associated with mine production systems at depth is the greater control of variables and the introduction of new technologies. Ground-related problems will be a particular focus in deep mines, and will require the justification of design alternatives that optimize the overall risk profile of a mining system. The question of which measures are appropriate to be introduced for deep mining is posed at the feasibility stage, where irreversible decisions in terms of infrastructure, method and technology needs are being made. The proposed work evaluates the interaction of quality and flexibility assessment in the planning and design of underground mines with ground-problem delays being the risk impediment to the production system. Quality measures can be introduced to enhance the performance of mine operations through statistical analyses that require cost and uncertainty data in a process capability/performance simulation analysis. Flexibility assessment through the application of real options and process simulation can provide the justification of alternatives that improve the robustness of a production system to meet its targets and the optimization of a system. The methodology in this research project includes the application of statistical methods and real options analysis to process simulation modelling, through case study work where ground-problem delays and the potential alternative to ameliorate their impact are considered. Quality enhancement and introduction of flexibility will have important capital and operating cost implications in the design of deep mining systems with the justification of alternatives being a function of the frequency and the impact of ground problems. The result will provide a vehicle for the evaluation of alternatives containing both flexibility and quality components.

深部采矿面临技术和业务挑战，需要集中研究，以管理与绿地项目相关的风险。与“正常”采矿条件相比，这些风险与较高的温度/应力有关。应对与深井采矿生产系统有关的风险的战略包括加强对变量的控制和采用新技术。与地面有关的问题将是深井采矿的一个特别重点，并将需要证明设计备选方案的合理性，以优化采矿系统的总体风险概况。在可行性阶段提出了对深部采矿采取哪些措施是适当的问题，在这个阶段，在基础设施、方法和技术需求方面做出了不可逆转的决定。拟议的工作评估了地下矿山规划和设计中的质量和灵活性评估之间的相互作用，而地面问题延误是生产系统的风险障碍。可以采用质量措施，通过在过程能力/性能模拟分析中需要成本和不确定性数据的统计分析来提高矿山作业的绩效。通过应用实物期权和过程模拟进行灵活性评估，可以为改进生产系统的稳健性以实现其目标和优化系统的备选方案提供理由。本研究项目的方法包括将统计方法和实物期权分析应用于过程模拟建模，通过案例研究工作，其中考虑了地面问题延迟及其改善其影响的潜在替代方案。质量的提高和灵活性的引入将对深部采矿系统的设计产生重要的资本和运营成本影响，因为备选方案的合理性取决于地面问题的频率和影响。结果将为评价同时包含灵活性和质量因素的替代方案提供一个工具。
