The sustainable development and utilization of mineral resources and reserves ensures the continued supply of raw materials, metals and energy we rely upon. Sustainable development is a critical global problem, particularly given the fast growth and demand of emerging economies and increasing environmental concerns. Several sources of uncertainty impact sustainable mineral resource development: technical, financial, and environmental. Technical and economic uncertainties include the ability of orebodies to supply raw materials, operational mining uncertainties, fluctuating market demand for raw materials and related commodity prices. To date our ongoing research has shifted the paradigm for mine design and production scheduling (MDPS) through new technological advances founded on models of uncertainty (stochastic models) and optimization. These quantify uncertainty and manage risk, maximize productivity and mine life, and increase return on investment. During the past 5 years the new stochastic mine planning optimization framework has included several novel methods for risk-based MDPS, as well as modelling the spatial aspects of pertinent attributes of mineral deposits. Field testing shows that these methods can increase metal production for the same assets by about 15%, increase life of mine, and add about 25% of economic value compared to best conventional practices (differences are based on identical data and production characteristics). These improvements are only due to the new technologies being developed and contribute to the sustainable utilization of mineral resources and reserves through better financial performance, and technically defendable and objective decision-making. Based upon our research and learning to date, a new five year research program is proposed to explore and further develop the above new stochastic MDPS paradigm, through: new computationally efficient stochastic optimization methods, new high-order stochastic models, and risk-based financial models. This will include expanding the field of research, addressing new problems encountered in our past research, full-field testing of new methods, and increasing our understanding of the new stochastic framework and related technologies.

矿产资源和储量的可持续发展和利用可确保我们依靠的原材料，金属和能源的持续供应。 可持续发展是一个关键的全球问题，尤其是考虑到新兴经济体的快速增长和需求以及日益增长的环境问题。 不确定性的几种来源影响可持续的矿产资源开发：技术，财务和环境。技术和经济的不确定性包括Orebodies提供原材料的能力，运营采矿不确定性，对原材料的市场需求以及相关商品价格的波动。 迄今为止，我们正在进行的研究通过基于不确定性模型（随机模型）和优化建立的新技术进步改变了矿山设计和生产计划（MDP）的范式。这些量化不确定性并管理风险，最大化生产率和矿山寿命，并增加投资回报率。在过去的5年中，新的随机矿山计划优化框架包括几种基于风险的MDP的新方法，以及对矿物质矿床相关属性的空间方面进行建模。现场测试表明，与最佳常规实践相比，这些方法可以将同一资产的金属产量增加约15％，并增加了我的寿命，并增加了经济价值的25％（差异是基于相同的数据和生产特征）。这些改进仅是由于开发了新技术，并通过更好的财务绩效以及技术上可以捍卫和客观的决策来促进矿产资源和储量的可持续利用。 根据我们的研究和学习，提出了一项新的五年研究计划，以探索和进一步开发上述新的随机MDPS范式，通过以下方式：新的计算有效的随机随机优化方法，新的高阶随机模型和基于风险的财务模型。这将包括扩大研究领域，解决过去研究中遇到的新问题，对新方法的全场测试以及对新随机框架和相关技术的了解。
