The Geomechanics Group and the Mine-to-Mill Groups at the University of British Columbia are actively pursuing research on Cave-to-Mill, an innovative approach to integrating cave mining with milling processes to improve production forecasting and support real time grade control. Based on recent research efforts using preliminary information from the New Afton mine, the Cave-to-Mill approach can change the way that deep low-grade high tonnage deposits are mined in the future. The proposed research will advance cave mining by increasing project value and energy performance. The research is supported by the New Afton Mine as well as Canadian technology providers that are critical to the development of the Cave to Mill concept. The proposed research spans across fields that are particular to cave mining operations and looks to adopt operational strategies that up to now have been carried out at open-pit operations. The research will relate the underground caved ore size and hardness to the downstream mineral processing performance. Furthermore, it will investigate the use of sensor-based sorting systems at a cave operation. A two-year NSERC Collaborative Research and Development (CRD) grant is proposed that will work towards integrating sophisticated laboratory experiments and numerical methods to leverage historical data from the operation of the current East and West Caves to generate predictive models for evaluation, planning and potential development of new cave areas at New Afton (e.g. the C-Zone, that is being considered for development in the near future). The research will apply sensing systems to classify rock according to parameters such as particle size, hardness, metal content and ore type that will inform practices such as sorting, campaigning or blending to reduce energy consumption and benefit overall process metallurgy.

不列颠哥伦比亚省大学的地质力学小组和矿到磨小组正在积极开展对洞穴到磨的研究，这是一种将洞穴采矿与磨矿工艺相结合的创新方法，可改善产量预测并支持真实的时间品位控制。根据最近使用New Afton矿初步信息的研究工作，Cave-to-Mill方法可以改变未来开采深层低品位高吨位矿床的方式。拟议的研究将通过增加项目价值和能源绩效来促进洞穴采矿。该研究得到了新阿夫顿矿以及加拿大技术提供商的支持，这些技术提供商对洞穴到磨坊概念的发展至关重要。拟议的研究跨越了洞穴采矿作业特有的领域，并希望采用迄今为止在露天采矿作业中实施的运营策略。该研究将地下崩落矿石的粒度和硬度与下游选矿性能联系起来。此外，它将调查使用传感器为基础的分拣系统在洞穴操作。一项为期两年的NSERC合作研究与开发（CRD）拨款将致力于整合先进的实验室实验和数值方法，以利用当前东、西洞穴运营的历史数据，为评估、规划和新阿夫顿新洞穴区域的潜在开发（例如，正在考虑在不久的将来开发的C区）生成预测模型。该研究将应用传感系统根据粒度、硬度、金属含量和矿石类型等参数对岩石进行分类，这些参数将为分选、竞选或混合等实践提供信息，以降低能耗并使整个工艺冶金受益。
