The economics of today's mining industry is such that the major mining companies are increasing the use of massive mining methods. It is a step-change for the industry, from the traditional open-pit to a move underground. Therefore, continuous research must push the limits of promising technologies by innovation remains the forefront of research in this area. Among the underground mining methods available, caving methods are favored because of their low cost and high production rates. Block-cave mining is one of the best solutions for continuing the operation after shutting down the mine in deep open-pit mines; however, the production rate can drastically decrease due to adverse operational setbacks affecting revenue, time, and cost. A block cave mining operation constitutes challenges to meet operational production scheduling targets. The optimistic long-term and medium-term plans along with uncertainty and the synergistic effect of the failures in operational levels, cause a significant deviation from production plan targets. On the other hand, the substantial increase in data availability and high-computing power, and innovations in real-time monitoring systems enable the technological transformation of the mining industry. The proposed research aligns with the initiative's objective to avoid project disruptions and create feasible and reliable mine development plans to attract investment. The proposed research program builds on our past research and findings on long-term block-cave mine planning to develop an integrated framework that can produce feasible, reliable, and achievable block-cave mine plans to avoid project disruptions; improve operational efficiencies to generate maximum economic returns; and operate within acceptable social, legal, and regulatory constraints. We will establish alignment between long-term mine plans and short-term production scheduling in block caving so that the strategic objectives of the mining operation can be realized as planned. The overall objective is to link the optimal strategic mine plans to short-term production schedules and to honor all the technical mining constraints. This research directly contributes to creating new knowledge and innovative technologies for block-cave short-term production planning. This research focuses on applications of operations research, simulation, and data-driven approaches in underground mine short-term planning. It is anticipated that this research will contribute to responsible resource development by transferring knowledge to practitioners and end-users through prototype open-source software applications in the resources industry. Also, this research will contribute to training highly qualified mining professionals for research and practice in Canada and will provide a means to enhance resource economic performance and product supply.

当今采矿业的经济状况使得主要采矿公司正在增加大规模采矿方法的使用。从传统的露天开采转向地下开采，这是该行业的一次重大转变。因此，持续的研究必须通过创新来突破有前途的技术的极限，这仍然是该领域研究的前沿。在可用的地下采矿方法中，崩落法因其成本低、生产率高而受到青睐。分块洞采矿是深部露天矿山停矿后继续作业的最佳解决方案之一；然而，由于影响收入、时间和成本的不利运营挫折，生产率可能会急剧下降。块洞采矿作业对满足作业生产调度目标构成了挑战。乐观的中长期计划以及不确定性和运营水平失败的协同效应，导致生产计划目标出现重大偏差。另一方面，数据可用性和高算力的大幅提升，以及实时监控系统的创新，使得采矿业的技术变革成为可能。 拟议的研究符合该计划的目标，即避免项目中断并制定可行且可靠的矿山开发计划以吸引投资。拟议的研究计划以我们过去关于长期块洞采矿规划的研究和发现为基础，开发一个综合框架，可以制定可行、可靠和可实现的块洞采矿计划，以避免项目中断；提高运营效率以产生最大的经济回报；并在可接受的社会、法律和监管限制范围内运作。我们将把崩落崩落法的长期采矿计划与短期生产计划结合起来，使采矿作业的战略目标能够按计划实现。总体目标是将最佳战略采矿计划与短期生产计划联系起来，并满足所有技术采矿限制。这项研究直接有助于为块洞短期生产规划创造新知识和创新技术。本研究重点关注运筹学、模拟和数据驱动方法在地下矿山短期规划中的应用。预计这项研究将通过资源行业的原型开源软件应用程序将知识传递给从业者和最终用户，从而为负责任的资源开发做出贡献。此外，这项研究将有助于培训高素质采矿专业人员在加拿大进行研究和实践，并将提供提高资源经济绩效和产品供应的手段。
