This project, in partnership with Objectivity Inc., a small software development company in the field of mining from Sudbury Canada, aims to develop and validate innovative optimization methodologies for the planning of the drilling exploration phase of mineral deposits. The software development team in Sudbury will collaborate with researchers in Polytechnique to develop, validate and integrate new planning algorithms into a graphical software application developed by Objectivity, which will allow geologists to evaluate various exploration scenarios. Specifically, this project first aims to compare a novel planning approach based on tridimensional optimization of drill-hole locations and spatial orientations with more traditional approaches based on two-dimensional planning based on sections. The project also aims to incorporate an uncertainty model of drill-hole trajectories into the formulation of the optimization problem. The third goal of the project is to improve the algorithmic efficiency of the optimization process through the development of specialized data-structures and algorithms, and their parallelization. This project will mobilize three graduate students and one part-time research professional from Polytechnique.

该项目与加拿大萨德伯里采矿领域的小型软件开发公司Objectivity Inc.合作，旨在开发和验证用于规划矿藏钻探勘探阶段的创新优化方法。萨德伯里的软件开发团队将与PolyTechnic的研究人员合作，开发、验证新的规划算法，并将其集成到由OBJECTY开发的图形软件应用程序中，这将使地质学家能够评估各种勘探方案。具体地说，本项目首先旨在比较基于钻孔位置和空间定向的三维优化的新规划方法与基于剖面的二维规划的更传统方法。该项目还旨在将钻孔轨迹的不确定性模型纳入优化问题的公式中。该项目的第三个目标是通过开发专门的数据结构和算法及其并行化来提高优化过程的算法效率。该项目将动员三名研究生和一名来自理工学院的兼职研究人员。
