High resolution 3D optical coordinate measurement system for multiscale fractured rock mass characterization

所要求的3D光学测量系统将支持我们的研究工作，通过专门考虑岩石的断裂粗糙度和微观尺度特性，开发一种新的方法来模拟断裂岩体的流体力学行为。所要求的设备将专门用于实验室和现场尺度的高分辨率岩石表面粗糙度测量，以及现场的岩体结构测绘。所要求的设备将在实验室和现场无缝使用，它将允许以低至10微米的分辨率测量表面粗糙度。这种新方法将使我们的团队能够获得关于岩石结构和原位断裂粗糙度（采矿漂移规模）的相同信息，这些信息今天只能在实验室条件下获得。使用所要求的高分辨率3D光学测量系统将使我们能够“将实验室带入矿山”，并提供必要的约束来测试描述断裂岩体行为的数值和分析模型，其中复杂的表面粗糙度几何形状，非均质颗粒分布，空洞和缺陷的存在仍然很难模拟。预计提高对裂隙岩体水力力学行为的理解和预测所带来的技术和经济效益将对采矿业（即快速漂移）和环境管理政策（即安大略省环境部法案）产生长期影响。所要求的系统支持的研究计划为实验和数值岩石力学方面的高素质人员培训提供了独特的机会，并将加强加拿大的矿产工业。

The requested 3D optical measurement system will support our research effort toward the development of a novel approach for modeling the hydro-mechanical behaviour of fractured rock masses by specifically accounting for fracture roughness and microscale properties of the rock. The requested equipment will be dedicated to high-resolution rock surface roughness measurement at the laboratory and field scale, and rock mass structure mapping in the field.      The requested equipment will be used seamlessly in the laboratory and in the field and it will allow surface roughness to be measured at a resolution down to 10 microns. This new approach will enable our groups to acquire the same information regarding rock structure and fracture roughness in situ (mining drift scale) that today are possible only under laboratory conditions.      Using the requested high-resolution 3D optical measurement system will allow us to "bring the laboratory in the mine" and to provide the necessary constraints to test numerical and analytical models for describing fractured rock mass behavior, where complex surface roughness geometry, heterogeneous grain distribution, presence of voids and flaws remain very difficult to simulate.      It is expected that the technical and economic benefit of improved understanding and predicting fractured rock mass hydro-mechanical behavior will have long term impact on the mining industry (i.e., rapid drifting) and environmental management policies (i.e., Ontario Ministry of the Environment Acts).      The research program supported by the requested system offers a unique opportunity for highly qualified personnel training in experimental and numerical rock mechanics, and it will strengthen the Canadian mineral industry.
