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

所要求的三维光学测量系统将支持我们的研究工作，对开发一种新的方法来模拟断裂岩体的水力力学行为，特别是占断裂粗糙度和岩石的微观性质。所要求的设备将专门用于在实验室和现场进行高分辨率的岩石表面粗糙度测量，并在现场绘制岩体结构图。 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相同的信息，岩石结构和断裂粗糙度在现场（采矿巷道规模），今天是可能的，只有在实验室条件下。 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”，并提供必要的约束条件，以测试用于描述破碎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，不均匀的颗粒分布，空隙和缺陷的存在仍然非常难以模拟。 预期改进的理解和预测破裂岩体流体力学行为的技术和经济效益将对采矿业产生长期影响（即，快速漂移）和环境管理政策（即，安大略环境部法）。 由所要求的系统支持的研究计划为实验和数值岩石力学的高素质人才培训提供了一个独特的机会，它将加强加拿大矿业。

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.
