项目摘要

The proposed research will use advanced pressuremeter testing to determine the in-situ characteristics of the shale overburden and oil sands formations at an advancing oil sands mine. The characteristics of interest will be to develop non-linear stiffness models capable of capturing weakened, post-yield deformations. The research will also attempt to accurately determine the evolution of the principle stresses in-situ prior to mine excavation and after the completion of pit wall excavation. Finally, testing in the rich feed oil sands will attempt to characterize the strength loss of over-saturated soils (with respect to dissolved gas) during pit wall excavation. The parameters obtained from the advanced field program will be supplemented by laboratory tests and fed into 2-dimensional and 3-dimensional stress-strain models capable of predicting pit wall movements during mine advancement. The efficacy of these models will then be compared to field monitoring programs including physical monitoring and remote sensing techniques. The goal of this research is to better develop a displacement based observational design for pit wall construction through the Cretaceous clay shale and to better predict the mechanisms associated with gas dissolution and flow slides, which can occur in rich feed ore. These goals will be used by the Industrial Partner to provide information needed to manage risks associated with worker health and safety as well as potential production downtime.
拟议的研究将使用先进的压力计测试,以确定在推进油砂矿的页岩覆盖层和油砂地层的原位特性。感兴趣的特点将是开发非线性刚度模型,能够捕捉削弱,屈服后变形。研究还将试图准确地确定主应力在矿山开挖前和坑壁开挖完成后的演变。最后,在富进料油砂中进行的测试将试图表征坑壁开挖期间过饱和土壤(相对于溶解气体)的强度损失。从先进的现场程序中获得的参数将通过实验室测试进行补充,并输入能够预测矿井推进过程中坑壁移动的二维和三维应力应变模型。然后将这些模型的功效与包括物理监测和遥感技术在内的实地监测方案进行比较。本研究的目标是更好地开发一个位移为基础的观测设计坑壁建设通过白垩纪粘土页岩,并更好地预测机制与气体溶解和流动幻灯片,这可能会发生在丰富的饲料矿石。工业合作伙伴将使用这些目标来提供管理与工人健康和安全相关的风险以及潜在生产停机所需的信息。
