Slurry transportation is an economic haulage system in oil sands and coal mining operations characterized by long haulage distances and rugged terrain. In such conditions, the ton-km-hr limits are exceeded creating extreme tire wear and high maintenance costs. Steep haul grades and rugged terrain also cause mechanical wear and tear, which decrease haulage equipment economic life. Hydraulic transportation is a proven and viable technology for slurry transportation in such conditions and there is an increasing demand to extend the current hydraulic transport systems to transport oil sands slurry from the mining face. In this study, the authors develop the ground articulating pipeline (GAP) technology to address this problem. The GAP system will move on a soft oil sand terrain with large surface deflections for achieving production targets. The use of this technology introduces unique dynamic and bearing capacity problems of oil sand terrain. These problems require rigorous modeling, simulation and analysis to provide solutions and examine its viability potential. Toward this objective, mathematical models governing the interaction of the GAP system and the oil sand terrain have been modeled using the theory of multi-body and soil dynamics. These models consist of the GAP track-oil sand contact model for generating the contact forces between oil sands and track and load-deformation of oil sand model for capturing its dynamic behavior. A virtual prototype of the GAP dynamic behavior has been created and simulated in the Automatic Dynamic Analysis Mechanical Systems (ADAMS) software environment. The simulation result of the effect of load on oil sand deformation indicates that maximum deformation value increases non-linearly with load varying from 0 to 60t. This study provides a solid foundation for further research and the GAP technology development.
