Abstract: Cable shovel excavators are used for primary production of geomaterials in many surface mining operations. A major problem in excavation is the variability of material diggability, resulting in varying mechanical energy ...

Abstract: Overburden excavation is an integral component of the surface mine production chain. In large mines, the walking dragline is a dominant strip mining machine. Dragline performance depends on the operating speed, the bucket ...

Abstract: Production cost and efficiency optimization for the Athabasca oil sands is a key to securing North America’s energy supply. Current oil sands production cost is about $13/bbl compared with ...

Abstract: The hydraulic shovel excavator has found significant applications in surface mining, construction, and geotechnical operations due to its flexibility and mobility. The key to high availability and utilization of this shovel ...

Abstract: Crude oil and gas are strategic commodities for U.S. national energy security. The demand for fossil fuel energy will continue to grow amid dwindling global supply. Other energy sources, such as oil sands and heavy oil ...

Abstract: In order to optimize the hydraulic transportation system efficiency and cost in the surface extraction of Athabasca oil sand deposits in Canada, there is a desire to extend the hydraulic transport system to production faces ...

Abstract: The study focuses on evaluating the factors contributing to the success of external stakeholder management (SM) at the project planning stage from the perspective of developing countries. Questionnaire survey data was ...
