Oil sand cyclic load - deformation behaviour below surface mining equipment

事实证明，在阿萨巴斯卡油砂中运营超大型采矿设备的成本高于矿业公司作为最终用户的预期。由于这些装置的循环运动，对迅速恶化的油砂工作面的维护随着机器尺寸的增加而升级。相反，由于地面轮廓的迅速恶化，对这些工具的结构部件的损坏也是代价高昂的。随着油砂硬度的恶化，滚动阻力增加，燃料使用量和排放量增加，继续引起环境问题。操作员受伤更多的是以全身振动(WBV)引起的背部问题为幌子，归因于设备在恶劣的操作表面条件下的不利运动。原始设备制造商(OEM)和油砂开采业务意识到，对油砂表面作业条件缺乏了解是上述所有问题的主要根源。

Operation of ultra class mining equipment in the Athabasca oil sands has proven more costly than anticipated by mining companies as end users. Maintenance of rapidly deteriorating oil sand operating surfaces, due to the cyclic motion of these units, has escalated with increase in size of machines. Conversely, damage to structural components of these tools, due to rapidly deteriorating ground profiles, is also costly. Increased fuel use and emissions, attributed to an increase in rolling resistance with deterioration in oil sand stiffness, continue to generate environmental concerns. Injury to operators is more frequent in the guise of whole body vibration (WBV) induced back issues, attributed to adverse equipment motions in response to poor operating surface conditions. Original equipment manufacturers (OEMs) and oil sand mine operations realize that a lack of understanding of the oil sand surface operating conditions is a dominant root cause of all of the above issues.
