Oil sand cyclic load - deformation behaviour below surface mining equipment

在阿萨巴斯卡油砂中运行超一流的采矿设备已被证明比作为最终用户的采矿公司预期的成本更高。 由于这些装置的周期性运动，对迅速恶化的油砂操作表面的维护随着机器尺寸的增加而升级。 相反，由于地面轮廓迅速恶化，对这些工具的结构部件的损坏也是昂贵的。 由于滚动阻力的增加以及油砂硬度的恶化，燃料使用和排放的增加继续产生环境问题。 全身振动（WBV）引起的背部问题更容易导致操作员受伤，这是由于不良操作表面条件导致的不良设备运动。 原始设备制造商（OEM）和油砂矿运营商认识到，缺乏对油砂表面操作条件的了解是所有上述问题的主要根源。

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.
