Oil sand reaction to cable shovel motion

CIM Vancouver 2002
Tim Joseph,
Abstract This paper takes a look at the duty cycle of the P&H 4100 TS cable shovel and compares the dead weight and face activity loading of the dipper and track pads to the passive seismic response felt by the underfoot oil sand material.

It is known that the cyclic activity causes the stiffness of the underfoot material to deteriorate and provide a less than ideal footing for such a large piece of machinery. Consequences are manifest in the form of carbody and side frame cracks, increasing downtime, maintenance activity and cost, and loss of availability.

The objective of this work, as part of the Oil sands Equipment Interaction Program (OsEIP); currently a joint venture between JPi Ltd., Syncrude Canada Ltd., Caterpillar, P&H and the University of Alberta; is to identify and provide feedback to the manufacturer and end user a means of determining adverse oil sand – equipment interaction conditions in a predictive manner. This enables the manufacturer to incorporate this knowledge into the design process and the user to direct operations in a greater proactive rather than reactive stance.
