摘要

A successful mine must strive to maintain a constant level of production. To achieve this, rock broken in the workplace must be removed to surface on a continuous basis, with minimal interruption. Ore pass systems play a critical role in this process, and the integrity of the ore pass excavations is crucial to maintaining production requirements. Over the life of the mine, ore pass integrity deteriorates. Ore passes are subjected to changing stress environments as a result of mining, to wear and abrasion due to the flow of broken ore, as well as to the effect of rockwall failures around and on geological discontinuities. The resulting deterioration may result in the ore pass no longer being fit for purpose, in which case remedial measures are required.
