Hoist Help

Abstract:Two continuous improvement analysis tools, overall equipment analysis (OEE) and waterfall analysis, have been used successfully to enhance the performance of potash mine sites in Canada. This case study examines the use of these quality tools at the Mosaic Potash ULC in Saskatchewan to improve the performance of the mine's hoist operation. In underground mining, almost all improvements in the hoist operation — and upstream activities that increase the value of the total ore hoisting time — can reduce losses and contribute directly to the mine site's bottom line. The hoist — as the single piece of operating equipment working between upstream mining and downstream mineral refining processes — is in a unique position to reveal the location of a bottleneck in the value chain of the continuous refining …
