Mining companies worldwide largely lost sight of productivity goals that had underpinned operating discipline in the lean years of the 1980s and 1990s, when parts of the industry had set a healthy record in productivity improvement (Exhibit 1). As the demand boom gathered pace, cost increases related to expanding production got badly out of ...
And, it makes it easy to track improvements in that process over time. What your OEE score doesn''t provide is any insights as to the underlying causes of lost productivity. This is the role of Availability, Performance, and Quality. In the preferred calculation you get the best of both worlds.
"Applying data mining to manufacturing: the nature and implications" provides a perspective on the possible use of data mining to improve equipment maintenance procedures. Data mining involves the process of going though large amounts of data using preprogrammed logic looking for both high level and low level trends.
Equipment Availability. Definition: "Equipment Utilization" measures the percentage of time a piece of equipment is actually operationally in a 24 hour day, for a given period of performance measurement is the productive time expressed as a percentage of the total time available. Responsibility: The reporting of Equipment Utilization is the responsibility of the Production Controller.

Only where a group of mines operates in a single district are costs comparable and then only with reservations. In general, cost systems are fairly uniform, yet in studying costs of a number of plants it is noticeable that in some cases there is a tendency to omit certain operations which are proper charges against ore dressing and treatment.
