Three critical factors affect equipment availability: . This manual is a guideline created to assist mining equipment ...
Influencing equipment performance through maintenance metrics ... and control the performance and availability of their equipment," say Abelardo Flores and Jim McCaherty, coauthors of "Performance Metrics for Mobile Mining Equipment," a guideline created to assist mining equipment users in the definition and use of uniform ...
The degree to which a system, subsystem or equipment is in a specified operable and committable state at the start of a mission, when the mission is called for at an unknown, a random, time. Simply put, availability is the proportion of time a system is in a functioning condition. This is often described as a mission capable rate.

What is Equipment Reliability and How Do You Get It? By Mike Sondalini and Howard Witt Abstract High equipment reliability is a choice and not an accident of fortune. To a great extent you can choose how long you want between equipment failures. You can deliver high equipment reliability
Operational Analysis of Mining Equipment in Opencast Mine using Overall Equipment Effectiveness (OEE) ... The original definition for OEE made use of Availability, Performance and Quality factor. Since it is ... availability, performance and utilization of these two equipment''s. The idle time Hours spent are needed to be
OEE for mining equipment OEE applications in mining industry differ from manufacturing industry. Therefore, it is necessary to develop equipment''s own classification framework for the losses, which should be associated with the components of availability, performance and quality [16]. The necessary data classification

STUDIES ON AVAILABILITY AND UTILISATION OF MINING EQUIPMENT AN OVERVIEW Arputharaj Deputy Chief Engineer / Mining, Neyveli Lignite Corporation Ltd, Tamilnadu, India ABSTRACT In any opencast mining project, the major share of initial capital investment goes towards the excavation and transportation equipment.
The equipment selection process for an underground mine design plan has an extremely wide scope as there are a myriad of parameters to consider when incorporating mobile and stationary equipment in hard or soft rock mining applications. This article primarily focuses on the initial selection of mobile equipment in hard rock mining operations.
Heavy Mobile Equipment Benchmark for Surface Mines (HME Benchmark) HME Benchmark allows users to select a machine and define its operating circumstances, generating a contextual estimate that details periodic maintenance costs, manpower requirements and machine availability .
Improving Availability Is Much More Than Maintenance. By R. Keith Mobley, Life Cycle Engineering Many confuse availability with equipment reliability. In reality, it is only one part of the calculation. Availability is the actual time that the machine or system is capable of production as a percent of total planned production time.
Availability, reliability, maintainability, and capability are components of the effectiveness equation. The effectiveness equation is a figure of merit which is helpful for deciding which component(s) detract from performance measures. In many continuous process plants the reliability component is the largest detractor from better performance.
Measuring Reliability. ... actually have a much greater influence on equipment condition and therefore they also must be held accountable for that equipment''s reliable performance. The fact is that in actual practice when operations and maintenance are jointly responsible for equipment reliability the opportunity to improve is significantly ...
OEE = Availability × Performance × Quality. The nature of this calculation makes achieving a high OEE score quite challenging. For example, if all three factors are 90%, the resultant OEE will only be 73%. In practice, the generally accepted worldclass goals for each factor are quite different from each other, as is shown in the image below.
• Supply cycle time performance • Maint, planning scheduling performance • Availability of skilled workforce • Equipment design usage • Effective Preventive/Predictive Maintenance • Equipment ownership and operator care • Rootcause and reliability analysis • Availability of skilled workforce • Balance of maintenance tactics
Performance measurement is a fundamental principle of management. The measurement of performance is important because it identifies current performance gaps between current and desired performance and provides indication of progress towards closing the gaps. Carefully selected key performance indicators identify precisely
OEE (Overall Equipment Effectiveness) is a "best practices" metric that identifies the percentage of planned production time that is truly productive. An OEE score of represents perfect production: manufacturing only good parts, as fast as possible, with no downtime. OEE is useful as both a benchmark and a baseline:

Note: ...
Monitoring of realtime performance versus plan. One benefit of realtime data is knowing the state and location of every piece of equipment in a mining operation at every second—and, in particular, whether it is operating according to or outside of the plan.
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.
Overall equipment effectiveness (OEE) is a measure of how well a manufacturing operation is utilized (facilities, time and material) compared to its full potential, during the periods when it is scheduled to run. it identifies the percentage of manufacturing time that is truly productive. An OEE of means that only good parts are produced ( quality), at the maximum speed ( ...
