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 = 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 world-class goals for each factor are quite different from each other, as is shown in the image below.
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
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.

STUDIES ON AVAILABILITY AND UTILISATION OF MINING EQUIPMENT- AN OVERVIEW M.E.Michael 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.
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:
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, i.e. 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.
Availability is an important metric used to assess the performance of repairable systems, accounting for both the reliability and maintainability properties of a component or system. Did you know, though, that there are different classifications of availability and different ways to calculate it? This article will explore the different availability classifications, what they mean and how they ...
Performance Measurement of Mining Equipment. ... and classified which are used in definition of availability . ... availability, performance and quality rates which is .
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

performance of BELT equipment. The present paper aims at reviewing the available pertinent literature in the subject field and deals with various aspects of performance measurement of BELT equipment in the mining industry. These indicators which are used for evaluating the performance of BELT equipment are described herewith.
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.
How a focus on equipment performance promises to unlock billions of dollars in productivity returns for miners. ... • Mining equipment in Australia runs at lower annual outputs than most ... between equipment achieving typical availability rates of 85% and those achieving best practice of 90% or more. Again, some examples are ...
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
Monitoring of real-time performance versus plan. One benefit of real-time 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 time.The 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.

Influencing equipment performance through maintenance metrics ... and control the performance and availability of their equipment," say Abelardo Flores and Jim McCaherty, co-authors of "Performance Metrics for Mobile Mining Equipment," a guideline created to assist mining equipment users in the definition and use of uniform ...
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.
