In order to develop a reliable and effective equipment life cycle model, the stages of equipment life have to be defined. Equipment life can be defined using three different variables namely physical life, economic life and profit life (Mitchell, 1998).Both the physical and economic life must be calculated when considering equipment life because they provide an effective …
The mining equipment efficiency is measured by availability, utilization and productivity (Fourie, 2016). These factors of efficiency of mining equipment vary considerably as a far as
The production performance of Mining Machines/Equipment depends on its availability and utilization. Hence it is necessary to determine the percentage availability and utilization of machinery with an aim to improve the …
that the actual utilization percentage achieved by the equipment is significantly lower than the provided availability percentage of the equipment. The main data collection method used was observing the maintenance and repair activities pertaining to the mining earth moving equipment and the phenomena being researched.
Availability is the most commonly used mining equipment performance metric due to the simplicity of its definition and the easiness of interpretation of its numeric results. Unfortunately, there is no

Besides, absence of auxiliary haulage units and
The present paper aims at reviewing the available pertinent literature in the subject field and deals with various aspects of performance measurement of excavating, loading and transporting...
2021) and to assess mining equipment performance (X. Cao et al., 2021), identifying weak areas in the mining process (Siregar et al., 2018) for improving effectiveness of mining equipment (Samatemba et al., 2020). Therefore, it is necessary to select appropriate parameters which must be routinely monitor. Each mining equipment has its specified

OEE (Overall Equipment Effectiveness) is a key performance indicator (KPI) widely used in performance analysis in the mining industry. The present study develops the ODE indicator (Overall ...
The raw materials extracted from the mining activity are key components in our society and the development of the economy [1].This is particularly important in many countries in terms of internal social and economic development [2, 3].In this regard, there is a direct relationship between availability, reliability, productivity, safety and sustainability [4].
This guideline provides a classification framework for operational activity that will enable meaningful performance analysis and industry-wide comparison. The framework includes the following: Recommendations for the …
There are several metrics that can be used to quantify the reliability of mining equipment, such as mean time between failures (MTBF), mean time to repair (MTTR), availability, and maintainability.
Unexpected occurrence of uneven breakdowns and their consequences have a significant influence on the equipment life. Hence, there is a need to discover the motives for the happening of critical potential failures and required repair or replacement action to control. Reliability analysis is utilized to approximate the performance of the equipment. In this study, …
One issue with calculating equipment availability through traditional means is that each instance must be recorded. This includes downtime, reason, and actual duration. ... In this way, maintenance teams are aware of the performance and health of equipment, and can use the machine condition data to understand how often downtimes occur and the ...
Overall Equipment Effectiveness (OEE) is a well-known measurementmethod, which combines availability, performance and quality, for the evaluation of equipment effectiveness in manufacturing ...
In this case, the analysis was also carried out using the Overall Equipment Effectiveness (OEE) model. Studies [22][23] [24] [25] have also made reference to the effectiveness of mining machines ...
The model is based on an expert system for assessing the availability of continuous mining systems. The availability of the system, as a complex state parameter, is decomposed into the...

This is the first mining truck in the iron ore mining industry in India to achieve this feat. During 60,000 hours of operation, the HD785 Dumper completed 1,29,637 trips and hauled 12.48-million-ton material with 94% equipment availability. products are known for their superior quality and deliver high performance.
This has improved availability and reduced costs by a projected 20 per cent across the remaining life of the fleet. The number of variables that influence the performance of an individual piece of equipment made it very difficult to do this sort of analysis before these systems were developed.
The estimated availability for truck by OEE is 60.67% while that of loader is 43.30% against the bench mark of 90%, the estimated performance for truck by OEE is 94.58% while that of loader is 59. ...
