A typical mining company has three important assets: the human labor-force, the orebody, and the equipment. Trucks, excavators, drilling machines, crushers, grinders, classifiers, and ...

The use of mining equipment often determines the success of a mining project, as it plays a crucial role in all phases of the mining process. As valuable resources are increasingly becoming finite, the availability and utilization of mining equipment can no longer be taken for granted.

The performance of the equipment can be projected by computing the key performance indicators (KPI) such as availability percentage (AP) and utilization percentage (UP). The AP is defined as the percentage of equipment which is readily available to perform the specified task in its work environment known as AP.

Mining equipment is an integral part of the mining process. The availability and utilization of mining equipment can be a major factor to the success or failure of a mining operation. In order to make sure mining equipment availability and utilization is maximized, measures must be taken into consideration to ensure that they …

Availability = Run Time / Planned Production Time. For example, if a machine runs for 8 hours, with 4 hours of downtime, during a 12-hour shift, then the availability for that machine is 66.6%. One issue with calculating equipment availability through traditional means is that each instance must be recorded.

New stochastic simultaneous optimization of extraction sequence and mining equipment. • SIP integrates uncertainties in metal/grade & fleet availability, hauling time etc. • Approach leads to lower cost and minable patterns. • Method leads to efficient fleet allocation, higher & less variable utilization.

Using a piece of equipment effectively depends on its utilization, availability and the age of the equipment. The main objectives of a mining operation are to …

Availability talks about the future and planned usage of a machine's capacity; utilization rate talks about how much a machine's capacity has actually performed and contributed to producing ...

Overall Equipment Effectiveness (OEE) is a well-known measurementmethod, which combines availability, performance and quality, for the evaluation of equipment effectiveness in manufacturing ...

Abstract. This article deals with reliability analysis of mining equipment such as shovels and dumper in a surface coal mine at The Singareni Collieries Co. Ltd., Telangana, by using the RBD and ...

For example, the cost of using a piece of equipment depends on its utilization, the availability and age of the equipment. The ultimate goal of mining operation is to provide the required amount of raw material needed by the community at reduced costs.

Thus, a new method, called Overall Mining Equipment Effectiveness (OMEE), was developed, verifying its appropriateness and flexibility to analyze the …

The mining e quipment ef ficiency is mea sured by availability, utilization and productivity (Fourie, 2016). These factors of efficiency of mining equipment var y considerably as a far as

Availability is a measure of t he usable. quality of technical systems. Increasing the. availability of mining mecha nization en a-. bles the safe and stable production. It is of great importance ...

replacement time of mining equipment through four step: i) Acting; ii) Observing; iis i) Evaluating; and, iv) Planning; analysing four vital parameters: i) Technical availability rate; ii) Mechanical availability rate; iii) Utilization; and, iv) Productivity index. The case study side was an open pit coal mine located in the North-West of Spain.

The best probable utilization of equipment can be possible when the probability of equipment is readily available; the consequence of this should lead to an …

Equipment services being performed at short notice, in an unplanned manner, increasing the downtime associated with these services. These better mining organisations are beginning to focus less on the traditional measures of equipment performance - availability and utilisation, and are starting structured programs to address reliability …

Overall equipment effectiveness (OEE) is a hierarchy of. metrics developed by Seiichi Nakajima in the 1960s to. evaluate how effectively a manufacturing operation is. utilized. It is based on the ...

This research work is carried out to determine the availability and the effective utilization of Chemistry laboratory equipment on students' academic performance in secondary school. The study was guided by two objectives, two research questions and one hypothesis was tested at 0.05 level of significance.

Since mining is a very capital-intensive industry, it is more appreciate to use calendar time-based approach to estimate OEE. 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 ...

Overall equipment effectiveness, also referred to as OEE, is a hierarchy of metrics that focus on how effectively equipment is utilized. The OEE of a machine is the product of its operational availability, utilization of the availability, its productivity, and quality of operation. OEE = Av χ UoAv χ Prod χ Q. where.

In mechanized mining, poor equipment efficiency (availability, utilization, productivity, and quality) can endanger the success of the operation. This case study will show how an initiative to ...

Thus, the performance of the loading unit (i.e. E0752 and E0737) with respect to availability, utilization and production are heterogenuous (different), which supports the usage of the panel data ...

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

'Availability' to one mining company may not have the same meaning to another mining company or to a supplier of mining equipment. In this section, the authors have …

The sustainable development of mining processes requires a deep knowledge of the effectiveness of mining equipment and is quite complex to analyze due to the intrinsic characteristics of the mining industry. In this regard, its measurement and control can lead to appropriate management, improving the mining processes' …

CONCLUSION Availability and utilization study is a known method to measure performance of production equipment in manufacturing industries and adapted for mining industry in this paper. From the above studies various steps can be taken to improve availability and utilization of SDL machine so that its performance is better and …
