availability and utilization of mining equipment

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.

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.

Therefore, serious efforts should be made by the mining companies to achieve and maintain the level of higher availability and utilization for capital intensive equipment. ...

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 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.

The analysis concerns to availability of utilization selected mining machinery, conducted using the model of OEE, which is a tool for quantitative estimate strategy TPM.

the availability, utilization, working and ef ciency of mining equipment. We also give a very simple method of recording data necessary for their determinations.

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 ...

In this review, the published scientific, professional articles and doctoral dissertations on the topic of the availability of mining mechanization are presented, showing the measures …

It was proved 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 maintance and repair activities pertaining to the mining earth moving equipment and the phenomena being …

According Kansake and Suglo (2015); and Elevli and Elevli (2010) much research have been done on selection of mine equipment and policies to improve equipment availability and utilization, however ...

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.

Availability and utilization are the key performance indicators of equipment and this is a usual tool for decision-making by management in the mine operation.

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

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

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 ...

The availability of mining mechanization is a key factor for stable exploitation, and this feature of the equipment is the subject of a long-term and detailed study. In this review, the published scientific, professional articles and doctoral dissertations on the topic of the availability of mining mechanization are presented.

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 …

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 ...

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 ...

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 …

The availability forecast is a key step in the maintenance managemen t. process, whereby costs are anticipated and actions can be taken to maintain and. improve the reliability of the fleet. The ...

Due to operational advantage of dragline in simultaneous excavation and back-filling, the equipment has gained vast importance in open-pit mining. Besides, absence of auxiliary haulage units and a myriad of other benefits are also credited in favor of excavation of muck piles by the draglines. However, the aspects of production, productivity and economics …

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 …

2 Accurate Costing in a Non-utilisation Model. Firstly, we show how we can produce accurate costing in a non-utilisation model. In such a model, we assume that the number of hours that a piece of equipment works in any time period (given its equipment type, age, and the operating hours of the mine) is pre-determined.

'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 …
