Reliability Modeling and Analysis for Walking Draglines of GLI Mine



Reliability analysis of dragline using fault tree analysis
Deniz, Tuncay; Demirel, Nuray (2017-06-01)
Draglines, as massive and expensive stripping machines, are highly utilized in open cast mining to remove overburden. Reliabilities and availabilities of draglines play a critical role to sustain the continuity of overburden stripping and, hence, coal productions. Thorough understanding of the system and its components is required in order to accomplish high levels of availability and it can be achieved with an in depth reliability analysis. This study presents component-based reliability analysis of a walk...
Reliability analysis for two draglines in Tunçbilek lignite mine
Tuncay, Deniz; Demirel, Nuray; Department of Mining Engineering (2014)
In modern mining activities, high-capacity complex machines are used and their availability plays a big role on the mine productivity. Draglines are one of the high capacity mining machines which result in decrease in production in case of failure or unavailability. This study aims to determine the effects of different components of two draglines (PAGE 736 and MARION 7820) to their availability and operability by choosing adequate reliability models and conducting fault tree analyses. Reliability analysis w...
Reliability-Based Stability Analysis of Rock Slopes Using Numerical Analysis and Response Surface Method
Dadashzadeh, N.; Düzgün, Hafize Şebnem; Yesiloglu-Gultekin, N. (2017-08-01)
While advanced numerical techniques in slope stability analysis are successfully used in deterministic studies, they have so far found limited use in probabilistic analyses due to their high computation cost. The first-order reliability method (FORM) is one of the most efficient probabilistic techniques to perform probabilistic stability analysis by considering the associated uncertainties in the analysis parameters. However, it is not possible to directly use FORM in numerical slope stability evaluations a...
Reliability analysis of a rock slope in Sumela monastery, Turkey, based on discrete element and response surface methods
Dadashzadeh, Neda; Düzgün, H. Şebnem; Department of Mining Engineering (2015)
It is widely recognized that a single factor of safety (FOS) calculated by traditional deterministic analysis methods may not represent slope safety due to involved uncertainties. The First Order Reliability Method (FORM) is one of the extensively used probabilistic methods in slope stability studies to quantify the uncertainties in the parameters. FORM can be easily applied when the slope is analyzed based on limit equilibrium methods. However, the recent numerical techniques are almost substituted by the ...
Reliability-based analysis of time-dependent scouring at bridge abutments
Kerpiççii Kara , Sibel; Yanmaz, Ali Melih; Department of Civil Engineering (2009)
Deterministic scour prediction equations for bridge abutments do not involve uncertainties coming from scouring parameters and they only consider effects of hydraulic parameters. However, in order to safely design bridge abutments, treatment of these uncertainties and evaluation of possible risks are required. Two artificial neural network (ANN) models are constructed to describe scouring phenomenon using the parameters of two different equations. The equation to be used in the reliability analysis is then ...
