Shortest path optimization of haul road design in underground mines using an evolutionary algorithm
Yardımcı, Ahmet Güneş; Karpuz, Celal (Elsevier BV, 2019-10-01)
All types of underground mine access serve as permanent openings to transfer men and extracted material throughout the life of an operation. Development and operating costs are predominantly controlled by the haul road len...
An integrated simulation model for opportunistic maintenance
Gölbaşı, Onur; Turan, M. Olmez; Karpuz, Celal (2019-01-01)
Maintenance policies embody various work packages with different intention of implementation. When and how to perform these work packages for which equipment is always a problem that needs to be solved specific to the mach...
Fuzzy approach for preliminary design of weak rock slopes in lignite mines
Yardımcı, Ahmet Güneş; Karpuz, Celal (Springer Science and Business Media LLC, 2018-02-01)
Rock slope failure modes are either driven by structurally controlled mechanisms (planar, wedge, or toppling failure) or lean upon the highly jointed or weak rock mass (circular failure). Developing practical tools for pre...
Fuzzy Rock Mass Rating: Soft-Computing-Aided Preliminary Stability Analysis of Weak Rock Slopes
YARDIMCI, AHMET GÜNEŞ; Karpuz, Celal (2018-01-01)
Rock mass classification systems are the most commonly used empirical tools in preliminary design of rock slopes. In spite of numerous advantages, these systems lack the common drawbacks of classification systems originate...
Preliminary estimation of rock mass strength using diamond bit drilling operational parameters
BASARIR, H.; Karpuz, Celal (2016-03-03)
In many mining engineering applications such as prospecting, development, production and grouting, diamond bit drilling is widely used due to high penetration rate, core recovery and its ability to drill with less deviatio...
Stability Analysis and Optimized Slope Angle for the Iron Ore Open-Pit Mine
AKDAG, S.; BASARIR, H.; Karpuz, Celal; OZYURT, M. (2015-04-17)
With an increase in the overall slope height of open pit mines, stability analysis and amount of stripping waste rock becomes progressively difficult. It is necessary to optimize the overall slope angle by increasing it as...
Relationship Between Pre-failure and Post-failure Mechanical Properties of Rock Material of Different Origin
Tutluoğlu, Levend; ÖGE, Ibrahim Ferid; Karpuz, Celal (Springer Science and Business Media LLC, 2015-01-01)
Under compression, gathering data related to the post-failure part of the stress-strain curve requires stiff servo-controlled testing systems. In unconfined conditions, data related to the post-peak region of the intact ro...
Penetration rate prediction for diamond bit drilling by adaptive neuro-fuzzy inference system and multiple regressions
BASARIR, HAKAN; Tutluoğlu, Levend; Karpuz, Celal (Elsevier BV, 2014-05-01)
In many mining, civil, and petroleum engineering applications diamond bit drilling is widely used due to high penetration rate, core recovery and its ability to drill with less deviation. Recently, many research have been ...
Geotechnical Considerations for Mining Method Selection of a Potential Underground Iron Ore Mine in Mideastern, Turkey
Karpuz, Celal (null; 2013-10-01)
Geotechnical analysis plays an important role in determining mining method selection. This study presents the geotechnical design analysis of a potential U/G iron ore Mentes Mine at Yahyali province of Kayseri district in ...
Design and implementation of a multimodal transportation cost analysis model for domestic lignite supply in Turkey
Demir, Eylül Ceren; Karpuz, Celal; Demirel, Nuray (2012-11-01)
Transportation cost is the dominant cost and accounts for almost half of the total mining cost in surface mining. Therefore, determining transportation cost is critically important for the economic feasibility of mining pr...
