Development of a multi-scenario simulation model for spare parts inventory optimization in mining operations Şenses, Sena; Gölbaşı, Onur; Department of Mining Engineering (2021-8) The growing market competition compels many industries to change their operational structures at strategic and operational levels dramatically. It has been recognized that inventory management requires continuous monitorin...
Microscopic fuel consumption modelling for haulage trucks using discrete-event simulation Kına, Elif; Gölbaşı, Onur; Department of Mining Engineering (2021-2-5) Mining is one of the machine-intensive sectors, and a vast amount of energy is consumed in many stages of mining operations. Among these operations, haulage systems hold a significant share in energy consumption. At this p...
Development of a virtual reality-based serious game for occupational health and safety training in underground mining Gürer, Servet; Erkayaoğlu, Mustafa; Sürer, Elif; Department of Mining Engineering (2021-2-5) Mining is a hazardous multi-disciplinary sector for workers and the working environment. It can be said that one of the most important methods to combat these risks is training. These pieces of training are usually given w...
Uncertainty assessment for the supply chain system of a concrete company using Monte Carlo Simulation. Serbest, İnanç Taha; Gölbaşı, Onur; Department of Mining Engineering (2021-2) Concrete is the primary construction material and may be supplied in varying strength values according to customer demand. The profitability of concrete operations is very low, with a profit margin changing between 0.1 and...
Creep behaviour analysis of thin spray-on liners Güner, Doğukan; Öztürk, Hasan; Department of Mining Engineering (2020) Thin Spray-on Liner (TSL) is a relatively thin (2–5 mm) and fast-setting liner material used by spraying onto rock surfaces to support underground excavations. Areal support materials that are sprayed onto the rock, such a...
Tensile opening mode fracture toughness measurements and size effect investigations with Brazilian disc type rock specimens Şar, Elifnaz .; Tutluoğlu, Levend; Department of Mining Engineering (2020) The flattened Brazilian disc(FBD)geometrieswere subjected to compressive loads at the loading ends. Tensile stresses were generated indirectly at the center of the disc specimens. Cracks were initiated, and they propagated...
Thermographic analysis of heat generation during ucs testing of rocks Kırmacı, Alper; Erkayaoğlu, Mustafa; Department of Mining Engineering (2020) SMining activities concentrate on the production of underground resources for energy generation and raw material requirements worldwide, as it is also the case in Turkey. For this reason, the exploration of new resources p...
Effect of loading span on tensile mode fracture toughness for three-point bend specimen geometries Karataş Batan, Ceren; Tutluoğlu, Levend; Department of Mining Engineering (2020) Straight notched disk bending specimen geometry has a potential to find size independent mode I fracture toughness, since the thickness of the disk loaded by threepoint bending can be increased. Increasing the thickness an...
In-situ stress magnitude and orientation determination of Ankara Kazan district from FMI log Karadeniz, Kutay Emre; Öztürk, Hasan; Department of Mining Engineering (2019) Wellbore instability is a major problem in the oil and gas industry. Rock failures occur around the borehole when the induced local stresses exceed the rock strength. Borehole breakouts and drilling-induced fractures (DIFs...
A New approach to 3-dimensional optimization of ultimate pit geometry for open pit mines with variable overall slope angles Altuntov, Firdevs Kübra; Erkayaoğlu, Mustafa; Department of Mining Engineering (2019) The mining activities have high economic risks and the determination of the optimum ultimate pit limit of an ore body greatly affects the economic feasibility of an open pit mine. Due to necessity of determining optimum pi...
Investigation of fracture toughness on flattened Brazilian disc type molded shotcrete specimens Yoncacı, Selin; Tutluoğlu, Levend; Department of Mining Engineering (2019) Monitoring behavior of cracks generated by various reasons in shotcrete/concrete is of crucial importance for the stability of structures in various industries. Despite the need of understanding the crack initiation and pr...
