Ventilation problems raised with the beginning of underground mining. In underground mining, to provide safe and healthy working conditions, ventilation should be designed properly. Especially in the planning stage of the project, to design ventilation properly is very important. The latest upgrade of the popular ventilation simulation program, known as VnetPC 2000, has been applied for the ventilation design. In this study simulation is conducted to both auxiliary and main ventilation at Çayirhan G Field. Information describing the geometry of a ventilation network, airway characteristics and locations, characteristics of different fans were prepared as an input. The output includes predicted airflows, frictional pressure drops, air power, losses in airway and fan operating points for different trials. After different trials it has been found that for auxiliary ventilation, where minimum required amount of air is 6 m3/s, ENGART, 30A 40SCV/60HR model fan which is the most economical one was selected. For main ventilation system, 5 fans which provide airflow more than minimum requirement were chosen. Among them the most economical one, that is ALPHAIR-5400VAX2100 HB, was selected for the mine.

Production of heavy-media-quality magnetite concentrate from Kesikköprü iron ore tailings
Güngör, Kazım; Atalay, M Ümit; Department of Mining Engineering (2010)
The aim of this research was to investigate the possibility of the production of a magnetite concentrate which is suitable for preparation of heavy media from iron ore tailings of Güncem Mining Company magnetic separation facility. During the study, three different tailings named as low grade, medium grade and high grade with 5.91 % Fe3O4, 19.06 % Fe3O4 and 37.06 % Fe3O4, respectively, were used. Mineralogical analyses of test samples showed that magnetite and hematite were the major ore minerals while pyri...
Comparative study on ground vibrations prediction by statistical and neural networks approaches at Tunçbilek coal mine, panel byh
Akeil, Salah; Bilgin, Hasan Aydın; Department of Mining Engineering (2004)
In this thesis, ground vibrations induced by bench blasting from the Tunçbilek Coal Mine, Panel BYH, were measured to find out the site-specific attenuation and to assess the structural damage risk. A statistical approach is applied to the collected data, and from the data analysis an attenuation relationship is established to be used in predicting the peak particle velocity as well as to calculate the maximum allowable charge per delay. The values of frequencies are also analyzed to investigate the damage ...
Electrical potential response of the quartz bearing rocks under uniaxial loading
İnal, Hikmet Sinan; Bilgin, Hasan Aydın; Department of Mining Engineering (2004)
The electric potential changes under uniaxial loading in some minerals and rocks have long been recognized. To daylight the electrical response of some minerals and rocks against applied stress, both theoretical studies and laboratory experiments are conducted. Some theories are also proposed by different researchers, in order to explain the electric potential variations. However, the mechanisms leading to electrical potential generation have not been fully explained yet. In the explanation of electric pote...
Removal of heavy metals in waste water by using coal fly ash
Tuzcu, Emrah Tuğcan; Atalay, M Ümit; Department of Mining Engineering (2005)
In this research, it is aimed to remove toxic heavy metals in waste water with the help of fly ash from Çayırhan thermal power plant. The chemical and physical properties (size distribution, specific surface area, porosity, chemical composition, etc.) of fly ash were determined. The experiments were carried out in synthetic waste water containing lead, zinc and copper metals at different concentrations with the addition of fly ash. The effects of metal concentration, agitation time, particle size, ash amoun...
Computer modeling of the initial cavern for Beypazari Trona ore on the basis of leaching rates, insoluble contents and thickness of trona layer
Tunçay Saygun, İlkay; Arol, Ali İhsan; Department of Mining Engineering (2008)
Trona ore located in Beypazarı is extracted by solution mining method with well pair connected by directional drilling technology. This thesis covers the determination of the dimensions of the initial (vertical) caverns formed in underground by use of a computer modeling (trademark: WinUbro/Poland) on the basis of horizontal and vertical leaching rates. The leaching rates were determined using the trona core samples from the ore deposit. The effect of insoluble content and the thickness of trona layer and s...
