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...
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 ...
Analysis of mine accidents and financial consequences to gli mines
Özkan, Gökay; Güyagüler, Tevfik; Department of Mining Engineering (2007)
The expenditures resulting from work accidents is increasing every year. Among the other work accidents, mine accidents result important loss of time, money and lives. From the point of view of mine accidents, studies about cost of mine accidents need some contributions. In this thesis, cost of mine accidents to worker, employer, and total economy of country will be analysed in the light of data from Ministry of Labour, Social Security and Social Insurance Institution, and Türkiye Coal Enterprises. General ...
Application of Rock Mass Classification Systems for Future Support Design of the Dim Tunnel Near Alanya
Coşar, Songül; Ünal, Erdal; Department of Mining Engineering (2004)
In this thesis, the results of a number of rock mass classification systems applied to Dim-higway tunnel study area are presented. The tunnel ground was classified according to Rock Mas Rating (RMR), Modified Rock mass Rating (M-RMR), Rock mass quality (Q), Geological Strength Index (GSI) and New Austrian Tunneling Method (NATM). Dim Tunnel has a horse-shoe shape, with a diameter of 10 meters and maximum overburden thickness of 70 meters. During studies, the geological and geotechnical characteristics of th...
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...
