The planning stages of mining activities require many comprehensive and detailed analyses. Determining the correct orebody model is the first stage and one of the most important. Three-dimensional solid modeling is one of the significant methods that can examine the position and shape of the ore deposit. Although there are many different types of mining software for determining a solid model, many users try to build geological models in the computer without knowing how these software packages work. As researchers on the subject, we wanted to answer the question "How would we do it". For this purpose, a system was developed for generating solid models using data obtained from boreholes. Obtaining this model in an AutoCAD environment will be important for geologists and engineers. Developed programs were first tested with virtual borehole data belonging to a virtual deposit. Then the real borehole data of a cement raw material site were successfully applied. This article allows readers not only to see a clear example of the programming approach to layered deposits but also to produce more complicated software in this context. Our study serves as a window to understanding the geological modeling process.
Özetİş kazaları, ulusal çapta faaliyet gösteren tüm alanlarda ciddiyetle üzerinde durulmaya başlanan önemli konuların başında gelmektedir. Bu gün kanunlarla desteklenen, denetlenen ve kontrol altına alınmaya çalışılan bir ifade olarak önümüzde durmaktadır. Gelecekte hangi durumlarla karşılaşacağımızı öngörebilmek, çalışma yöntemlerini doğru seçebilmek ve alınacak tedbirleri düzenlemek için yakın geçmişten yararlanmak gerekmektedir. Ulusal verileri kullanılarak, iş kazalarına güncel bir bakış sunan bu çalışmada, kazaların sonuçları çeşitli değişkenler kullanılarak sorgulanmıştır. Faaliyet kolları, kaza zamanlaması ve bunlara bağlı ölüm ve geçici iş göremezlik sayıları incelenmiştir.Çalışmada, kaza-zaman yoğunluğu tespit edilmiş ve iş kazalarının zamanlama modeli oluşturulmuştur. Aynı şekilde, mühendislik çalışmalarının iş kazalarının en yoğun olduğu ana faaliyet kolu olduğu ortaya çıkmıştır. Benzer şekilde, inşaat ve madencilik çalışmalarının, kayıpların en çok meydana geldiği faaliyet kolları olduğu tespit edilmiştir. Bu çalışmada ayrıca, iş kazasına bağlı ölümler ile yıllar arasında regresyon analizi ortaya konmuştur. Anahtar Kelimeler: İş kazası, Mühendislik faaliyetleri, Kaza-zaman yoğunluğu, Regresyon analizi Statistical Data Analysis of Current Work Accidents AbstractWork accidents are among the key issues which begun to be addressed seriously in all areas operating nationwide. Today, these accidents are stands as an expression which supported, audited and controlled by law. It is necessary to take advantage of the recent past to predict what situations we face in the future, be able to select the correct operating procedures and to arrange the precautions. In this study which offering an updated overview of work accidents by using national data, the consequences were investigated by different variables. Operating branches, accident timing and the number of death and temporary incapacity for work were examined.In the study, the intensity of accident-time was determined and timing of work accidents is modeled. Also, the engineering work appeared to be main branch of the most intense work accidents. Likewise, it is determined that construction and mining operations are the branches that most losses occurred. Also in this study demonstrated regression analysis between the years with death due to work accidents.
This study aims to find out which method can obtained the most accurate results in less time and at the lowest cost on the basis of element. At the beginning of the study, worldwide researches about this subject are investigated. As a result of this investigation, two of the chemical analysis methods which are widely used in the elemental analysis of the inorganic raw materials used in mining were compared. Then, 15 test samples which have different compositions and generally investigated main element content were determined in order to compare. The samples were analyzed in parallel with atomic absorption spectroscopy (AAS) and energy-dispersive X-ray fluorescence spectrometer (EDXRF). The compatibility and the deviations were determined by comparing the results of the analysis statistically from both methods. It was tried to determine which method can be used for which type of elements. It is observed that the material composition effects choosing appropriate method.
ÖzetTraverten, pek çok avantajı nedeniyle yaygın olarak kullanılan bir kaplama taşıdır. Bu çalışma kapsamında, Elazığ Keban Bölgesinde üretim faaliyetinde bulunan bir sahanın farklı bölgelerinden alınan travertenlerin kaplama taşı olarak kullanılabilirliği TS EN ve BS EN standartlarına göre değerlendirilmiştir. Yapılan çalışmada, görünüş, eğilme dayanımı, su emme katsayısı, yangın karşısındaki davranışı, kılcal etkiyle su emme, açık gözeneklilik, görünür yoğunluk ve don sonrası eğilme dayanımı değerleri bulunmuştur. Çalışma sonucunda; Elazığ travertenlerinin don oluşumu olmayan, az yağış alan bölgelerde kaplama taşı olarak kullanılabileceği sonucu ortaya çıkmıştır. Anahtar Kelimeler: Doğal taş, Elazığ traverten, Kaplama taşı Determination of the Possible Usability of Elazığ Travertine as Cladding Slab AbstractTravertine, is a coating vehicle widely used because of many advantages In this study the usability of Elazığ travertine which is taken from manufacturing fields around the Keban area of Elazığ, as cladding slab is evaluated according to the TS EN and BS EN standards. In this study, appearance, flexural strength, water absorption coefficient, action against fire, capillary action of water absorption, open porosity, apparent density and bending strength value after frost were found. In conclusion; the results has emerged that Elazığ travertine can be used as coating in stone in low rainfall areas without frost formation
