Öğe Açık maden ocaklarının matematiksel modellemesi(Selçuk Üniversitesi Fen Bilimleri Enstitüsü, 1998-08-27) Turanboy, Alparslan; Gökay, Mehmet KemalBu çalışmada, kaya kütlesi içinde açılan açık maden ocaklarının genel şekilleri ve içerdikleri süreksizlikler, analitik geometri kurallarıyla sınıflandırılmış ve geometrileri matematiksel olarak ifade edilmiştir, öne sürülen bu yöntemde, şev eğrileri ve süreksizlikler bir prizma içinde üç boyutlu olarak koordinatlarına göre çizimleri elde edilmiştir. Bu model görüntüleme işlemlerinde, izometrik perspektif yöntemi kullanılmıştır. Elde edilen matematiksel ifadeler ve yaklaşımlar, Doğankuzu Güney Blok Boksit Ocağı (Seydişehir) üzerinde, iki kesim için denenmiştir. Oluşturulan izometrik görüntülerle, ocak eğrileri ve şev yüzeyinde izlenebilen süreksizlikler arasında benzerlik sağlanmıştır. Modelin geliştirilebileceği ve bu aşamada, planlama ve işletme faaliyetlerinde ön fikir verme amacıyla kullanılabileceği önerilmiştir.Öğe An approach to geometrical modelling of slope curves and discontinuities(ELSEVIER SCIENCE BV, 2008) Turanboy, Alparslan; Goekay, M. Kemal; Uelker, ErkanConventional geometrical methods for mining applications such as geologic mapping, cross-sections, logging, stereo-nets, contours and others are so sophisticated that often additional explanations are needed. After studying conventional geometrical methods, we decided to analyze both general slope curves and discontinuities of open pit mines used in excavations in rock mass to achieve meaningful 3D results by using linear mathematical transformation and isometric perspective methods. In addition, a new reorganization of discontinuities as a construction method has been developed according to their spatial orientations. In the developed method, slope curves and discontinuities were geometrically analyzed in a rectangular prism. An example of a detailed structural study of the Dogankuzu South Block Bauxite Open Pit Mine in Seydisehir, Turkey is given. Results indicate that there is a high similarity in both slope curves and discontinuity traces on free surfaces. The main aim of this study is to present a fast and practical visualization of these structures using directly conventional surveying instruments such as theodolite and compass-clinometer or periodic product maps. Present limitations of the method and further studies are also stipulated. (C) 2008 Elsevier B.V.

Kaya kütlesi özelliklerinin ve onun bileşenleri olan süreksizliklerin dağılımlarını ortaya çıkarmaya yönelik bu araştırma çalışmasında şu sonuçlar elde edilmiştir. İncelenen kayaçlar, orta sertlikte ve süreksizlik aralık değerleri negatif eksponansiyel ve log-normal dağılıma yaklaşmaktadır. Düşey kesitler boyunca bu dağılımlar belirgin bir değişim göstermemektedir.Öğe A Geometric Approach for Natural Rock Blocks in Engineering Structures(Grup Matbaacilik, 2009) Turanboy, AlparslanThe spatial positions of the discontinuities and the shapes of rock blocks that are bounded into rock masses are important features that should be taken into consideration, especially to further comprehend the sliding mechanisms in rock media. Therefore, explicit representation of in situ rock mass structures is strongly required in many areas of mining and construction engineering. In this paper, a new classification of two discontinuities as a construction method is developed according to their spatial orientations and their location relative to each other. In addition, in the developed method, discontinuities were geometrically analyzed in a rectangular prism. Thus, the geometries of the possible sliding blocks in engineering structures, such as road cuts, open slopes, or dam walls founded on rock media, were produced. Several basic mathematical equations, and approaches derived from them, were used. In addition, the isometric perspective method was used to for illustrations. The results obtained from two experiment fields show the effectiveness of the proposed modeling method.Öğe A Geometric Approach for Natural Rock Blocks in Engineering Structures(Springer, 2010) Turanboy, AlparslanThe spatial positions of the discontinuities and the shapes of rock blocks that are bounded into rock masses are important features that should be taken into consideration, especially in an effort to better understand the mechanisms in which a rock fails under a load. Therefore, explicit descriptions of in situ rock mass structures are necessary in many areas of mining and construction engineering. In this paper, new geometrical classifications of two discontinuities as a construction method are developed according to the spatial orientations of the discontinuities and their locations relative to each other. Discontinuities were geometrically analyzed using a rectangular prism as an engineering structure. Thus, the geometries of the possible failure of rock blocks in engineering structures were generated and included road cuts, open slopes, and dam walls that are founded in rock media. Several basic mathematical equations and approaches derived from these equations were used. Thus, wedge forms bounded by two discontinuities and free surfaces were geometrically identified and classified. In addition, the isometric perspective method was used to better illustrate the methodology. The results obtained from two experiment fields show the effectiveness of the proposed modeling method.Öğe Investigation of Discontinuities Spacing Histograms by The Use Machine Learning Method(Selçuk Üniversitesi, 2012) Uzun, Yusuf; Turanboy, Alparslan; Tezel, GülayDiscontinuities are major geological features in the rock mass and discontinuity spacing is one of the important parameters in describing the rock mass. Relation between discontinuity spacing and relative spacing has described by different curve fittings. These curve fittings will show the type (negative exponential, log-normal or normal distribution) of the statistical distribution as histograms. Discontinuity spacing and frequency data obtained at a field site in southern Seydişehir (Turkey). Sampling methods vary from one study to another (core sampling, scan-line survey, aerial photograpy). In this study, the possible distributions of discontinuity spacing along a straight line through a rock mass are considered. In this study, 5 different drilling sampling have been used. We have examined discontinuity spacing and relative spacing relations that obtained from these core sampling with using machine learning method. Machine learning, a branch of artificial intelligence, is a scientific discipline that is concerned with the design and development of algorithms that allow computers to evolve behaviors based on empirical data. Minitab (LEAD Technologies, Inc) and Weka (Waikato Environment for Knowledge Analysis) software where preferred in all analyses and interprets. Results of study, different empirical equation for each histogram have been constituted. Machine learning method has been treated on the obtained equations and reached interesting outputs.Öğe LIP-RM: an attempt at 3D visualization of in situ rock mass structures(SPRINGER, 2008) Turanboy, Alparslan; Ulker, ErkanMapping of rock mass structure is an important task required in many applications of mining and contracture engineering. This task has to be routinely performed using established techniques developed to provide consistent results under the wide range conditions. In this research, a new methodology was developed to achieve this task by only utilizing the basic measurement instruments which were compass-clinometer and tape meter. The method's logic was based on the alternatives of spatial position of discontinuities that are classified under four types according to the north. In the developed approach, the geometry of discontinuities was evaluated as the linear relationships. Besides, isometric presentation was preferred in developed 3D simulation software, which was named as "linear isometric projection of rock mass". Input data of the developed software were the discontinuity geometric features such as dip, dip direction, and spacing on the rocky outcrop in the form of an information system. The output was a simulation model consisting of the rock mass structure. The new software derived from the developed approaches was tested on an experimental road wall outcrop. Obtained results are very close to the situation observed in the field, and the developed software is user-friendly. In this paper, a description of the numerical model and current capabilities of the software are introduced.Öğe Maximum volume cuboids for arbitrarily shaped in-situ rock blocks as determined by discontinuity analysis-A genetic algorithm approach(PERGAMON-ELSEVIER SCIENCE LTD, 2009) Ulker, Erkan; Turanboy, AlparslanThe block stone industry is one of the main commercial use of rock. The economic potential of any block quarry depends on the recovery rate, which is defined as the total volume of useful rough blocks extractable from a fixed rock volume in relation to the total volume of moved material. The natural fracture system, the rock type(s) and the extraction method used directly influence the recovery rate. The major aims of this study are to establish a theoretical framework for optimising the extraction process in marble quarries for a given fracture system, and for predicting the recovery rate of the excavated blocks. We have developed a new approach by taking into consideration only the fracture structure for maximum block recovery in block quarries. The complete model uses a linear approach based on basic geometric features of discontinuities for 3D models, a tree structure (TS) for individual investigation and finally a genetic algorithm (GA) for the obtained cuboid volume(s). We tested our new model in a selected marble quarry in the town of iscehisar (AFYONKARAHISAR-TURKEY). (C) 2009 Elsevier Ltd.

Being able to map the structure of a rock mass is crucial to understanding its potential behaviour. This understanding can positively impact on the safety and efficiency of an engineering project. In this research, rock masses were modelled and analysed using linear mathematical transformations and isometric perspective methods to achieve meaningful three-dimensional results. The rock mass fracture representation is based on explicit modelling of rock faces. The developed model can improve safety and productivity through its application in the determination and analysis of rock mass structure for geological and geotechnical assessment. Based on the methods explained here, a software system was developed for analysing the geometric characteristics of discontinuities in a rock mass. In this model, discontinuities in a rock mass can be visualised both individually and in combination, and cross-sections can be generated at any desired location. In addition, intersection lines between discontinuities can be generated as dip direction vectors. The natural structure attained by using this developed model agrees well with field measurements.Öğe A New Classification System and Movement Solutions for Wedge Failure(Crc Press-Taylor & Francis Group, 2010) Turanboy, AlparslanThe determination of the geometrical features of failure modes is the first step in slope design and planning applications. In addition, it is well known that wedge rock blocks are the most common failure mode type. This paper presents the basic components of an approach for establishing the geometry of wedge rock blocks of fractured rocks. A simple new classification system was developed for the construction of the model. The main advantage of this new geometric model is that it presents more practical and rapid solutions for potential failure mechanisms than other classical solutions. The results obtained from an experimental field show the effectiveness of the proposed modeling method.
