A classification system based on the relevant rock mass and material properties of the ground and their influence on excavation equipment performance is described. An excavation rating system is proposed utilizing some rock mass and material properties which influence excavation performances; namely, uniaxial compressive strength, hardness, discontinuity spacing, degree of weathering and seismic wave velocity. The work was carried out in operating Turkish surface lignite mines. It is suggested that this system, which is supported by 284 different case studies, can be used for rapid determination of the excavation class, together with the type of equipment to be used.

A comprehensive evaluation of sedimentary zeolites from Turkey as pozzolanic addition of cement- and lime-based binders ÖZEN KARSLI, SEVGİ; Göncüoğlu, Mehmet Cemal; Liguori, B.; de Gennaro, B.; Cappelletti, P.; Gatta, G. D.; Iucolano, F.; Colella, C. (2016-02-15) The pozzolanic action played by five natural zeolite-rich materials (three clinoptilolite- and one each mordenite- and analcime-bearing rocks) coming from Turkey, has been examined, evaluating also the influence of various chemical-physical parameters, such as grain size of the zeolitic materials and nature of the cation present as extra-framework component of the structure. Pozzolan activity has been estimated by the official test of the European Standards and by thermogravimetry, finding a good accordance...
A simplified model for the analysis of machine foundations on a nonsaturated, elastic and linear soil layer Aşık, Mehmet Zülfü (Elsevier BV, 2001-12) A simplified semi-analytical method, which considers advantages of analytical and numerical approaches, is developed to compute the response of a rigid strip and circular machine foundations - subjected to a harmonic excitation - resting on a layer of soil deposit with a noncompliant rock or rock-like material at the base. The method is based on variational principles and minimization of energy using Hamilton's principle. Nondimensional equations are developed for both type of footing resting on a soil laye...
An empirical strength criterion for the Antalya tufa rock, southern Turkey Sopaci, Evrim; Akgün, Haluk; Daemen, Jaak J. K. (Springer Science and Business Media LLC, 2019-09-01) This paper formulates an empirical strength criterion for the heterogeneous Antalya tufa rock mass assuming that the heterogeneity effect is represented by the unit weight and the porosity of the tufa rock, which is highly variable from a geomechanical point of view. Unconstrained non-linear regression analyses have been used to identify the strength criterion and material constants in terms of fitting an equation and determining its regression parameters. Prior to this approach, the fitting of the laborato...
Joint analysis in the rock settlements of Cappadocia, Turkey Sevindi, Gökhan; Toprak, Vedat; Department of Geological Engineering (2003) This thesis attempts to seek a relationship between the joints developed in the ignimbrites and the rock settlements carved in the same units. Orientation of rooms, directions of walls and joints (both in the rooms and in the field) are input data used in the study. Two sites in Cappadocia (Eskigümüşler and Çanlikilise) are selected to investigate the relationship. Both sites are carved within the same ignimbrite (Kizilkaya) and are located on the south-southeastern slopes of the ignimbrite scarp. Measureme...
A probabilistic model for the assessment of uncertainties in the shear strength of rock discontinuities DUZGUN, HSB; Yücemen, Mehmet Semih; Karpuz, Celal (Elsevier BV, 2002-09-01) Discontinuity shear strength plays a critical role in many problems encountered in rock engineering, especially in the design of rock slopes. Since its precise estimation is generally not possible, it is crucial that the errors and uncertainties associated with its estimate be quantified and reflected in the design procedure. In this study, the uncertainties underlying discontinuity shear strength are thoroughly examined and an uncertainty analysis model is developed for the estimation of in situ discontinu...
