Öğe Diversity of Electrical Conductivity in a Water-Bearing Rock Material(KOZAN OFSET MALBAACILIK SAN VETIC LTD STI, 2001) Gökay, M. K.; Özkan, I.The electrical conductivity of rock materials was analysed in order to develop practical laboratory-based measurement equipment. In order to proceed with the selected aim, artificial rock materials were prepared by using plaster of Paris. Test samples were prepared in two categories: the first was the original material; the second group of samples contained glass pieces. Glass pieces were located in the test samples in a certain pattern to simulate random joint orientation in natural rock masses. The tests showed that, electrical fields around the joints are higher due to their high water-bearing characteristics. This property was used in the tests to determine hidden joint locations in the selected rock masses and model samples provided. Underground gas, water or petroleum storage excavations or excavations opened for waste dumping are all sensitive to seepage of the gases or liquids both into them and out of them. Evaluation of these rock masses for joint occurrence requires at least seismic and electrical conductivity measurements. In this research study, alternative measuring techniques were investigated for laboratory and field test procedures. The resulting graphics obtained in the laboratory tests illustrate how the joints in the rock masses were detected in the samples.Öğe Interaction Matrix Concept Application in Equipment Selection(A A BALKEMA, 1994) Gökay, M.
