Stress-strain-electrical resistance characterization of rock material under uniaxial loading
(UCEAT-CHAMBER MINING ENGINEERS TURNKEY, 2007) Oezkan, I.; Bilim, N.
It has been studied in this study that the stress-strain-electrical resistance behaviour of some rock units was determined under uniaxial compression. The nine different rock units encountered in Konya region were selected for this study and then 27 NX-cores were prepared from them. In this research, uniaxial compressive strength, deformability and electrical resistance tests were carried out by servo-controlled hydraulic press which has 3000kN capacity. While the stress-strain curves obtained from tests were graphed, the electrical resistance-strain curves were also added into these graphs. The stress-strain and electrical resistance-strain curves were evaluated, comparing with each other. As a result, it has been determined that the electrical resistance measurements will be able to be used in order to determine the stress-strain behaviour of rock design like underground mining pillar.
