Özet
This project was supported by Turkish Coal Enterprises and was carried out at the Ilgın-Konya open pit coal mine. Horizontal displacements along boreholes were measured using an inclinometer at 0.5 m intervals. In the same boreholes, vertical displacements were assessed at 3 m intervals using a magnetic colon probe. To measure in situ displacement, two boreholes were drilled in separate open pit benches and displacements monitored over a 7 month period. We found that the horizontal displacement value was ?10 mm (north-east) in the upper borehole and ?5 mm (north-east) in the lower borehole, with vertical displacements of ?8 mm and ?1 mm, respectively. The shear zones of the unstable mine slopes were determined as 4.5 and 6 m in the upper and lower boreholes respectively. Vertical deformation values, as horizontal displacement measurements, could not be taken every 0.5 m. Therefore, it was encountered with some difficulties in evaluations. Here, based on our data, we developed a method to determinate vertical displacements from inclinometer measurements. By this approach, the estimated vertical displacement values were in line with experimentally-determined (magnetic colon) vertical displacement values. The estimated depths of the shear zone were comparable when using the experimental and mathematically determined displacement values. © 2016 Taylor & Francis Group, London
