    Comparison of blast-induced ground vibration predictors in Seyitomer coal mine
    (CRC PRESS-TAYLOR & FRANCIS GROUP, 2012) Arpaz, E.; Uysal, O.; Tola, Y.; Gorgulu, K.; Cavus, M.; Qian, Q; Zhou, Y
    Blast induced vibration is one of the most important environmental problems in various sectors such as mining, quarry, tunneling and pipeline trenching. Therefore, experts in this field study intensively to eliminate these effects. The majority of these studies focus on the generation of equations for forecasting values of blast induced vibrations. However, experts do not seem to have reached a consensus on the issue of forecasting and preventing blast induced vibration. This can be explained by ground conditions and design parameters that are totally different from each other. In this study, for the purpose of determining estimation performances of 11 equations suggested in literature for blast induced vibration, 93 blasts from 3 panels in Seyitomer Coal Mine in Turkey were observed and they were assessed on the basis of these methods and the method with the highest correlation value was determined.

    Importance of ground properties in the relationship of ground vibration-structural hazard and land application
    (ELSEVIER SCIENCE BV, 2014) Caylak, C.; Kocaslan, A.; Gorgulu, K.; Buyuksarac, A.; Arpaz, E.
    Vibration parameters like frequency, acceleration and particle velocity play an active role in the relationship of ground vibration-structural hazard. These parameters change depending on blasting energy and the properties of rock environment. Therefore, in the first step, rock mass properties and possible directional variation were investigated by using different geophysical methods (electrical resistivity, seismic refraction and multi-channel analysis of surface wave) and current sounding information. Each method offers different sensitivities and resolutions depending on the physical characteristics of different materials. Evaluating these as a whole increased the solubility of the research. According to seismic S- and P-wave velocities, electrical resistivity and sounding information, the study area consists of consecutive sequences of alluvium, clay limestone, tuff and limestone units. And these units show variations from place to place in the study area. In the second stage, evaluations were made according to the structural hazard standards used widely in the literature and components of velocity, acceleration and frequency obtained from blasting vibration seismograph and accelerometers. As a result, it is seen that ground vibrations show different spreading properties in different directions and different hazard risks depending on the geological structure of the region.

    The effects of rock mass properties on blast-Induced vibrations and geophysical properties
    (European Association of Geoscientists and Engineers, EAGE, 2017) Koçaslan Vurur, A.; Görgülu, K.; Arpaz, E.; Karakas, T.
    Intensity of blast-induced vibrations is affected by parameters such as the physical and mechanical properties of rock mass, explosive characteristics and blasting design. This study measured blasting-induced vibrations in the Kangal Open-Pit Coal Mine, the Tülü Open-Pit Boron Mine, the Kırka Open-Pit Boron Mine, and the TKI Çan Coal Mine fields. The results showed highly variable field constants (K=211.25–5955.74 and =0.82–2.32) and damping behaviors according to direction. Rock mass properties and possible directional variation were investigated by using different geophysical methods (electric resistivity, seismic refraction and multi-channel analysis of surface wave) and current sounding information. Then, rock mass rating (RMR), P- and S-wave velocities of the surrounding rocks have been constructed to estimate the peak particle velocities of related blast-induced vibrations. The proposed PPV model has a good correlation coefficient and hence it can be directly used in prediction of blast-induced vibrations in rocks. Standard errors and coefficient of correlations of the predicted blast-induced vibration parameters are obtained with respect to the observed field data. © 2017 European Association of Geoscientists and Engineers EAGE.
