    A different view for the spoil slope instability analysis
    (2009) Delibalta, M. Suat
    Many open-spaces and slopes are generated during or after production and overburden stripping in coal open pits. These land fields of which geometries are deformed depending on the overburden thickness, the size of the operation and the mining technique selected, directly impact the effectiveness of the reclamation process and in turn proper preparation of the land for public use. The mining land field soil is often tended to slide and flow due to its structural and stability properties. These sudden changes can reach to high speeds within seconds and often result in massive energy discharges which can cause catastrophic land slides. It is our hope that this present work will shed light to understand and predict the risk of slope stability so that this hypoplastic materials theory (?2E) can be safely used as an alternative technique.

    Predicting the noise level during sawing of carbonate rocks from the P-wave velocity
    (International Commission for Acoustics (ICA), 2019) Kahraman, Sair; Delibalta, M. Suat; Comakli, Ramazan
    Noise affects humans both physically and psychologically, whose impacts vary from person to person. Block cutting machine is one of the most important noise sources in the stone processing plants. This study investigates the predictability of the noise level generated during sawing of carbonate rocks from the P-wave velocity. First, the P-wave velocities of rock samples were measured in the laboratory. Then, the core samples were cut by an automatic cutting machine with diamond saw in the laboratory and noise levels were measured. A strong linear correlation was found between the noise levels and the P-wave velocity. After including the densities of the samples to the analysis, the correlation coefficient was increased significantly. It is concluded that the noise level of carbonate rocks can be estimated using the derived equations from the P-wave velocity. The laboratory noise level can be converted to the site noise level using a conversion factor. © 2019 Proceedings of the International Congress on Acoustics. All rights reserved.

    Recent energy policies and strategic developments in Turkey
    (TAYLOR & FRANCIS INC, 2016) Delibalta, M. Suat
    The increase in demand for energy worldwide and its environmental impacts lead countries to more strategic energy policies. There are no risk-free energy sources in terms of security of supply or environmental impacts. However, more efficient methods are more environmentalist or eco-friendly systems. In parallel with the recent high rates of economic growth in Turkey, the annual increase in consumption growth rate reached an average of 5.59% in the last 11 years. Between 2004 and 2014, electricity consumption increased from 150 billion kWh - 1.70 times - to 255.5 billion kWh. Among the electrical energy installed capacity of Turkey, production obtained from hydraulic sources was 35%, natural gas 30.1%, coal 20.5%, and geothermal + wind + solar sources 6.4%. The share of other sources was 8%. In 2014, with 250.4 billion kWh electric generation, Turkey was ranked 19th globally. It's global share was 1.1%. Turkey's energy sector, which has been based upon on three fundamental pillars (natural gas, coal, and hydraulic) so far, is now being reorganized as a five-pillared structure, including renewable energy sources and nuclear energy. This study discusses the energy overview and new strategic developments to demonstrate Turkey's recent energy policies on the international arena.
