Nuh Bilgin graduated from the Mining Engineering Department of Istanbul Technical University (ITU). Later he accomplished his PhD studies in the University of Newcastle Upon Tyne, UK in 1977 on Mechanical Cutting Characteristics of Some Medium and High Strength Rocks. He joined the Mining Engineering Department of ITU in 1978. He was appointed as a full time professor in 1989. He spent one year in the Colorado School of Mines, USA, and one year in Witwatersrand University, SA as a visiting professor. He has published more than a hundred papers on mechanized mining and tunneling technologies. He is currently doing consultancy to Mining and Tunnelling Companies. Hanifi Copur graduated from the Mining Engineering Department of Istanbul Technical University, and completed his PhD on rock cutting mechanics and mechanical excavation of mines and tunnels at the Colorado School of Mines in 1999. He worked as a research engineer at the Earth Mechanics Institute of the Colorado School Mines between 1995 and 1999. He has been working as an academician in the Mining Engineering Department of the Istanbul Technical University since 1999 and currently works as the head of department and full-professor in the same department. He has written more than 100 national and international scientific and industrial research reports and 130 publications on mechanical mining and tunneling including two books. He is the founder board member and currently vice president of the Turkish Tunnelling Society. Cemal Balci graduated from Mining Engineering Department of Istanbul Technical University. In 2004, he got PhD after completing his thesis on Comparison of Small and Full Scale Rock Cutting Test to Select Mechanized Excavation machines in Mining Engineering Department of Istanbul Technical University, Mine Mechanization and Technology Division. He joined the mechanical excavation research group in Earth Mechanics Institute, Colorado School of Mines between 2001 and 2004 as a researcher. He published numerous papers on mechanized mining and tunneling technologies and worked in many national and international implementation and research projects. He is currently working in Istanbul Technical University as a full professor and board member of Turkish Tunnelling Society. Deniz Tumac graduated from the Mining Engineering Department of Istanbul Technical University (ITU). He received his PhD on mine and tunnel mechanization in 2010. He joined the research group in the College of Earth and Mineral Sciences, Pennsylvania State University in 2010. Since 2012 he is associated with the ITU, first as an Assistant Professor in the Mining Engineering Department and then from 2014 as an Associate Professor in the same department. He has successfully completed several scientific and industrial projects and published many papers related with mechanized mining, quarrying, and tunneling. He is currently working in ITU and is a member of the Turkish Tunnelling Society and Chamber of Mining Engineers of Turkey.
