This study presents the controlled blasting method used to excavate the buffer zone between a new connection tunnel and an active sewage tunnel operating at full capacity at the Tuzla Advanced Biological Wastewater Treatment Plant in Istanbul, owned by ISKI. Treating up to 650,000 m- of wastewater daily for a population of 2.6 million, the plant required new treatment units to be connected to the existing system due to increased capacity needs. Since the existing 2,200 mm-diameter sewage tunnel, built in 1998, cou...

Decision making can be defined as a selection process of the best one among the alternatives sets in order to obtain goal, and mostly has an uncertain situation. Additionally, mostly linguistic variables (weak rock, massive ore deposit, etc.) become in question. Mine planning engineers often use of their intuition and experiences in decision making. As the fuzzy set theory was carried out since 1970, these uncertainties in question are easily evaluated in decision making process. Real world study is decision makin...

At present, production activities in Can lignite basin, which is belonging to Turkish Coal Enterprise (TKE) are run for domestic purposes. Apart from domestic and industrial consumption, it is also possible to evaluate the Can Lignite Reserve at power plant for meeting energy demand. The aim of this study consists of production planning, mine design and make mine planning activities more efficient, more economic and minimize environmental problems. Involving in this project, Authors have investigated available dri...

Ground vibrations and air blasts are integral part of rock blasting and unavoidable. Depending on level of the stresses produced from wave motion, they cause damage to buildings structures in the nearby residents by causing dynamic stresses that exceed the strength of building material or rock material. So ground vibration effects induced by blasting on building structures and human beings need to be predicted, monitored and controlled. In other words, prediction of ground vibration components is of great importan...
