Özet: Günümüzde şehir içi ulaşımı rahatlatmaya yönelik yapılan tünel inşaatlarındaki kazı yöntemleri, tünelin uzunluğu, tünel güzergâhının geçtiği jeolojik birimler…vb. parametrelere göre belirlenmektedir. Çift tüp olarak yaklaşık 1645 m uzunlukta açılan Konak Tünellerinde Yeni Avusturya Tünel Açma (NATM) yöntemi uygulanmış olup, tünel güzergahı Yeşildere caddesi girişinden itibaren başlayıp, 2. Kadriye mahallesi, 1. Kadriye mahallesini takiben Namık Kemal mahallesinden sonra Eğitim Diş Hastanesi ile Etnoğrafya Müzesi arasında son bulmaktadır. Bu çalışmada, İzmir Konak tünelleri inşaatında, patlatmalı kazı sırasında arzu edilen teknik sonuçların ekonomik ve emniyetli limitlerde kalması, patlatmadan kaynaklanan titreşim ve hava şoku gibi çevresel problemlerin en aza indirilmesine izin veren bir yaklaşımla patlatma ön tasarımı yapılmıştır.

“…A large number of researchers have already studied the blasting technique and its impacts on the surrounding environment, so the prediction equations and reduction methods of blast induced ground vibration have been proposed. Most of them adopt Peak Particle Velocity (PPV) to evaluate the degree of blast-induced seismic motion [3] [4]. However, general prediction equations and/or methods have not been developed yet because they do not fully consider the impact of rock mass and geological conditions which experimentally have a clear influence on the propagation behavior of the ground vibrations.…”

In modern mining industry, rock blasting is one of the essential working for rock breakage in terms of economic and efficient aspects. Blast-induced ground vibration may give serious impacts on wide range of surrounding environment, so it has to be paid much attention in the blasting process. Peak Particle Velocity (PPV) is one of the most important parameters related with blast-induced ground vibration. The prediction of PPV is very important in order to design an appropriate blasting standard and minimize its environmental impacts. However, general prediction equations and/or methods have not been developed yet because they do not consider the impact of rock mass and geological conditions. Therefore, in this paper, indoor tests, field tests and numerical simulation were conducted for assessing the effect of fragment in the rock mass on propagation behavior of ground vibration. In order to enable versatile vibration prediction at different sites with different blasting and geological condition, we investigated the differences in vibration behaviors due to blasting design, and the difference in geological condition. The result of a series of tests suggested that fragments in the rock mass related with the damping behavior of the blast-induced ground vibrations and more accurate prediction of the ground vibration (PPV) could be performed by considering fragment condition in the rock mass.

One of the most important operations in mining is blasting. Improper design of blasting pattern will cause technical and safety problems. Considering impact of results of blasting on next steps of mining, correct pattern selection needs a great cautiousness. In selecting of blasting pattern, technical, economical and safety aspects should be considered. Thus, most appropriate pattern selection can be defined as a Multi Attribute Decision Making (MADM) problem. Linear assignment method is one of the very applicable methods in decision making problems. In this paper, this method was used for the first time to evaluate blasting patterns in mine. In this ranking, safety and technical parameters have been considered to evaluate blasting patterns. Finally, blasting pattern with burden of 3.5 m, spacing of 4.5 m, stemming of 3.8 m and hole length of 12.1 m has been presented as the most suitable pattern obtained from linear assignment model for Sungun Copper Mine.
