Bir Taş Ocağı için Ön Patlatma Tasarımı Geliştirilmesi ve Çevresel Etkilerinin Değerlendirilmesi

Abstract

The most commonly used excavation method in the mining, quarry and construction sectors is the drilling and blasting method. This method has many advantages as well as disadvantages in terms of environmental impacts. The most important adverse environmental effects caused by blasting can be said as vibration, air shock and dust emission. In order to minimize these environmental impacts, a proper blasting design plays an active role by taking the principles of controlled blasting into account. In this study, an appropriate pre-blasting design was performed to meet the production capacity increase in a quarry, and the environmental impacts of this design on the settlements and olive groves, which were determined as a critical structure near the quarry, were estimated. The risk of damage to critical structures is found to be low with assessment of the estimated peak particle velocity (PPV) values for the amount of charge per delay in the proposed blasting design model due to the fact that these values are well below the permissible threshold damage limits in the regulation. According to air shock and dust emission value analysis, the estimated values were found to be below the limit values given in the related regulations. As a result, it was determined that the proposed design model for the quarry is a suitable model in terms of its environmental impacts, but the design should be tested with the test shots in the field.
