Özet

© IMCET 2022. All rights reserved.The most used excavation method in the construction and mining industry is blasting. Seismic waves caused by blasting within the scope of engineering projects can cause damage to structures in the vicinity and also cause stability problems. In order to prevent these negativities, blast patterns are created by using the scaled distance theory. Blasting is done with these patterns. However, in order to create a reliable pattern with the scaled distance concept, 20-30 separate blasting data is needed. This can be costly, time consuming and cause negativity. In this study, group blast signals were simulated using blast pattern data generated from data from a single pilot hole with a previously patented model and these data were analyzed by 3D dynamic numerical modeling method. The results show that the seismic signals obtained from a single pilot hole can predict the effects of group blasting on the field.
