One of the most critical parameters in the determination of optimal blasting conditions is the powder factor. Accurate prediction of the powder factor reduces the costs incurred through trial-and-error blasting. Previous research to establish the initial powder factor has focused on relations between rock mass propert…

The customary approach used in the blast vibration analysis is to derive empirical relations between the peak particle velocities of blast-induced waves and the scaled distance, and to develop patterns limiting the amounts of explosives. During the periods when excavations involving blasting were performed at sites fa…

Concrete dams are important structures due to retaining amount of water on their reservoir. So such kind of structures have to be designed against static and dynamic loads. Especially considering on critical importance against blastingthreats and environmental safety, dams have to be examined according to the blast lo…

From all of the environmental problems, blast-induced vibrations often cause concern to surrounding residents. It is often claimed that damage to building superstructures is due to blasting, and sometimes the building owner files a lawsuit against the company that perform blasting operations. The blast-vibration probl…

In bench blast design, not only the technical and economical aspects, such as block size, uniformity and cost, but also the elimination of environmental problems resulting from ground vibration and air blast should be taken into consideration. Prediction of ground vibration components is of great importance when respo…

The ground vibrations caused by bench blasting at open pit mines have been explored since the 1930’s and several approaches have been made regarding the damage criteria. In all these studies, the amount of explosives and distance to the blasting points are taken as basis as the main variable of ground vibration while…

This paper presents the investigation of the effect of ground vibration components induced blasting events in Ordu-Mesudiye Highway Topçam tunnel on the penstock pipe (PP) having 35-400 slopping of Topçam Hydro-Electrical Power Plant (HEPP). Until the tunnel excavation passed under the PP of HEPP, a total of 37 shots…
