Abstract

DelPat program makes possible to design of blasting operations and cost estimation with ground vibration analysis arising from blasting. In this study, these applications of DelPat program were used for blasting works in excavation of Boyabat Dam and H.P.P. (Hydroelectric Power Plant) construction and the results were researched extensively. Blasting design was done and the results of planned blasting works and ground vibration measurements were analyzed by use of DelPat. At the end of some shots, 35 events were recorded by ground vibration monitors and the data which taken from these measurements were evaluated and ground transmission coefficient and specific geological constant were determined. Thus, the equation of site specific ground vibration prediction was asserted. In the result of this study, it is shown that the applicational results are in accordance with the estimations which DelPat made before the blasting. Thus, it’s demonstrated that DelPat could used confidently in blasting design, analyses of blasting results and prediction of particle size distribution, ground vibration, air shock, fly rock and drillingblasting cost.
