The most widely used method for minimizing blasting vibrations is based on the principle of reducing the amount of explosive per delay. Although the inadequacies of this method are widely cited in the literature and its limitations are often encountered in practice, the method is still used because of the appeal of familiarity and its success at long distances from blasting. In 2007, a new method was developed and patented by us. The software developed in this method supported 30-hole group blasts under the conditions of that period, and its most important handicap was that it was based on the assumption that blasts and the resulting seismic waves behaved "linearly" as in the classical method used today. In our Tübitak project, which is the subject of this paper, we have developed a software that models the nonlinear behavior of blasts and blast-induced seismic waves to overcome this handicap and proposes blast designs that minimize the effects of surface waves, which are the most destructive of blast-induced seismic waves, depending on the group characteristics. In this paper, the software called Seisblast_Plus, the first software in the world to design surface blasting with seismic wave analysis, and the theories such as i) determination of absorption properties with seismic quality factor, ii) determination of internal crush coefficient, iii) determination of the most appropriate delays by calculating the lowest energy with seismic wave analysis and the convenience of these theories in practice are explained.
