Abstract:
Ground vibration is one of the most unfavorable consequences of the blasting operation in open pit mines, which assign about 40 percent of explosive energy. Ground vibration may cause some unsuitable effects such as destroying the surface structures, damaging the free face and generate back breaks, generating the over-size boulders and imposing additional costs to the mine because of the secondary blasting. Optimum blasting pattern design can help to reduce the above mentioned problems. Due to multiplicity of effective parameters and complexity of interactions among these parameters, empirical methods may not be fully appropriate for blasting pattern design. In this paper, using a combination of the Grey analysis and Genetic algorithm, addition to developing a new equation for estimating the ground vibration in Sarcheshmeh Copper Mine, blasting pattern is presented. The results show that with applying the proposed blasting pattern the average ground vibration will be decreased about 55 percent.
