Experimental Study of Computer Stimulation of Bench Blasting in Production Scale

Production scale experiment study was carried out in a limestone open-pit for testing the theory and method proposed by the author(Zou, 1987). The results of experiments indicate that the mathematical model and computer programs, which include the consideration of both the three dimentional distributions of the weak planes and the energy densities of explosion stress waves, reflect the physical process of rock bench blasting quite well. The predicted fragment distributions coincide well with the practical fragment distributions measured with the photo-image analysis method proposed by the author(Zou,1989). The paper "A Three Dimensional Mathematical Model for Calculating the Rock Fragmentation by Bench Blasting in the Open-pit"(Zou,1987), which was published in some conferences and journals, has interested some scholors and researchers. In order to test and improve the model, a group of production scale experiments were carried out in a limestone open-pit during 1986-1987. The procedure and results of the experiments are illustrated in this paper.
