Geophysical Exploration, Blasting Parameters and Fragmentation in Quarries

The paper deals with results of geophysical survey of rock masses, and the blasting parameters which have effect on the fragmentation in quarries. A relationship between the burden, which is the distance between the charged borehole and the free rock surface, and the velocity of longitudinal waves in the rock mass is established based on measured values for different quarries. It is shown that the drilling geometry can also be determined from this relationship.
