Quarrying Process And Quarry Products. A stone quarry typically produces the following products Large size blocks blasted from the quarry face from approximately m 3 (approximately tonne weight) to m 3 (approximately 56 tonne weight) are called rip rap or rock armour and are used in coastal and river flood defence schemes to shore up sea fronts and river banks.
BLASTING One of the most common complaints associated with a quarry operation is the blasting. When an explosive is detonated enormous amounts of energy are released. While some of the energy of a blast works to displace rock from the quarry face the remaining energy is released as vibrations through and along the surface of the earth and
Blasting today is not simply about breaking the rock into manageable pieces but properly fragmenting and placing that rock to minimise overall quarry costs and environmental effects. • Anthony Konya is the senior project engineer and Dr Calvin J Konya the founder and president of Precision Blasting Services (USA).
The prediction of the average size of fragments in blasted rock piles produced after blasting in aggregate quarries is essential for decresing the cost of crushing and secondary breaking. There are several conventional and advanced processes to estimate the size of blasted rocks. Among these the empirical prediction of the expected fragmentation in most cases is carried out by Kuznetsov s
