The comminution theory applied to rock blasting
- Peruvian Society of Rock Drilling and Blasting, Lima (Peru)
A general review of the comminution theory and also the general differential equation of the comminution are described, analyzed and discussed in order to be applied to rock blasting. Some size distribution functions are reviewed and discussed to determine which of them represents better the cumulative low size distribution F(x) as a function of the nominal particle size (x), for the rock blasting fragmentation. Based on the mathematical comminution model presented, a formula to calculate the burden (B) is developed and discussed. A mathematical comminution model based on the strain energy and applied to an open pit rock blasting operation is developed, analyzed and discussed. The advantages of the mathematical comminution model presented in this paper are emphasized.
