  A real-time analysis of rock fragmentation using UAV …

  2021811 · Due to these impacts, the measurement of post-blast rock fragmentation is an important metric in the optimization of a mining operation. It is suggested that real-time fragmentation measurement should be implemented to improve blast design over time with the goal of producing an optimal rock size distribution for downstream processes [3].

  The Fragmentation Energy-Fan Model in Quarry Blasts - Rock …

  201849 · This paper investigates fragmentation in an aggregate quarry in the light of the fragmentation-energy fan concept. Six blasts were monitored, located one behind the other in the same quarry area. The rock structure was blocky, the water level and the usage of explosives were variable within and between the blasts; however, the distribution of …

  Maptek - Fragmentation Analysis

  199771 · Some effects of accurate delay time on rock fragmentation have been examined numerically using a newly developed continuum damage model. Stress wave collision created by simultaneously initiating a continuous explosive column from opposite ends is simulated in both an axisymmetric environment and in bench blasting.

  Hard Rock Fragmentation in Percussion Drilling Considering …

  2021121 · The rock samples used in the current investigation were granite without visible cracks (quarried in Liaoning Province, China). Before the hard rock fragmentation test, the physical and mechanical properties were obtained by the ISRM suggested method. The physical and mechanical properties of the rock samples are listed in Table 1. Table 1.
