The Effects of Accelerated Blast Timing on Primary Crusher

Mar 19, 2020 Notable improved rock fragmentation was achieved as a result of accelerated initiation timing using electronic delay detonators. Analysis showed that primary crusher throughput of that section was 18.5 per cent higher when compared to the reference section. Analysis shows that crusher blockages were reduced by 32.5 per cent in the modified section.

The effects of fragmentation went beyond effects on the dispersal stage in Crataegus because seedling establishment was proportional to the quantities of bird-dispersed seeds arriving at microsites. In contrast, postdispersal mortality in Ilex was so high that it obscured the seed-to-seedling transition. These results suggest that the effects ...
