A Few Timing Concepts Quarry

2012-2-1  The concept of relief is to ensure the rock has adequate time to move into voids created by previously detonated blast holes, along with allowing sufficient time for interaction with other rocks in motion, creating looseness of muckpile and good fragmentation. Consistency comes from considering blast timing in terms of time per distance (ms/m).
