    Aug 24, 2017· To start blasting, the first-row blast holes are blasted with detonators no. 1 and or 2, and then the blast holes in the next row are blasted with a 2-unit delay. The delay between 2 consecutive detonators is 25 ms. A delay of 0.05 s is applied to ensure the efficiency of explosion between two rows of blast holes and to improve fragmentation.
