A Few Timing Concepts. pcm_admin 02/01/2012, 12:00 am. In the beginning, blasting was relatively simple. The explosive was placed in the holes and the holes were fired. The speed at which the fuse or an igniter cap would burn was the delay timing per explosive round along with different lengths equalling different times (Alfred …
other design elements can be adjusted to improve round design. Drill patterns and explosive loads can be modified, and within drilling equipment limits, hole-size can be changed. Following, is a list of typical considerations that designers should define when they develop new, or attempt improvement to existing, heading rounds.
In terms of ring design, the key design tools that also in uence the choice of the design parameters are drilling equipment, range of explosive types and initiation systems. The design engineer needs to have a thorough appreciation of the capabilities and limitations of each one of these enabling technologies. The key aspects to consider include:
