An explosive is considered to be impact sensitive if is can be shown to detonate under exposure to the types of impacts found in normal mining operations.
This would include impact from ground engaging tools (loader and dozer teeth) and drilling operations, crushing between rocks, grinding in a crusher and the like.
It does not include being struck by high velocity (supersonic) projectiles.
Impact sensitivity testing can be completed using the BAM Fall Hammer apparatus developed by the German Federal Institute for Testing Materials (BAM). Impact energy is imparted to a 40mm3 sample by means of a falling weight. The limiting impact energy is determined as the lowest energy at which a flash, flame, or explosion is observed. The test is used to assess the sensitivity of the test material to drop-weight impact. The BAM Fallhammer test is a part of UN Test Series 3 which is used to assess the ignition sensitivity of suspected explosive materials. As many as 54 trials may be performed and therefore approximately 3 cubic centimeters (cc) of sample may be required.
Impact sensitive products are known to have detonated under moderate impacts such would commonly occur in a drill and blast operation.
Sources of impact include drilling, machine excavation, rock crushing and the like.
In its original position or place.
Relates to goods which when mixed or otherwise brought into contact with each other, are likely to interact and increase risk because of the interaction.
Blasting components which provide the transmission of signal, control of delay timing and the initial explosive energy within the blast hole.
Hard copy or electronic plan showing all the blast hole positions and the initiation system with all connections and products specified.
BlastPlan is the premier initiation design application available. www.blastplan.com.au
The location of the first hole in a blast to fire. Also the point at which the lead in line is attached to the pattern.
Is the delay time between rows.
These units of competency are recommended for current Drill and Blast Engineers, Superintendents, Supervisors and Senior Shotfirers wishing to increase both their design and management skills.
Course assessment is by completion of classroom and online components and by assignment submission.
Class size is limited to eight persons on a first come basis.
Course leader is Peter Duniam BE. MPM. Director of Blast Management International with over thirty years industry experience.
