Firing Module

This video, recorded using a pre-release version of DataBlast Ignite 2.9, provides an introduction to the Firing module.

In the Firing module, you can create firing patterns. You can use these firing patterns to view safety data, such as the scaled depth of burial and flyrock ranges.

Scaled Depth of Burial (SDB)

SDB is an empirical measure of blast energy confinement. This is described as "the ratio of the stemming material to the amount of explosive material within a space equivalent to ten hole diameters". (See Tobin, G. (2013, September) The Importance of Energy Containment to the Blast Outcome & Justification for use of Stemming Plugs in Over Burden Removal.)

The higher the SDB, the less surface activity, air blast, noise and heave of material.

Scaled Depth of Burial	Effects
0 to 0.9	Violent flyrock, air blast noise and dust with very fine fragmentation and good craters.
0.9 to 1.4	Controlled blast with good fragmentation and maximum volume of broken rock in collar zone. Acceptable vibration and air blast noise.
1.4 to 1.8	Very controlled blast with courser fragmentation and reduced volume of broken rock in collar zone. No flyrock.
1.8 to 2.4+	Blast with small or insignificant surface disturbance.
