Blastware Advanced Module
Blastware Operator Manual 6–63
These are the typical delays used in the design of a blast. They will be used during the signature
hole analysis process
(4) Band Pass Filter
Specifies the range of frequencies to retain. Frequencies outside this range will be filtered out.
(5) Frequency Ratio
This is a ratio of the content of the lower frequency range to the content of the upper frequency
range
b. Signature Hole Waveform Parameters
The Signature Hole Waveform as defined in section “a (1)” MUST be representative of the
actual production blast. The hole(s) must be:
1. Fully burdened, free-face, and a corner blast
2. A Single-Deck, Multi-Deck, Entire-Row
3. Must have the same diameter and depth as the Production Blast
4. Completed with the same type of explosive
5. For consistent results, ensure that the Signature Hole and Production Blast are
monitored from the same location.
Basic assumptions for the use of the Signature Hole Analysis tool are that the geology across the
Signature Hole and the Production Blast will remain constant, that each hole will produce
identical vibration results, and that the seismograph was consistently positioned and correctly
installed.
Below is an example of a Signature Hole:
c. Access the Signature Hole Analysis Tool
To access the Signature Hole Analysis tool:
1. Select a Signature Hole Waveform in the Event Manager,
2. Click on the Analysis icon. The Waveform Analysis window opens.
3. From Event Manager menu, select Tools > Blast Design Simulations > Signature
Hole Analysis.
