6.11.3 Signature Hole Analysis
Signature Hole Analysis is a tool available with the optional Blastware Advanced Module that
requires a USB dongle for access. This tool is used to create and analyze theoretical blast
vibration data based on your input range of blast timing parameters and a Signature Hole
Waveform. The signature hole waveform can also be Band Pass Filtered to remove any
unwanted frequencies it might contain. The theoretical waveform produced by this tool can then
be sorted with a wide range of options and stored in a user defined Project Directory.
This tool first creates all the blast Timeline file combinations, based on your input parameters for
the range of different time delays you want to simulate. Then for each channel in the signature
hole waveform it shifts the waveform in time according to these timeline files and adds them
together to produce a simulated waveform. These simulated waveforms are conveniently listed in
a Signature Hole Analysis Table with the delays used to create them, the resulting Peak Particle
Velocities (PPV), Peak Vector Sum (PVS), Dominant FFT frequency and the Upper to Lower
frequency ratio for each channel. This table along with all the timeline files and simulations are
then saved in your project directory.
NOTES:
1. This is a simulation tool and can not replace standard blasting practices and experience.
2. Signature Hole Analysis is another tool to help you optimize and improve your blast
performance.
a. Common Terms
(1) Signature Hole Waveform
Signature Hole Waveform can be:
1. a single hole of explosives that is the same as a single deck used in the production blast.
2. a single hole of explosives that is the same as will be used in a production shot and
contains inter-deck delays
3. a single row of holes that is the same as will be used in a production shot
(2) Timeline Files
A timeline file contains all of the time delays, relative to time zero (the actual initiation time) for
the entire blast. These delays are derived from the Inter-Deck delays, Inter-Hole delays and Inter-
Row delays
(3) Inter-Hole Delay, Inter-Deck Delay, Inter-Row Delay
