Blastware Compliance Module
Blastware Operator Manual 4–71
Note to Series II users: Blastware contains two Event Managers: the Series III Event Manager
described in this section, and the Series II Event Manager. These menus are toggled by selecting
the unit type at either the bottom left corner of the Event Manager window, or under the Unit,
Select Unit Type menu selection. The Series II Event Manager displays the Events stored on
your Series II monitor, and is used to copy Events to your PC. Once you have copied an Event
over to your PC, you use the Event Manager to view and edit it. Previous and new Series II
Events will be converted to Series III Events and the original files will be saved in the Series II
directory:
DRIVE:/BLASTWARE/BW_SERIES2_BACKUP/”Unit Serial Number”
The Series II folder is automatically created prior to the conversion.
4.3 Tools Menu
The Tools Menu contains three commands in Compliance Mode, Scaled Distance, Post Event
Notes, and ASCII Conversion.
4.3.1 Scaled Distance
The Scaled Distance menu invokes the Scaled Distance window, which contains commands for
performing Scaled Distance Analysis. Scaled distance analysis is a useful tool for quickly and
confidently calculating the maximum charge weight per delay and the minimum safe structure
distance for a specific blast site. The information is presented in a simple and easy-to-read
regression line graph.
The analysis is based on blast data for a site. Scaled distances (SD) and the peak particle velocities
(PPV) are used as coordinates to plot points on a graph with logarithmic axes. SD is plotted on the
X axis, and PPV is plotted on the Y axis. Since there is a correlation between SD and PPV, a
regression line is computed using the least squares method. This is a straight line which “predicts”
with a specified confidence level whether a new data point will reside above or below the line.
Both square root and cube root scaling can be used.
Event data from any Series III or Series IV monitor can be loaded automatically, while data from
other Events can be entered manually. Blastware can also read files saved by the Series II DS-550
Scaled Distance Program.
To open the Scaled Distance window, click once on the Scaled Distance menu.
The Scaled Distance window displays summary information describing the Events, including the
Peak Particle Velocity (PPV), the charge weight, and the distance.
a. File Menu
This menu contains the New, Load, Save, Print and Exit commands.
(1) New
The New command is used to create a new scaled distance file (.sdf). Each scaled distance file
contains data from a number of blast Events, which you enter manually in the Edit Scaled
Distance Record dialog box. (You can also add Events using the Event Manager, as described
below). Once you have made all the settings for one Event, click on OK. The Event appears in the
