FOREWORD
Pattern Analyser is a graphical software program for the laying blast pattern. It gives engineers and blasting
personnel the ability to the layout initiation sequence of almost any type of bench blasting, as most
commonly used in open cut mining.
It allows the designer to:
Provide surface delays, with tie line connections.
Analyze wave front reinforcement.
Import data and print the design.
Save design to database and as image files in widely used formats.
Individual elements of the pattern are defined by the user and can be combined in a variety of scenario.
Note : Pattern Analyser is best viewed with all functionalities with Google chrome and Mozilla Firefox.

pattern using New option .
5.2.1 Connecting Holes with tie lines
Blast holes are connected with connectors like Shock tube, detonating cord etc. Delays are placed
between holes or rows for effective blasting operation.
Single Tielines
Following is the procedure to draw hole to hole single tieline:
1. Place the mouse cursor on one hole click the hole, that hole will become
activated (i.e. hole with red square outside and filled with blue).
OPERATION MANUAL
25
2. Move the mouse cursor to next hole which is to be connected from active hole. On click next hole blue
color tie line will appear and next hole also activated with red color square outside and filled with blue
color.
3. After that click on last selected hole. User will get tie line between selected holes and holes filled
with blue color with without red square and delay will appear above the hole.
4. Repeat the process 1 – 3 to connect the holes to be tied.
Multiple Tielines
Following is the procedure to draw hole to hole single tieline:
1. Place the mouse cursor on one hole click the hole, that hole will become activated (i.e. hole with
red square outside and filled with blue).
OPERATION MANUAL
26
2. Move the mouse cursor to next hole which is to be connected from active hole. On click selected hole
blue color tie lines will appear between all holes those come in line of selected two holes. All holes also
activated with red color square outside and filled with blue color.
3. After that click on last selected hole. User gets tie lines between all holes and holes filled with blue
color with without red square and delay will appear above the holes.
OPERATION MANUAL
27
4. Repeat the process 1 – 3 to connect the holes to be tied.
5.2.2 Limitations in drawing tieline
Tieline that make a cycle of tielines are not permitted. One cannot make a tieline,which makes hole to be
connected from different holes. A message will be prompted in front of user in case he tries to make such
tieline. This is explainedas below:
Case I: User makes tielines in following manner. This is allowed.
OPERATION MANUAL
28
Case II: User tries to make tieline between highlighted hole in above case and hole with 34 ms delay as
shown in case above. This is not allowed and will result in error message.
5.2.3 Change delay
Pattern Analyser allows changing delay.On changing the delay the next tieline dealy will appear according
to new change delay and holes connected to those tielines will change progressively. This is explained
from following image sequence:
OPERATION MANUAL
29
Step I: Following indicates original blast holes connected with tielines and delay assigned as 17ms.
Step II: User can change delay on click Change Delay button on top of Design panel. On clicking it one
dialog box will appear user can select either from drop down list or by typing in textbox. After selection user
must click on Ok button. (exp: user selected 10 ms delay )
Step III: After that tieline delay will change and result in progressive connected holes will also change
(exp: new tie line from 0 ms delay to 30 ms have 10 ms new selected delay.)
