Stake face
is selected.
2.
In
Tunnel Settings
,
Tunnel design

3.
In the
Define

Check Jumbo position
and type in the
values. Refer to "Defining the Work".
4.
If
Drilling rig orientation
:
Parallel to alignment
was selected in
Tunnel Settings
,
Tunnel design
page and
Check Jumbo position
was checked in the
Define
panel, then proceed to define the drill
entry position on the tunnel face by entering the respective centre-
line offset in
Stake Face
, page.
5.
In
Stake Face
,
General
page, enter the approximate tunnel face
chainage. To position the laser pointer to the drill entry point press
FnPosition
to find the point.
6.
Position the drill bit to the laser point on the tunnel face.
7.
Now the jumbo boom moves onto line between the laser point on
wall and the telescope so that the laser now points at the back of
the boom. Press
Fn

proceed to define the drill entry position for the measured chainage
by entering the defined chainage centreline offsets in the
Stake

5.
In the

on the measured tunnel face press
Fn

The delta chainage value after using
Fn
Position
is the
difference between the defined and measured chainage. It
is normal if the delta is large. The delta position and delta
height values after this step should equal zero.
