Advanced
Projections is a flexible routine that is an extension of
Basic Projections. Besides
creating projections this routine can also draw pillars and perimeter
by using the Draw Pillars option.
Other options include angling the crosscuts, offsetting entries,
variable length entries, and
different labeling schemes. All projection lines are on distinct layers
(PROJECTIONS, PROJSTOPPINGS,PROJVENTARROWS). The pillars are
drawn by default in the PILLARS layer and the perimeter is drawn by
default in the PERIM layer.

Note: The length
of the panel was shortened for display
purposes. The PILLARS and PERIM layers are reserved layer names
used
in other routines in Carlson. The layer names can be changed
here if you have other reasons to do so.
If you want to
display the centerlines with the projections and be
prompted for ventilation symbols (stoppings and ventilation arrows),
then at the Panel Settings dialog box uncheck the Draw Outline and
Pillars only checkbox.
The following
panel layout is drawn without the ventilation
stoppings or arrows.
Then you will see the Stoppings & Ventilation dialog box and upon filling it out you will be prompted as follows:

Upon
filling in the
prompts, the map will be drawn as shown above.
Angled
Projections
It is possible to
plot projections as
centerlines, as pillars with a perimeter, or both.
Within the Pillars section of the dialog, if the three
dialog items on the left (Draw Pillars, Draw Outline,
Pillars/Outline only) are selected, then only pillars and
perimeters are drawn. This type of projection is particularly useful
to represent the actual mine for purposes of scheduling
equipment, using the Advanced Mining Module. Here is an example of
angled projections, with a "winged" look created by angling only the
first 2 of 4 left and right entries:
If all 4 entries
left and right are angled (rather than the 2
above), then the entire projection
would be in angled form.
Add Rooms
Typical, Default
Room Plotting requires that you
click on the left-side Draw Pillars, Draw Outline and
Pillars/Outline only, as well as click `Add Rooms'. A
typical 2 left, 2 right standard projection with 120'
longrooms (current default) has the following dialog
appearance and plot.
The default angles lean the left rooms to the left and the right rooms to the right at 60 degrees. The crosscut spacing on the longrooms default to ½ the crosscut spacing on the main projections (60 in our case). I have noticed some irregular rooms if you use different crosscut spacing left and right—in that case, it might be better to plot the right side or left side separately. If the Join Perimeter with Center option is not selected, the projections will be in 3 parts: left, center and right. The outer left and right "extents" of the perimeter default to 30' plus the distance to the center of the left- and right-most entries. In our case, that distance to the far entry is 2*120=240, meaning that the outer punchout is defaulting to 270' left and right. I can change that addition of 30' to any other desired number.
Rooms with
Stubouts: You can add stub-outs within the
main dialog, and the rooms will attach appropriately. In this
example, Stub-out L and Stub-out R were set to 30.
Joining with Center Section: The next variation is to join a left or right section to the center (we don't allow joining all 3 at present). This can be done with or without stub-outs. To activate this option, turn on the Join Perimeter with Center option in the Room Dimensions dialog. Shown below is a left section joined to the center with no stubs involved. Below that is a right section joined with the center with stub-outs. The perimeters have been made bold for emphasis.
Rooms with stubouts connected to a standard panel |
Changing Angles in the Rooms: Rooms can have a variety of angles for cutting through. To allow variation in angles, turn on the Angle Left Prompt in the Room Dimensions dialog. In this example, we did _60 (the default), then 60 and 60 in 3 entry left room. We did not vary the right condition. The prompting for the angle will remember the last entry, so the second "60" becomes just an "Enter" default on the left side.

Rooms with entry spacing variations |
Entry Spacing Prompt: We can also choose to vary the spacing. In the example below, we did 0 left entries and 3 right entries, and we varied the entry spacing prompt on the right (and included stub-outs and Join Perimeter with Center). We entered 100, 140 and 120 for the three entry spacings and obtained the plot shown below:
Plotting Rooms
with No Central
Projection: This is useful for attaching left and right rooms to
an existing mine plot. You pick your "centerline" as normal to get
starting, but you answer 0 to
both the number of left and right entries. Normally, this would simply
exit the routine, but a new
prompt asks "Do Longroom (y/n)". Enter "y" and you can place rooms to
the left or right. (The
program will only do one side or the other in a "no central panel"
projection scheme. Repeat the
process to add a right side to the left side rooms.) Here is the
"look" of a left-side, 3 room section with
no central projection:
Perpendicular Rooms and Offset Rooms
If the Room
Dimension dialog is completed as shown below, rooms can
be drawn at 90 degrees
to the main entry, and can be offset as many crosscuts as desired. The
offset up is measured
by counting the number of room-size crosscuts. So if you have 40x40
rooms coming off 80x80
mains, and want to offset two main-size crosscuts (160 feet to the
first rooms), then enter 4 (4*40 is
160) for the number of crosscuts to offset. Here is the result:
