Using MineSight for to Explore
Open Stoping
©2009 Dr. B. C. Paul
Note- This slide set uses views taken from Mintec’s MineSight
software program and utilizes files created for Mintec Underground
training or from their seminars for demonstration purposes.
What is MineSight?
• It is a mine planning and design computer
software package
– It works in true 3D Cad making it suitable for
complex underground metal mines and
structures
• This slide set and following assignment
are intended to orient you only to basic
operations of views and visualizing within
the program.
Why a Computer Package?
• Most mines today use one or more
computer packages to speed the
engineers design process and productivity
– The ability to do computer aided design will
increase your marketability and speed of
orientation to engineering jobs in industry
Why MineSight?
• There are multiple packages out there
–
–
–
–
–
MineSight
Vulcan
Datamine
Gemcon
Carlson
• Each has a following
– SIU has MineSight and Carlson
• Knowing one makes picking up another easier
since they do similar things with varying ease
and efficiency.
Limitations Comments
• Carlson is easiest to learn
– Has very limited 3D visualization (its an autocad
overlay)
– Was built for underground coal with simple deposit
bedding
• Applications are very focused on day to day cad mapping
– Planning Optimization functions and routines are limited
• Has the best survey input connectivity in the business
– Very good for using surveys to keep up mine maps or advance
operations
• About 90% of coal industry in U.S. uses
– Performance for true 3D metals, industrial minerals or
more complex coal is poor
True 3D Packages
• Datamine came out of a computer
graphics company
– Has some remarkable visual tricks including
3D movies
– Allows variable size blocks to be used for
deposits
• Very helpful for underground vein deposits
– Does not have the add on features of for mine
planning
• Was developed to capitalize on graphics more
than mining
More True 3D
• Gemcon
– Functions highly broken down by modules
– Little simpler than some true 3D but lacks versatility
and forces assumptions and approximations.
• Vulcan
– Part of a more comprehensive software company
– Prob better underground than surface
– Prob one of most windows like
• Software design not strictly mine focused
• Prob most like MineSight
• Reputed to be one of the most unfriendly and hard to use
MineSight
• Was born out of software development in Mining
in the 1960s
– Built up an independent 3D interface
– Prob the most comprehensive set of optimization
programs in the business
– Still a Mining focused software company
– Built for and dominates open pit metal
– (We also have a number of alums there and get really
good service)
– For flat 2D bedded deposits the flexibility (and
required decision making that comes with it)
resembles nuking an ant hill
Starting Up MineSight
(of course you can
Do this from a
Desktop icon too).
Click Start Select All Programs Pick MineSight Select MS3D
MineSight’s “Splash Screen” comes
up
Click browse to
Work your way
To the directory
Where your
Assignment files
Are located
If you have been
Working a lot of
Projects recently
You can pick
From a drop down
List (since this
Will be a first time
For you this won’t
Happen now)
The Browse Screen Comes Up
The browse
Screen works just
Like windows
And windows
exploring
Pick the Starting Directory and
Click Ok
The Directory Comes Up in the
Screen
Click Ok
MineSight Will Start Up
(your opening a completed project)
The viewer is
Where you
See you image
Data Manager
Is a two
Tiered Windows
Explorer
The top level
Shows where
The folder is
The bottom
Shows whats
In the folder
More Features
Drop down
Menus at the top
Bring up options
And function
Icons provide
Short cuts to many
Of the most used
Functions
The information line
Shows coordinates
And distances etc.
The message
Window tells you
What MineSight is
Looking for next.
Lets Experiment with Data
Manager and See How it Works
Use a click of your
Left mouse button
To pick 2007
Seminar in the
Data Manager
Note the plus
Beside it – left click
The plus
(Ok this is just like
Picking things in
Windows – not so
Hard for people
With computer
Experience)
Note Clicking the Plus Expands
and shows the files below
(Yes this works just like Windows Exploring)
Left click on the
Completed
Development
Folder to pick it
(it turns blue)
Note that the
Bottom part of
Data Manager
Now shows you
What files are
In the folder.
We Can Close Everything
Left click 2007
Seminar to
Pick the folder
Right click – up
Comes the popUp
Move the curser
Over close until
It turns blue
Left click it to
Close everything
In that folder.
We Are About to Examine an
Underground Open Stoping Mine
Move your curser
Over 3ddevp in
The upper part of
Data Manager and
Left click it.
(yes it turned blue
And all the files in
It appeared in
The lower window
Of Data Manager.
Lets Take a Look at How Our Mine
is Accessed
Move your mouse
Over 3Dshafts
And X cuts in
The lower part of
Data Manager.
Left click with
Your mouse. The
Selection will
Turn blue.
Now without
Moving your
Mouse right click.
This will bring up
A Pop-Up Menu
Move Your Curser Up the Menu to
Open (note that options turn blue as the curser
moves over the top)
When you get
To open left
Click it with your
Mouse.
We See Our Shaft Coming from the surface
and going down to 4 different shaft stations
From each
Station on the shaft
There is a cross-cut
That moves toward
The orebody
The shaft continues
Down below the
Bottom station to
An ore pocket at the
Base where ore
Can be collected and
Hoisted to the surface
Note What Happened in Data
Manager
The 3D Shaft &
Xcuts file turned
Red. (This means
The file is open
In the viewer)
I Wonder How the Ore Gets Down to that
Ore Pocket at the Bottom of the Shaft
Move your curser
To 3Drockpass in
The lower window
Of Data Manager
And left click (pick
It so it turns blue)
Now right click for
The pop-up menu
Move your curser
To open and
Right click it
There is the Rock Pass
Equipment in the
Underground mine
Carries ore to
The rock pass
And dumps it
Down the shoot
Where it goes to
The ore pocket.
LHD Moving Ore
Use the Same Procedure To Open
3Dfwhaulage
Equipment drives
Around underground
In the haulage
Drifts.
Note that the
Cross-cuts from
The shaft stations
Provide access
To the haulage
Drifts.
Note also that the
Haulage drifts go
Over to the ore
Pass.
Miners and Equipment Like to
Breath
We can use our
Object opening
Procedure to open
3Dvents.
We can see that
The underground
Haulage ways
Go to air shafts
Where fresh air
Can be circulated
Into the mine.
One Problem With Underground Equipment
is Moving it from One Level to Another
Many mine
Shafts are not
Big enough to
Allow fully
Assembled
Equipment to
Move from one
Level to another
So the often
Build ramps for
Equipment to
Drive from one
Area to another
We used our
Open procedure
To open
3D ramps.
Our View is Now Getting A Little
Hard to See
Move your mouse
Over to the viewer.
Depress and hold
Both the left and
Right mouse keys
And move the
mouse
Note that you can rotate the angle
you view the mine from
Now hold down
The left mouse
Button and the
Center button or
Roller
Move the mouse
Down.
Note that you Zoom Out – That
didn’t help us see much
Holding the same
Left and center
Mouse buttons down
Move your mouse
up
Note That You Zoom In
Now hold down
The right and
Center mouse
Button and move
Your mouse
Note that you can pan around the
screen
Move your
Mouse around
And try to look
At things to
Help you better
Understand how
The underground
Mine works.
Here is Another View
When Things Were Rotten
Sometimes you
Are trying to pan
And rotate around
And you can’t keep
Your object
Centered and it
Rotates right off
The screen.
You Are Suffering From a Poorly
Placed Viewing Camera
To fix things, pan
Your view back
Onto the screen
Left Click the Pretty Camera Icon
Then left click
A spot near the
Center of the
Object you are
Looking at.
Now the camera
Is close to your
Object and
Your rotations
Will stay on
screen
Much Better
We Know They Are Mining Ore But
Where is it?
In the top of
Data Manager
Left click on
Plnore
Now in the lower
Part of Data
Manager use
Your opening
Procedure and
Open 66-solid.
Note that in most Underground Mining the
mine working are put in underneath the
orebody
We say that we
Are putting our
Development in
The footwall.
(you can imagine
What would
Happen if we
Put them in the
“hanging wall”
And then mined
Out a hole
Underground that
Things caved
Into later – ie
Dropped out from
Under you).
When We Rotate Around to Look At Things
we find some views kind of blocked
Lets try some
Tricks
Move your mouse
Over to 66 solid
And make sure it
Is blue (ie – has
Been picked by
Left clicking). Now
Right click to get
The pop-up menu
Highlight and Select Properties
The Object Properties Window
Opens
We can change
The way
Surfaces are
Displayed.
Point your mouse
To wireframe
Only and left
Click the radio
Button.
Well I Can Definitely See Through that but
Wireframes confuse some people
Ok – I’m going to
Left click faces
Only and loose
The wireframe
I might like to play
With the color
Just for grins and
A little detour –
Left click the
Global Color icon
Up Comes My Color Pallet
I think I will pick
A light yellow
By left clicking
It and then
Left clicking Ok
(this looks pretty
Much like the
Standard color
Pallet stuff most
Windows
Programs have)
Hmm – I wonder what I can do for
solid gold.
One thing I kind
Of dislike about
Surface is that it
Still looks like
A rough web of
Triangles
(it was made by
Triangulating
Between contour
Lines of the ore
Body)
Left click on the
Surfaces tab of
The Object
Properties
If I Left Click on the box by Smooth Shading
it Smoothes those rough edges
Hay I Found a Cure to My Orebody
Hiding My Mine Works
I left clicked the
Transparent
Faces box and
Then increased
The number
Beside it – the
Higher the number
The more seeThrough (this is
75)
I’m going to
Left click ok to
Get out of this
For now.
I Think I Will Get My Surface
showing too
I picked Topo on
The upper part
Of Data Manager
And then used my
Opening procedure
On the tri-topo
File.
MineSight lets you
Set up and name
Files and folders for
Things as you like
So the naming
Scheme for things
Can very with the
Designer.
These Views are Nice But How Do
We Know What to Mine?
Computer models
Divide orebodies
Up into stacked
Blocks. The
Average grade of
Each block as
Well as other
Information about
That part of the
Ore is stored in
The program.
These are called
Block Models.
Lets take a look at our block model
Left click on the
Pln-ore folder
In the top of
Data Manager
This time Right Click the Folder
After it is Picked
A pop up menu
Appears here
Too
Move the curser
Over close so
That it turns blue
-Then left click it
(The trick here is
That I can open
Or close
Everything in a
Whole folder this
Way)
Go to Data Manager and Left Click
on Model
Now go to UG66
In the lower part
Of Data Manager
And use your
Opening
Procedure.
Now We See A Block Model of
Ore Body
The block color
Coding actually
Represents how
Rich the ore is.
Now Lets Think About Planning
an Open Stope Mining Sequence to Get
This Good Stuff
Often When We Mine We Plan to
Go After the Best Ore First
I like the looks of
This stuff
Open Stoping Takes Ore Out of the Ground
leaving an open void behind
Here you see
The first stope
Of ore I dug
Out. You can
Also see it hits
Some of the
Juiciest ore blocks
Around
(Ok you also
Noticed that I
Made my block
Model partly
Transparent so
You could see
What I was
Wacking out)
I Think I Will Go After the Next Best
Ore on the Top Level
Next I think I will
Go to the best
Ore on the level
Below.
MineSight Has a Part Called Activity Planner that
Can Keep Track of My Ore Grades from Stopes as
I Mine them.
I think I will try
Going in here
next
The View Shows all My
Underground Support Workings
In practice as
I see where I
Will go first I
May develop
All the
Underground
Workings in the
Order needed
To stay ahead
Of mining.
(The fact that
The production
Shaft lined up
With the first ore
I would mine
Was not an
Accident)
And So I Continue to Sequence for
the Best and Most Profitable Ore
Eventually We Are Left With a Series of
Hollow Open Stopes in the Ground
The ground is
Now supported
By pillars that run
Across the top of
The open stopes
(Called Crown
Pillars)
A pillars between
Open stopes
(sometimes called
Ribs or Rib
Pillars)
And Pillars Between Stopes
These are
Called ribs,
Or rib pillars
The Value of the Ore Remaining in
Pillars Determines What Happens Next
If the ore in the
Pillars is valuable
Enough the open
Stopes are
Filled with mixtures
Of sand (or mill
Tailings) and
Cement
With the Stopes Backfilled Mining
of the Pillars Can Begin
The Pillars Can Be Mined
(Frequently some backfilling will be required)
Wow!
Wait a minute –
The background
Was black –
What happened?
The Funny Little Blue List is the
Viewer Properties
Left click on the
Viewer properties
Up Comes the Viewer Properties
Window
The background
Color is controlled
From the little
Color pallet
Down here
Left click on it
Pick Your Color With a Left Click
Then left click ok
Hmm – Ok Hot Pink is a Little Over
the Top
The Lighting Tab lets you Adjust Lighting
Effects on Your Mine Drawing
I bet you figured
Out that I left
Clicked my
Viewer properties
And changed the
Background
Color back before
Going here to
Play with the
Lighting.
I Can Go for the Spot Light
Left click the little
Pull down arrow
Move the curser
Over the spot light
To turn it blue
And then left click.
You Can Experiment with Lighting
Effects
With Spot Light
With Distant Light
I Can Also Change the Color And
Brightness of the Lights
Ok – Maybe that light effect
Kind of stinks.
Of Course We Still Have Not Explained How We
Got the Rest of the Way Over to the Ore Body to
Mine It
Cross Cuts Are Developed From the Foot
Wall Haulage Drifts to the Orebody
You Then Develop A Drill Drive
Down the Center of the Deposit
From the drill
Drive drilling
Will be done
Up into the
Orebody to blast
Down ore.
The ore can be
Pulled out using
LHDs working
From the
Cross-cuts into
The orebody
(If you suspect I
Turned off the
Ramp to clear up
The view you
Are right)
Jumbo Drill Advancing A Drill Drift
Stopes Are Started By Putting Up
Slot Raises from the Drill Drifts
In order to blast
Ore there has
To be a place
For the broken
Rock to go.
The first slice
Of ore will be
Blown into the
Slot raise.
Once A Slice Has been Cut Out all Across
the Orebody Later Slices are Blasted into
that Void
There Are Variations of Open Stoping That
Depend Mostly on Where the Drill Drifts are
Located
Some varieties
Put the drill drift
On top of the
Stope.
Other have drill
Drifts on the
Sides of the
orebody
Your Assignment Opportunity
• In this assignment you will perform work
and then document your work using
screen shots that you will save to a Word
document.
Get A View That You Want on Your
Screen
On your
Keyboard
Depress the
Control and
Print screen
Keys at the
Same time
Go to Your Word Document and
Left Click the Paste Icon
Now For the Things You Get to
Show
• Start MineSight and Take a Screenshot of your “splash
screen”
• When the Project Opens Take a Screen Shot.
• Go to the 3D Development Folder and open the shaft
and crosscuts, footwall haulage drifts, Rock Pass, Vent
shafts, and ramp – take a screen shot
• Rotate your view around and take another screen shot
• Zoom in and take a screen shot
• Zoom out and take a screen shot
• Zoom to a convenient point and pan your view and take
a screen shot.
• Change the background color of your viewer and take
another screen shot.
Continued Work
• Go to the plnore folder and open the file 66solid – take a
screen shot
• Rotate your workings around so you can see where they
are relative to your ore body – take a screen shot
• Now adjust your ore body to have a smooth, semitransparent surface so that you can see your mine
workings from the hanging wall side of the orebody –
take a screen shot.
• Turn in your word document with your name and the
required screen shots.
• Also go to the working directory for your project and find
the file msAudit.txt and make a copy of this file to turn in.
• Note that this assignment is best submitted by e-mail
attaching a word file and a copy of the msAudit.txt file.
