Im going to build a waste dump in
this canyon area
8/13/2019 Building Waste Dumps in MineSight
3/39
To Do This I Will Do the Following
I will create an edit grid so I can put inhorizontal planer surfaces
I will create a polygon (close pline) at the
top surface of the proposed dump I will use the extrude-expand tool to
project the slope down from the polygon
I will clip my extruded polygon with thesurface intersect tool and make it a part ofmy new surface
8/13/2019 Building Waste Dumps in MineSight
4/39
In the Data Manager Create a New
Grid Set
8/13/2019 Building Waste Dumps in MineSight
5/39
Name that Grid Set and Click Ok
8/13/2019 Building Waste Dumps in MineSight
6/39
Set the Grid Set for Plan View and
Accept Defaults Based on Our Project
Area
8/13/2019 Building Waste Dumps in MineSight
7/39
I Cant See Anything so I am going
to close my new grid set
I can still
Attach it to the
viewer
8/13/2019 Building Waste Dumps in MineSight
8/39
Im Going to Explore for Where I
Want My Dump Top
I turned off the
Surface view so
I could see just
My contours
Then I querriedThe contour line
I was interested in
To get its elevation
8/13/2019 Building Waste Dumps in MineSight
9/39
Now I Will Attach a Grid Set to My
Viewer
First I click on th
Green box to
Attach the
Gridset
It then asks meWhich gridset
I left click to
Highlight my
Choice and
Click ok.
8/13/2019 Building Waste Dumps in MineSight
10/39
Now I Pick My Chosen Elevation
from the GridsetsClick on the
Little blue
Lined chart
8/13/2019 Building Waste Dumps in MineSight
11/39
Up Comes Your Choice of Planes(Left Click to Highlight Your Favorite)
8/13/2019 Building Waste Dumps in MineSight
12/39
Now I Will Set Up the Place to
Store My Dump
For my
Organizational
Plan I will create
A folder that will
Have my dumpStuff in it
(You might
Choose to
Organize
Differently)
8/13/2019 Building Waste Dumps in MineSight
13/39
Im Naming My Dump Folder
8/13/2019 Building Waste Dumps in MineSight
14/39
Next I Will Create My Dump Object
8/13/2019 Building Waste Dumps in MineSight
15/39
I Will Name My Initial Dump Object
8/13/2019 Building Waste Dumps in MineSight
16/39
I Will Then Put it into Edit Mode(So I can put my initial dumps shape into it)
8/13/2019 Building Waste Dumps in MineSight
17/39
I am about to enter the points around
the edge of the dump surface
I will tell the
Computer to
Snap my points
To the plane
Of the edit
grid
8/13/2019 Building Waste Dumps in MineSight
18/39
I Will Now Start Creating a Polygon for
the top level surface of my dump
8/13/2019 Building Waste Dumps in MineSight
19/39
Click to Trace Out the Polygon(That will represent the top level surface of my
dump)Note that my
Polygon extends
Beyond the
Topography
(Thats ok
Because ImGoing to cut
The surface
Anyway)
8/13/2019 Building Waste Dumps in MineSight
20/39
For My Organization I Will Create A Dump
Slope Geometry Object and Put it in Edit
Mode
8/13/2019 Building Waste Dumps in MineSight
21/39
8/13/2019 Building Waste Dumps in MineSight
22/39
Left Click My Line to Pick Right
Click to Finish
Note the line is
A pretty red
color
8/13/2019 Building Waste Dumps in MineSight
23/39
Now Pick Polyline Extrude
Oh what a
Mysteryyou
Have to pick
A line to make
Extrude active
But then it asks
You to pick it
Again.
8/13/2019 Building Waste Dumps in MineSight
24/39
Start Working With the Extrude
WindowWe will give it a
Slope and distance
To expand
(select this option
From the pull-down
Menu)
8/13/2019 Building Waste Dumps in MineSight
25/39
Set the Dip Direction in Which to
Expand (ie- straight down)
Note the arrow
Pointing the
Direction of the
Perspective
expansion
8/13/2019 Building Waste Dumps in MineSight
26/39
Set The Slope
I chose to enter
My slope as
A ratio
In this case 3Units over for
Every unit down
8/13/2019 Building Waste Dumps in MineSight
27/39
Tell it I Want to Create A Dump
Surface
Extrude will
Create a
Second polyline
250 meters
Lower and out750 meters
I will create a
Slope surface
By connecting
Those lines
I also want it
To create a
Top surface for
Me.
8/13/2019 Building Waste Dumps in MineSight
28/39
Now I Will Preview My Dump
8/13/2019 Building Waste Dumps in MineSight
29/39
Ill Look Around and Admire My
Handiwork
Okenough
Admiration-
Click apply
8/13/2019 Building Waste Dumps in MineSight
30/39
The Task Completes
8/13/2019 Building Waste Dumps in MineSight
31/39
I Like This View a Little Better
I turned topo off
The surface
On
Made my dump
Solid instead of
TrianglesAnd set the
Dump color to
Blue
(no you dont
Have to copy my
Picture)
Actually I dont think wed fill in a couple of place
So I would probably go back and adjust my
Dump linesif I were doing a design
8/13/2019 Building Waste Dumps in MineSight
32/39
Next I Would Like to Get the
Volume of My Waste Dump
So I can see how much capacity I have at
a given time
The Following is a Temporary
8/13/2019 Building Waste Dumps in MineSight
33/39
The Following is a Temporary
procedure until a Minesight Surface
Problem is Solved Create an object to store contour lines for your
dump surface
Have Minesight create contours for your dump
surface Have only the following layers on
The topo lines of your pre-dump surface
The topo lines for your dump
Link a horizontal edit grid to your viewer (you did it before in this procedure)
Set volume clipping so that you only see the contoursfor one elevation at a time
8/13/2019 Building Waste Dumps in MineSight
34/39
Continuing the Temporary
Procedure
Create an object for intersecting layers
Create a polygon on each elevation
tracing around the dump contour back to
the original land contour
Obtain the area of the polygon (Query should
do this once you have a close polygon)
Dump contour
Original topo
Trace a polygon
In here
8/13/2019 Building Waste Dumps in MineSight
35/39
Continuing the Temporary
Procedure You will have polygon areas for multiple
elevations (every 20 meters) Where the dump goes below the old surface
obviously you will have no polygon
Take each polygon area and multiply the areaby 20 meters to get a volume in cubic meters
Add the volumes up for the total volume
The technique just described is called average
end area (Minesight will do this automatically with onecommand once the surfaces problem is solved)
8/13/2019 Building Waste Dumps in MineSight
36/39
Im Going to Create An Object for
my new Surface with the dump
8/13/2019 Building Waste Dumps in MineSight
37/39
Fire Up My Intersect Surfaces Tool
8/13/2019 Building Waste Dumps in MineSight
38/39
I Will Select Surfaces to Intersect
I can select either
By picking in the
Viewer
On by picking fro
A menu
The little blue
worm is the
Window pick
Click it
Then click on my
General surface
Then right click
To complete my
selection
8/13/2019 Building Waste Dumps in MineSight
39/39
Now I Will Select the Dump as my
secondary surface in the same way
