8/13/2019 Building Waste Dumps in MineSight

1/39


2/39

Im going to build a waste dump in

this canyon area


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


4/39

In the Data Manager Create a New

Grid Set


5/39

Name that Grid Set and Click Ok


6/39

Set the Grid Set for Plan View and

Accept Defaults Based on Our Project

Area


7/39

I Cant See Anything so I am going

to close my new grid set

I can still

Attach it to the

viewer


8/39

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


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.


10/39

Now I Pick My Chosen Elevation

from the GridsetsClick on the

Little blue

Lined chart


11/39

Up Comes Your Choice of Planes(Left Click to Highlight Your Favorite)


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)


13/39

Im Naming My Dump Folder


14/39

Next I Will Create My Dump Object


15/39

I Will Name My Initial Dump Object


16/39

I Will Then Put it into Edit Mode(So I can put my initial dumps shape into it)


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


18/39

I Will Now Start Creating a Polygon for

the top level surface of my dump


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)


20/39

For My Organization I Will Create A Dump

Slope Geometry Object and Put it in Edit

Mode


21/39


22/39

Left Click My Line to Pick Right

Click to Finish

Note the line is

A pretty red

color


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.


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)


25/39

Set the Dip Direction in Which to

Expand (ie- straight down)

Note the arrow

Pointing the

Direction of the

Perspective

expansion


26/39

Set The Slope

I chose to enter

My slope as

A ratio

In this case 3Units over for

Every unit down


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.


28/39

Now I Will Preview My Dump


29/39

Ill Look Around and Admire My

Handiwork

Okenough

Admiration-

Click apply


30/39

The Task Completes


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


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


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


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


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)


36/39

Im Going to Create An Object for

my new Surface with the dump


37/39

Fire Up My Intersect Surfaces Tool


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


39/39

Now I Will Select the Dump as my

secondary surface in the same way
