Unit #4 Carlson Software
Carlson is an Autocad Overlay
• Designed to build specialized commands into
a widely used drawing package
• Largely 2D or a highly layered 3D
• Dimensional limitations and the adding of
commands to a basically familiar package
speeds learning and familiarizing
Used Heavily in the Coal Industry
• Most coal is mined in near level seams of fairly
uniform thickness
• Carlson has done an excellent job
– Adding dragline simulation into surface coal
mining
– Highly integrated with day to day surveying
• Performance in non-uniform and irregular 3D
such as metals and industrial minerals is
generally behind the competition
Coal Mine Planning
• Generally starts with drill hole data
• You import the data into Carlson
• Carlson can extrapolate the data across a grid
that can be used for contours
– Carlson can estimate reserves and quality off of
contours
• Alternatively Carlson can build a block model
to work from
Continuing
• Once reserves are defined you plan out your
entries
• Carlson allows you to describe things like entries
and pillar sizes and then it draws things out
instantly
– Tremendous time savings vs. what it would take to do
the same in MineSight
• When the layout is complete you can put in
mining rate information and Carlson will time out
your panels for you.
A Different Kind of Unit
• I do not know Carlson like I know MineSight
• In this unit I have taken Carlson videos and
seminar papers and tried to piece together an
outline to train you
– It will also mean that not all software will be
taught to you in one format
• Good – Bad? I guess you’ll decide
An Outline
• For 3 weeks
– I will take Monday and Tuesday for economic
considerations
– Thursday we will not hold class – you will run a
self study self pace
• Frankly my ability to help is limited because I am not a
Carlson man
• You will be producing a single project with
your work that you turn in at the end.
The Information
• The first articles and videos will cover
– Setting up Carlson
– Understanding Carlson’s geology modeling
– Importing of drill hole data
– Preparing either data grids or block models
– Estimating reserves
• The next articles and videos will deal with
drawing panels and entries and timing mining
operations.
Your Project
This block of ground is 3 miles north to south and 5 miles east to west.
At the south end the coal is 8 feet thick, but at the north end it is only 3 feet
thick. The coal thins in a linear fashion to the north. At the south end the
sulfur is 3.5%. At the north end the sulfur is 0.9%. The sulfur content again
varies linearly. You need to produce a coal product of not more than 2%
sulfur through the life of your mine. You will be doing 3 million tons of coal
per year with room and pillar supersection. Your depth is 500 feet. Coal
strength is typical of Illinois #6 coal. Assume you have a sandstone floor with
no weak floor underclays. Draw me a resonable mine layout and time your
mining using Carlson software.
