SiroJoint
SiroJoint is an
exciting new technology developed by CSIRO that uses a digital camera and terrestrial photogrammetry to
provide 3D geotechnical maps of rock faces quickly and safely. You get data
from places where people cannot go.
SiroJoint generates a picture of a rock face highlighting structures that you
have picked
and showing how they might extend behind the rock face and a data file with the
orientation and position of each of those structures.
The
Sirojoint model can be exported as a dxf file of the 3D digital terrain model (DTM)
to use in your mine planning package for example.
There are some some powerful analytical tools in SiroJoint or you can
export your data for analysis using tools like Dips.
To date over 40 Sirojoint licenses have been sold. The system is being used in
metalliferous and coal mines both open cut and underground at a number of sites
in Australia. Additionally,
licenses
have been sold
into America, Finland, Korea.
Paul Maconochie was the leader of the project
that developed the original version of SiroJoint. He has continued his
involvement with the technology and GTS can offer the use of SiroJoint on a
commercial basis.
GTS has ongoing projects in the Bowen Basin using Sirojoint and can provide a
total SiroJoint service or a partial service in which images that you have
captured are assembled into a DTM and are analysed to provide the data that you
require. Open Cut Coal Mining
GTS is
providing design information for a number of open cut mine sites in the Bowen
Basin, Central Queensland. Thirty years ago the best coal deposits were selected. Many of those mines have reached their maximum economic depth. New open pit mines however, do not always enjoy the
same favourable geology that many of the older
mines enjoyed.
Steep dip, poor floor or geological structures are
challenges in many newer mines. Careful attention to the geology, evaluation of material properties, slope stability
analysis and close liaison with mine planners is required to achieve success. Ongoing site evaluation as new sections of a pit are opened is
essential to check that design assumptions are matched by field conditions.
Spoil dump stability
analysis is usually data limited and so for many purposes 2D limiting equilibrium methods are appropriate, using material strength values that have been determined through research, back analysis and experience. GTS uses
Galena as its preferred slope
stability program to analyse
these problems because it is the only program to come from an English speaking
country to implement the Sarma method of analysis.
The Sarma method is considered by many practitioners to be the most appropriate limiting equilibrium method for analysing spoil dump failures
because the models most closely emulate observations.
