Sirovision Mapping & Analysis.

Sirovision

Sirovision is developed in collaboration between Datamine and the Commonwealth Scientific and Industrial Research Organisation (CSIRO). Sirovision allows remote and safe capture of geological features while avoiding costly disruption to production activities. Mapping of geological and geotechnical features is supported, along with automatic recognition of mineralogy. Further analysis tools for wedge detection and slope stability provide valuable inputs to geotechnical support designs and for identifying safety hazards in open pits and underground environments.

Benefits

Low Implementation Costs

Uses off the shelf digital SLR cameras and fixed focal length lenses

Safe

Personnel do not have to approach the rock face. The WHOLE face can be photographed and mapped from a distance. Pit walls can be photographed up to 1500 meters away

Trusted

Sirovision is used in open pit operations across five continents by the worlds largest mining companies

Accurate

Typically produces accuracy of 1:3000 to 1:5000 ~ 3cm to 5cm for every 100 meters distance to the rock face.  It produces orientation measurements with an angular accuracy of +/- 0.5 º or better over ranges from 3m to 1500m

Fast

Photographs can be taken easily and rapidly. Different focal length lenses can be used from same positions giving great flexibility in level of detail

Easy to use

Two days training. Requires only basic knowledge of how use a digital camera

Full Integrated Solution

As well as producing 3D images, it allows structural mapping producing highly accurate and instantaneous geotechnical results

Compatible

3D topographical images and structural data can be easily imported into other major mining software such as  STUDIO, Vulcan, Surpac, Dips & Minesight

Capture in 3 Easy Steps

Your result? – A 3D mosaic of images displaying the back, end and side walls of an underground drive.

1.

Take two stereo images

2.

Assign the stereo images together into pairs

3.

Sirovision automated wizards create the 3D image and uses survey data to position it

3D

Visualise

Sirovision enables you to map geology and structure across continuous mosaics of 3D images meaning entire drives, including the back wall, side walls and end wall can be mapped and analysed at the same time. 3D mosaic images and mapped features and their geotechnical characteristics can be exported file formats compatible with most other major mining software packages including DATAMINE STUDIO, SURPAC, VULCAN and MINESIGHT.

Simply click on a mapped discontinuity for its calculated geotechnical characteristics.

Sirovision enables the analysis of digitally mapped discontinuity data with a wide range of useful tools

 

Analysis Explorer

Create Discontinuity Analysis Sets and subsets organised in a windows explorer file structure.

Filter Editor

Design queries to create analysis sets based on any criteria you require.

Schema Editor

Build your own schemas and apply custom data to mapped discontinuity sets. Also Build analysis set reports on customised schema data

What our customers say about us

Glencore

Glencore

‘The quality of the information is a lot better using Sirovision mapping. With [Sirovision] you can see things that you wouldn’t be able to see if your standing 5 meters away to stay clear of unsupported ground.”

Greg Snyder, Geology Lead, Nickel Rim South, Xstrata. Sudbury Mining Solutions Journal, June 2009

Antapaccay

Antapaccay

“The use of Sirovison has helped us in reducing the time in the collection of geotechnical information, analysis and interpretation, as well as contributing to security issues in areas difficult to reach in the banks.
The software is friendly which makes its handling simple.”

William Mendoza, Ingeniero Geotecnico, Antapaccay, April 2017

Acacia Mining PLC

Acacia Mining PLC

“Sirovision has optimized burden and spacing planning for blasting holes planning and improved rock fragmentation through proper understanding of discontinuities and localized rock mass characterization for Buzwagi open pit”

“Geotechnical mapping using Sirovision at Nyabirama pit has improved understanding of the structural model by clear understanding of all significant geological discontinuities hence optimizing various engineering and mine development projects.”

Elias Mtibilo, Engineering Geologist, Acacia Mining PLC, quoted April 2017

AngloGold Ashanti

AngloGold Ashanti

“Following all the updates on Sirovision, it has incredibly helped AngloGold Ashanti-Geita Gold Mine to correctly map all critical and nasty structures in our active pits from both accessible and inaccessible exposed structures and understand how they are sitting against the pit slope, at which by modeling them a level of confidence to all consecutive open pit design is increased through Sirovision data, potentially a right decision is made to maintain or add more value to the company.”
Martine Hamisi, Senior Geotechnical Engineer, Geita Gold Mining, quoted April 2017

Filminera Resources Corporation

Filminera Resources Corporation

“To date I have been finding the accuracy well within our needs and as we are using Sirovision in cycle (every exposed bench ) we are getting within centimeters of check points regularly and the survey I-site scans and Sirovision mirror each other very well.”

Nick Spanswick, Senior Mine Geologist quoted October 2010

New Bolidan Kevitsa

New Bolidan Kevitsa

“Sirovision has been great for us at the Kevitsa Operation as it has allowed us to safely collect high quality mapping data which would not otherwise be possible. We cannot have our people mapping within close proximity of the pit walls – the risk of rock fall is too great. We now safely collect accurate, real-space mapping data for modelling from all our production faces and pit walls. We are super happy with the system and the support we receive.”
Jani Kalla, Chief Geologist, Boliden Kevitsa, quoted April 2017

Eldorado Gold

Eldorado Gold

“Our open pit mine has made a major safety improvement by using Sirovision geotechnical scale (window) mapping technique, which has provided more accurate reflection of true fracturing on slope faces. Increased recorded statistical fracture population has resulted better archiving of slope faces. Number of mapping has appx. 50% increased without compromising safety and quality.”

- Serdar Ergun, Senior Geotechnical Engineer, Kisladag Mine, Eldorado Gold Corporation, quoted April 2017

Stereo Plots, Rose Plots, Contour Plots

Work with analysis sets on a stereo plot whilst visualising their physical structure simultaneously on a 3D image.

For example, you can select a discontinuity on a stereo plot which highlights it on the 3D image. From this 3D image, you can view coordinate values and real world spatial location for the discontinuity. Simultaneously, you can view dip/dip direction and trend/plunge values for the same discontinuity on the spherical projection.

Automatic Wedge Detector

Set geotechnical criteria to automatically detect wedges and plot their plane of intersection.

Statistics

View statistics on selected discontinuity sets such as Joint Persistence Distribution and Joint Spacing Distribution.

Stereo Camera

Capture high resolution 3D underground data quickly and easily

For underground data capture, Datamine has developed the new Stereo Camera Mark II, utilising the latest digital SLR cameras. This unit is designed to take stereo photographs with one touch of a button enabling entire headings to be captured in only a few minutes. Photographs taken with the Mark II unit are used to produce high resolution 16 megapixel 3D images from which minerals and rock can be easily identified, mapped and analysed. Geotechnical tools such as the Slope Stability Analysis tool enables automated wedge detection which outputs the mass, volume and sliding vector of wedges based on geotechnical domain characteristics.
