GMSI
History
•Gartner Mining: 2007•Proposed an industry collaboration•Resulted in the establishment of EMMMv
Canada 2010mine planning conference
GMSI
Why?
The objective of EMMMv ( the Exploration, Mining, Metals and minerals
vertical) is to:
realise sustainable business- value through collaboration around a
common operating model and, by so doing, enable its members to
put their Business-IT investment into areas of differentiation versus
standard operating practices and support vendors in their delivery of
technical and business solutions to the industry.

What has GMSI done with the Model?
• Replace our Mining Value Chain circa 1998
• Absorb the EM model into our Business Reference Framework exercise – focused architecture process
• Expand the detail by mining method to L3 and in some cases L4
• L0-L2 – generic; L3 mining method specific; L4 client specific; L5 developer conversation
• Add to base of accumulated L4 & L5 info

capacities and constraints, and its
performance
* Existing blast patterns resulting in current
fragmentation
* Geological, geo-technical and geo-
metallurgical data
* Geographical positioning systems
* Existing equipment performance criteria
* Means to conduct optimisation
(spreadsheets, computer models, simulation,
linear programming etc)
* Reconciliation & Variance analysis of
operational activities in place
* Rock handling system in balance
* Improved loading rates
* Improved cycle times
* More energy-efficient transport (eg: haulage
method)
* Reduced (Optimised) costs of ore / rock transport
* Real-time control on rock movement (eg: Right
time, right destination, minimum delays)
* Optimised fleet management (eg: Optimal
capacity, utilization & availability)
