Khumani Iron Ore Mine, South AfricaOperating since 2008
You can take all the measurements you need but if you don’t have easy and timeous access it does not mean much
Basic Flow Diagram
• Slow access to production data• Integrating data from multiple sources
– different formats, different levels of granularity
• Important data emailed in spreadsheets– e.g laboratory data
• Poor access to long term historical production data – long lead time when requesting data from a vendor
• External consultants/contractors drain resources with data requests
Data Accessibility Issues
• Constant report changes as new managers have different preferences
• Long lead time when requesting report changes from your software vendor
• Software vendor package limitations
Data Visualisation Issues(e.g. reports, dashboards)
Priority No. 1Create a system where non-IT personnel can query data and create their own dashboards or reports.
2. Establish a stable platform of data.3. Create a unified interface for access to all production data.4. Create ‘Plug and Play’ capabilities for new vendor systems to
add/remove their data.5. Create long term continuous data storage and access.6. For IT dept. - Reduce the burden that reporting services create on
source databases
Objectives
Solution
The Use of Common Business Intelligence and Analytics Tools in the Operation and Optimisation of Iron Ore Process Plants.
Microsoft Excel• Everyone knows how to use it
OLAP cube(On-line Analytical Processing)• Technology for processing and then presenting multidimensional
data for analysis• Common business tool that is part of MicroSoft SQL server
• Laboratory or the analyser calibrating team to check the results from 2 sources
• Enable timeous intervention
Metallurgical Uses
Short term planning cycle• Automatically updating short term planning tools (forecasting)
Metallurgical Uses
Met Accounting tools have been created using the OLAP cube in order to:
• monitor the reliability of the weightometer readings,
• check the mass balance across the plant and its sub-sections,
• checking the reliability of the online sizing and chemical analysers,
• perform investigations as required
Before• Diagrams need to be scrutinised
for the correct instrument tags• Hours are spent gathering and
organising all the data• 1000’s of rows of data• Level of granularity has to be
decided up front and then can’t be changed
Using the OLAP cube• New calculation is made in the
cube• Data can be viewed for any
period• Level of granularity can be
changed as required• No data required, can go
straight to chart
Typical Investigation(e.g. Have the solids to the tailings dam increased?)
Finding Required Data
Data analysts with little knowledge of the plant query data and create reports with Excel
• Example of Flow Diagram with Map IDs
Consultants on site
Consultants on site can be shown the cube to access the data themselves
• No training required
• No reliance on mine resources
• Create their own dashboards as required
IT Advantages
• Permanent storage of data separate from the production systems (e.g. production capturing, mine truck and dispatch systems, laboratory information management systems, etc.).
• Relieves the production systems from reporting workload.
• The OLAP cube technology offers faster access to data for BI systems
