9. IBMQI Overview Purpose Manage Noise at Source - “Critical Control”
To provide the Mining Industry Leaders with a consolidated industry-wide strategy for an Industry-wide Buy and Maintain Quiet Initiative (IBMQI) as well as a practical path-forward to execute the strategy
Manage Noise at Source - “Critical Control”
Noise is an Engineering problem
Noise source measurements, after-effect analysis etc. – Occupational Health domain
Its cheaper to manage source
What is it?
A standing decision from mining companies to procure equipment and maintain existing equipment that comply with specific noise emission requirements

10. IBMQI Sub-working Groups
Measurements and Standards
Noise Measurement Methodology Guideline
Compiling a noise source inventory
Independent certification and verification guidelines (both for new and old machines)
Research Consolidation
Review previous and current research and inform future research
Interview the technology experts
IBMQI
Industry-wide Buy and Maintain Quiet Initiative
3 Sub Working Groups
Procurement
Prioritization of critical equipment; and
Review critical equipment and identify the noise reduction-target setting

11. Noise Reduction Process
Screening process should now highlight ‘Critical Equipment’
Discussions can now be held between Engineer / Health Practitioner / Commodity Expert and the OEM - RND
Identifying an improvement programme for respective equipment
Target setting and a staircase to develop and/or improve product
Testing and Certification of new developments
Measure Noise – RA
Identify High Noise Emission Machinery
Apply Screening Process

13. Prioritisation of Critical Machines
Factors to Consider
Noise Levels (2024 Milestone)
Other noise factors
Number of persons exposed
Number of machines at work environment
Duration of exposure
Confined space
Machine vibration
Wear parameters
Previous improvement ideas
Effective hearing protection

19. Development Targets Example 2 - Rock Drill
Rock drill noise emissions is a function of the technology, complicated by work environment, and very difficult to influence - Set Targets Accordingly
Approach can be on a SPECIF HPD for Operators or remotely operated RD

20. Conclusions
We can measure NOISE consistently across the mining industry – Understanding the Risk
Value of the Screening Tool:
Lead us to an industry (commodity) specific requirement (Best Achievable Requirement)
Risk based approach
Identification and information on our problematic equipment
Avoid ‘Blanket’ approach on noise management initiatives - Prioritization
Unlock “cheap” Innovation
Assist in maintenance plans – prioritization of critical Noise equipment
