1. UKHOZI – RTF 15 September 2017 Trackless Mobile : PDS ASPASA’s Work
Nico Pienaar
Director
ASPASA

2. Background
The mining industry in SA has had incidents with fatalaties where employees were involved.
The Quarry Industry has had very few incidents.
The Legislation was developed for all mining
The affect to the surface and quarry industry is substantial as costs, practical implementation and supplier commitment was a challenge for the industry.
Service providers of PDS systems all pounced on the industry with very good marketing presentations
ASPASA was becoming aware that:
* There was a lack of field testing and research.
* No proof of reliability
* No proof of effectiveness
* Some success in underground mining but surface mining not conclusive
* OEM’s of machines need to fit these when selling

3. Background ASPASA demands that: * Systems be reliable
* Tests to be on actual mining equipment while working
* Vibration and signals to be adverse to affecting a system
* Real objects need to be detected
* Serious common sense needs to prevail
* Focus to be given to:
Blind Spots
Collision Warning System to be reliable
Sensors to withstand conditions
Alarm display
False alarms
Reliable Detection Zones
Sporadic Detection Zones
Zone Depths
* Proper Risk Assessment to be done per operation
* Vehicle separation

4. Some Concerns ASPASA has had to deal with
The OEM’s apparently are not too concerned in developing systems and if they have a system it is not affordable for most operations
Not all industry role players seem to understand the implications and we find that attempts are being made to do Risk Assessments to prove systems are not needed. This might work in a small number of operations.
ASPASA served on an MRAC sub-committee who investigated the issue and it seems clear there is a serious lack of understanding of the complexity of the solutions from the PDS suppliers.
There, it seems, is a wait and see strategy in industry
Because there is uncertainty, costs and system wise, companies are not budgeting for such a system or implementation
Test sites and lack thereof is allowing “fly-by-nights”, to pounce on the industry, at huge costs for the industry

7. ASPASA “Safer by ……” Initiatives
Safer by Competence
Employees
Contractors
Safer by Design
Safer by Sharing
Safer by Partnership
Safer by Association
Voluntary guidance addressing the design vacuum that exists between many Manufacturers and Users of heavy mobile plant
Aspasa Seminars giving H & S guidance to members by sharing good practice; Peer-to-peer assistance
Package of Aspasa measures designed with contractors focusing on CONTRACTOR SAFETY.
Site audit by Aspasa aimed primarily for the benefit of its members.

8. The Narrow Margin for Safety

9. Chapter 8 Amendments
…. Where there is a significant risk of such collisions…
Trackless mobile equipment must be provided with means:
… to automatically detect the presence of pedestrians in UG, and equipment in Pits, to effectively warn the operator of such a presence
“Collision Awareness” should already be implemented
And in the event where no action is taken to prevent potential collision, further means shall be provided to retard the “trackless mobile machine” to a safe speed where after the brakes of the diesel powered “trackless mobile machine” are automatically applied
“Collision Avoidance” with a period of grace till technology is available.
This communication addresses the following:
Identification of ‘significant risk’
The period of grace for active Collision Avoidance
The requirements by Industry to satisfy that relaxation on the period of grade
* Way Forward
4. Coordinating and monitoring progress.

10. Chapter 8 Amendments
…. Where there is a significant risk of such collisions…
“Significant Risk” to be determined by each site through a risk assessment process
Only equipment with significant risk need to have PDS technologies fitted
“Minimum requirements” for equipment where there is significant risk
Underground : at least equipment to Pedestrian PDS technologies
Opencast and Pits: equipment to equipment PDS technologies
Otherwise reasonably practicable controls to reduce the risk from significant
Where no risk assessments have been completed all equipment may be required to be fitted with PDS technologies

12. Technology Development Process for PDS and OEMs – Level 8 & 9

13. What has APSASA done? ASPASA Contracted:
Thys Greyvenstein who has been in the mining industry for 36 years – worked for Anglo American. Drover collision management before he retired.
Dr. Chris Doran (Mining Technology Consultant) is an independent consultant to the Mining industry with over 25 years of experience. Has worked on collision awareness and avoidance space. Is representative of EMESRT working on new ISO Collision awareness and avoidance standard, being developed.
Spent 4 ½ days in workshop with the industry specialists – using DMR figures, plus quarry updated figures.
ASPASA has summarized and shared with industry the following:

And in the event where no action is taken to prevent potential collision, further means shall be provided to retard the “trackless mobile machine” to a safe speed where after the brakes of the diesel powered “trackless mobile machine” are automatically applied
Compromise on Collision Avoidance:
UG Electrical – now. Technology already available
UG Diesel – new equipment purchased after June 2017, but be CA ready
UG Diesel – June 2018
Opencast and Open Pits – June 2019
Surface (plants, concentrator, quarries, services, etc.) – June 2019
Grandfather clause – December 2019

20. Conclusion Some focus areas: Traffic Management Plans must be in place
Speed needs to be controlled
Focus on workshops
Drivers must be trained on PDS – don’t put systems in and not understand – why/what?
Mine layout and traffic management needs to be evaluated.
