• A large test area is needed. It is important that the test vehicle is at the intended speed well
before the first control level will be triggered, hence appropriate run-up is needed.
• It is important that the CMS distances are known before starting the test. This includes
understanding the intervention strategy the CMS will apply.
• Controlling the speed at the intended speed is important to ensure accurate performance
of the CMS.
• Communication between the drivers of the two test vehicles is of vital importance.
• CMS suppliers often have not discussed the expected system performance with their customers (the mine). This complicates matters, as CMS suppliers often are not mining experts
with limited exposure to the day-to-day operations of a mine. Very often there is very little
guidance from the customer to guide and influence the development of the CMS.
• The test report must be written for a non-technical audience, failure to do so may result in
readers questioning the veracity of the report.
Feedback from the CMS suppliers after conducting tests have been positive, with the following a summary of the feedback:
• The testing is extremely thorough;
• CMS suppliers have underestimated the complexity involved;
• Tests have contributed significantly to improving the offerings of CMS suppliers; and
• The evaluation procedure has provided a better understanding of the environment within
which CMSs will be used.
5 CONCLUSION
An evaluation procedure was developed in cooperation with the MINCOSA which thoroughly tests the performance of CMSs. This evaluation procedure has been found to be a
game-changer in the development process to improve technology readiness levels.
