Tom Cawley, Executive Chair, MaxMine, explores how aviation-style ‘black box’ data helps improve safety outcomes, operator behaviour, and overall operational reliability at mining sites.
Flight data recorders, known as ‘black boxes’, have transformed aviation safety since being invented by Australian research scientist Dr David Warren at Melbourne’s Aeronautical Research Laboratory (ARL) in 1954. Black boxes made accidents analysable instead of obscure mysteries. They shifted safety from speculation to evidence-based improvement. Investigators can now accurately identify if human error, mechanical failure, adverse weather, or a combination of factors caused an incident.
Like aviation, mining involves huge, expensive machinery and equipment, where safety is a top concern. Mining incidents cost operators millions of dollars a year. From direct costs such as workers’ compensation to production downtime, equipment damage, and delays, they pose a significant financial risk.
Unfortunately, mining safety is all too often misrepresented as a trade-off against productivity or profit. In reality, safer operations reduce speeding, improve circuit stability, and minimise fleet bunching and digger hang time, while supporting higher machine availability, better tyre lifespan, and reducing damage to machines and roads. Adding trusted driver productivity feedback, average speeds can be increased and cycle times reduced.
Improving safety and cutting costs remains challenging. Most mining safety systems and processes still rely heavily on subjective information, human recollection, and limited physical evidence. By the time a serious incident is reviewed, critical details are often incomplete, contested, or missing. Investigations can appear incomplete and unfair, leading to distrust.
This is why the industry requires a more data-driven safety model. Inspired by aviation, MaxMine has developed a black box-style approach to mining machinery that helps mines investigate critical events objectively and influence safer behaviour before incidents happen.
Using a uniquely high-resolution data recorder, MaxMine’s solution accurately captures the machine, operator, and operating context, enabling key mine teams to go beyond assumptions. This helps identify faults and causes, and often clarifies whether operator behaviour was a contributing factor.
For example, in one case, a young trainee lost control of a fully loaded truck descending a ramp. The investigation found that a water truck had passed seven minutes earlier. The trainee had been driving within the speed limit, but not to the now slippery conditions that required significantly lower speed. This incident became a training opportunity for the whole crew, rather than a potentially disciplinary situation for the driver.
In another incident, a truck ran over a traffic island. Data showed that the driver had fallen asleep. Based on his previous driving data, it was clear that he was normally a very reliable operator, so this was a temporary fatigue issue and not reflective of his usual driving behaviour.
MaxMine has collected data from hundreds of investigations across millions of hours of operations. This creates a uniquely detailed, objective, and meaningful body of evidence about how serious events emerge and how they can be mitigated. By using this reliable, fact-based feedback, MaxMine can influence operator behaviour and reduce risk.
One of the most important lessons from aviation is that flight data recorders are not only important after an accident. Pilots know critical actions are being recorded and that risky behaviour will not disappear into ambiguity after the fact. That knowledge reinforces discipline.
The same principle applies in mining. When operators know that speeding, brake use, gear selection, retarder application, and other risky behaviours are being captured objectively, the safety conversation changes. Feedback becomes more credible. Coaching becomes more specific. Unsafe habits become harder to rationalise away.
One mine implemented MaxMine’s approach in two stages. The first phase saw an 80% improvement in six weeks, which was sustained for a year. The second phase then targeted the elimination of speeding. This was implemented in three weeks and sustained permanently.
The true value of a black-box approach and of using data lies not only in post-incident review. It is shaping behaviour before incidents occur. Just as insights from recorders drove changes in pilot training, maintenance procedures, and safety protocols, the data gathered from mining incidents can drive similar improvements.
By turning individual incidents into systemic learning, accident rates can be significantly reduced while improving accountability and operational standards.
