The Problem
A recent incident report identified a “Near Miss” at an underpass intersection between the 2nd main travel routes of the mine, involving a loader and a man transporter. Safety meetings with crews identified that with the LED strip lighting underground, it made it difficult to identify vehicles entering the main headings from blind corners, and suggestions were made to remove strip lighting from around the underpass intersections to allow identification of vehicles at the intersection (via headlights on the vehicles).
The Solution
After further consultation, it was decided not to remove the current lighting from the intersection but to find a solution that would work within all the current controls under the Mine Transport Rules. Work was already being trialled on using coloured LED indication for belt monitoring purposes, and testing began on using the same string of LED to use an amber light to give an indication of movement from around the blind corner. An ultrasonic system was chosen, as a way of removing human behaviour, and testing to confirm functionality, so that either vehicle or pedestrian would activate the warning lights. A trial was put in place at 30ct underpass to test overall functionality and allow feedback from the workforce as to what changes were required prior to implementing through out the mine.
Benefits/Effects
By adding an autonomous warning system, it gives a visual warning to vehicles/pedestrians in the travel roads of movement around the blind corner. Being autonomous, there is no reliance on people’s behaviours or attitude.
Transferability
Already looking at using the same system to change existing block lights on site to ultrasonic, replacing existing drift lighting with the same LED strips, use of LED strips to indicate gas levels at TG machine doors.
Innovation
Combined current technologies to achieve working system.
Approximate Cost – $2600 for single control box and lighting

Exoskeletons, or wearable robotics, are appearing in scientific journals, industry publications, the media, and even in some workplaces as a potential ‘solution’ for workplace musculoskeletal injury prevention.
This presentation will outline the different types of exoskeletons currently available and their intended uses, including how they can potentially reduce the load on specific muscle groups to minimise fatigue and subsequent injury. However, there are also several documented risks associated with their use in industry. A review of the current evidence base will be presented.
Acceptance of exoskeletons across industries and different work types has been variable and is still in relatively early stages of development and implementation. Mining is often seen at the forefront of safety innovation and can be early adopters of new technologies and processes. Could ‘Exos’ be the next big thing for our industry?
To assist potential users and purchasers to make informed decisions before trial or purchase of such devices, a checklist for independent evaluation will be presented. This takeaway resource will also outline a number of ‘toolspecific’ risk factors to be considered in any onsite formal pre-use / pre-purchase risk assessment for the mining environment.

Tragically Saraji Mine had a fatality on New Year’s Eve 2018 involving a bulldozer rolling down an embankment. The first responders to this incident required the use of heavy duty slings and shackles to upright the dozer. This involved personnel traversing down a steep embankment on undulated ground during the night carrying D-shackles that weighed approximately 62kg each, this created a significant manual handling risks to the people involved.
Post incident, Saraji became aware of light weight synthetic couplings that are made specifically for the marine industry that significantly reduced the weight whilst providing exceptional strength properties.
We reached out to the manufacture of the light weight synthetic couplings in New Zealand in an attempt to replicate this technology within the mining industry. By substituting the existing steel D-shackle with a custom made light weight synthetic design, we have reduced the potential of a manual handling incident when recovering surface mobile equipment or the potential for stored energy within the steel to become airborne should the steel D-shackle capacity be exceeded.
The soft couplings were tested to 175,000 kg for a maximum breaking force (MBF) of 510,000 kg without breakage and have a total weight of 8.2 kg compared to the 62 kg steel D-shackles that are normally used.
The synthetic couplings have been successfully trialled on site to extract various pieces of surface mobile equipment. They have been included as mandatory items in the emergency equipment recovery trailer along with other items to aid in the immediate recovery should the need arise.

Fatigue is a vital health and safety issue in the mining industry with a multitude of medical and organisational causes and implications.
This presentation will focus on the nature of circadian rhythms and how they can contribute to fatigue. The ways in which shift work can impact these matters is specifically considered, given the relevance of varied work and shift patterns to the mining industry.
The physiological effects of fatigue will also be discussed, including how these can translate into performance-based effects.
The presentation will also consider the complex interactions between the multiple medical, social and employment factors which contribute to fatigue.
