One of the biggest risks to safety in a mining operation is the interactions between mobile assets and personnel. The risk exposure in this area is significant, as vehicles and people continually utilise the same working spaces – intrinsically hazardous environments in which reduced visibility and changes to the operating context are the norm.
SAFEDETECT™ addresses these risks by providing vehicle operators the ability to detect the presence of nearby personnel and vehicles through a high precision proximity detection system (PDS), giving contextual awareness and warning of proximity hazards well before a threat is posed – even when clear line of site is restricted.
SAFEDETECT™ operation is enabled by an advanced sensor technology – WASP – developed by the Australian CSIRO. The technology’s capability is derived from ‘time of arrival’ calculations of high frequency radio waves, providing an accurate distance range to other WASP sensors. With the use of this technology, SAFEDETECT™ can operate independent of other forms of communication networks and provides one of the most accurate detection capabilities available to the market today.

A case for proximity detection
Serious personal injuries as a result of mine vehicle interactions are a well known reality for mine operators. Despite significant efforts to solidify workplace controls and the advances in proximity technologies for heavy equipment, vehicle collisions and near miss interactions are still occurring at alarming rates.
Fatigue and restricted vision are often identified as the root causes of serious vehicle incidents. Evidently however, control measures tend to bias reducing fatigue rather than controlling vision or the physical characteristics of equipment.
Considerations in vehicle interactions that are sighted but relegated in actionable priority include; the conditions of the roads, intersections, the line of sight of the driver, the restricted vision of the vehicle, windrow height and fit for purpose signage.
With the limited probability of organisations altering the physical dimensions of on-site vehicles, proximity detection , collision avoidance technologies and simple administrative controls can provide the appropriate mechanism for restricted visibility circumstances – helping to alert operators of imminent interactions and the need for evasive action.
