HazardAvert is a proximity detection and collision avoidance safety system designed to prevent accidents and injuries by detecting when a person or vehicle enters a specifically marked area, or zone, around an operating piece of machinery. When a zone is breached, the system emits an audible and visual warning alert and can be programmed to slow or stop the machine automatically.
With over 1,000 systems currently operating in the global market, HazardAvert is the only system with a proven track record for operating in working sections with multiple pieces of machinery and multiple miners. Every person in the working area is detected by every piece of operating machinery.
HazardAvert can be used in underground coal and hard-rock mines, as well as surface mines. While the core technology is consistent across all types of mining, the system is specifically tailored according to the application and mining type.
HazardAvert creates an electromagnetic marker zone around machinery using field generators. Generators, or Proximity Modules, are fitted onto machinery and create zones designated as the ‘WARNING ZONE’ and ‘HAZARD ZONE’. These marker zones can encompass the entire machine and its turning radius or be specific to certain areas.
Workers wear Personal Alarm Devices (PADs) which detect and measure these magnetic zones and determine their proximity from the machine. For underground coal mining, the PAD attaches to the miners belt and an optional clip-on Warning Module is attached to the hard hat. Underground hard-rock and surface mining PADs and the Warning Modules attach to the hard hat. PADs detect the magnetic fields and emit audible and visual warning alarms.
Zone shaping is accomplished with the use of two or more generators on the same machine. Multiple generators can be used to create tailored zone shapes according to mine management preference. Zones are then standardized for the mine and repeatable across all machinery in that mine. This increases the ease of use and simplifies training.
SILENT ZONES can be created inside the marker field to allow operators to function in specified areas, operator’s cab and close to the machine without activating the alarm or disabling the machine. As soon as an operator exits this silent zone however, they will automatically trigger the system.
Collisions between machinery above and below ground can be prevented with the use of a Vehicle Alarm Device (VAD), integrated into the Proximity Module housing. The VAD detects electromagnetic fields of other machinery and emits warning alarms to the machine operators. Where necessary, the system can be programmed to allow vehicles to interact without nuisance alarms.
The HazardAvert Proximity Ready Kit allows underground coal mines to lay the groundwork for proximity detection, ensuring a quick and final install at a later date. After installing the Proximity Ready Kit, the remaining HazardAvert system components can be quickly and easily installed when the mine is ready.
To capitalize on the wealth of data collected by HazardAvert, Strata has developed HazardLink to deliver safety and productivity data wirelessly to a user interface at the mine surface.
