Moving safely around the mine

Collision avoidance systems (CAS), developed for the mining sector by Becker Mining South Africa, prevent fatalities, injuries, damage and downtime that can result from the operation of vehicles in the proximity of personnel, either on the surface or underground.
These modular systems, which range from a simple, low-cost single technology to an integrated multi-technology system, encompass all aspects of advanced mining communications and technology.
Becker’s latest patented tri-technology CAS, with four proximity warning zones, has been designed to overcome the limitations of existing systems and can even bring the mine vehicle to a complete stop should this be necessary.
“This reliable system, which is installed in various mine vehicles and cap lamp battery packs, acts as an early warning indicator to both vehicle operators and pedestrians, playing a vital role in enhancing safety,” says Edwin Bauer, Becker Mining South Africa. “CAS is a very necessary safety system on the mines, particularly underground, because in this harsh environment it is impossible for a vehicle operator always to be fully aware of other miners and vehicles in the immediate area.”
The collision and personnel avoidance systems consist of personnel and vehicle tags and the machine mounted devices which detect them. (Higher end-tags warn personnel of an approaching vehicle). These products may be utilised as a simple standalone or complete system and can be deployed using a phased approach to minimise initial capital outlay.
The new CAS-400 series receiver provides audible voice annunciation (customisable in different languages) and visual warning proportional to the position of the threat. An onboard buffer enables authorised personnel to download daily movement details, either physically, or via a wireless network like a leaky feeder system.
Miners are cautioned when they get too close to a vehicle by means of a flashing light and buzzer on the cap lamp. The number of flashes, which is limited to five, indicates the number of vehicles in a miner’s vicinity. The detecting range can be set according to specific requirements. The combination warns personnel of machines, machines of personnel and machines of other machines. A further advantage of the new multiple technology approach is that mines now have the flexibility to monitor both slow and fast moving equipment on the surface and underground using one system.
