New Smartlight intelligent cap lamps manufactured by mining products supplier PJ Tech can assist in locating trapped miners in emergencies such as rockfalls, says technical manager Peter Nowakowski.
The Smartlight lamps were certified by the Department of Mineral Resources earlier this month as being compliant with the more stringent and new South African National Standard (SANS) 1438 draft legislation, soon to be published.
“This will put us at an advantage as our cap lamps have already been certified and once this SANS standard becomes law mining companies will have 24 months to replace their lamps with compliant lamps,” he says.
The lamp sends a low-frequency signal that will, in conjunction with the MinSearch receiving device, enable rescue teams to determine the distance and direction to trapped miners even through solid rock walls, Nowakowski explains.
The lamp is designed in such a way that 50% of the battery capacity is allocated to the light, with the remaining 50% allocated to the signal. Therefore, even though the battery charge for the light may be depleted sooner, the signal will still be transmitted for six days and nights, he adds.
Further, the light beam can be vertically adjusted and, as one LED light is located on the casing, it will still continue to provide light should the cable be cut or damaged.
PJ Tech also guarantees 1 000 battery charges on the Smartlight, which amounts to more than four years of daily use.
“This is significant, compared with other lamps on the market,” says Nowakowski.
User-friendly stainless steel charging racks add value to the product, he says.
Management software complements the cap lamps, which allows mine staff to gather information about the lamp, such as who it belongs to and how many times it has been charged. Various customised reports are also available.
