Intercom system for use in stopes developed Deebar has introduced Winch-Com which it says provides – for the first time – a robust and reliable verbal communication device for use in mining stopes. Currently in stopes, workers have to be in close vicinity to talk to each other or use other means of communication (air whistles) but these signals are often misinterpreted by workers. According to Deebar, the Winch-Com eliminates all

of these problems. Workers can now verbally communicate with each other easily using the system, eliminating miscommunication and resulting in fewer accidents. In case of emergencies – for example, a fall of ground incident – alarms can be rung through theWinch-Com, which will result in a quicker response time to accidents. The new unit is a small and compact version of the tried and tested Wallcomm/Polycom unit, which is extensively used in the mining industry. The Winch-Com is a two-wire intercom system with battery backup. The housing is manufactured in a DMCmaterial which is then fitted in a stainless steel tamper-proof housing with a canopy. It is IP65 rated which means it is protected against the entry of dust and water which makes it suitable for stope environments. The unit is fitted with a built in charger with NiCad batteries, with a standby time of approximately eight hours. The transmit and receive levels are adjustable to eliminate any background noise. An unlimited number of intercoms can be used on a system, which has a tone calling and paging facility and operates using a supply voltage of 525 V AC.
