Bell signaling system is commonly being used in underground mines. But this system has its own drawbacks. Therefore, a need exists for improved hoist communications between the skip and the hoist operator. An induction-based communication system using hoist/guide rope as a current carrier can be used for reliable and real-time communication in the shaft. The system transmits and receives energy over a transmission line through hoist/guide rope. Low-frequency transceivers are to be used as transmitting and receiving media. Ferrite current coupler can be used as antenna for the communication. An induction-based hoist communication system has been developed for establishing communication among the mine personnel present at pit top, in moving cage, and at pit bottom. The system consists of a low-frequency electromagnetic wave transceivers unit powered by the external battery and attached with a current coupler clamped with the guide rope, which induces the current throughout the rope (Bandyopadhyay et al., 2002).
