Realizing the disaster caused by mining mishaps could be reduced with effective communication, Australian company Tiller + Tiller, in alliance with Mine Site Technologies, have developed a the Integrated Communications Cap Lamp, a device aimed at ensuring that miners can immediately and easily be contacted with potentially life saving information about emergencies and evacuation routes in the event of accidents underground. The pager uses an ultra low frequency that enables messages to travel through hundreds of meters of rock strata. The cap lamp will flash on receiving a signal and the units will releases a buzzing sound. Messages can be sent to individual units or groups.

The ICCL is the only product of its type available commercially, and has already achieved sales of $3 million annually.
