Emergency Messaging

Emergency Messaging in Underground Coal Mining

Emergency Evacuation

The safety of personnel during an emergency depends on the ability to easily and quickly communicate evacuation instructions. At the time of an incident, personnel may be located in an area underground where communications or power infrastructure has been cut-off or may not exist at all. This leaves personnel either unaware of impending danger or without clear instructions on what to do and which evacuation route to use.

Solution

MST’s through-the-earth (TTE) communication uses an ultra-low frequency transmission that propagates through rock strata to provide text messages to personnel regardless of their location underground. The text message receiver known as the PED® (Personal Emergency Device) integrates into the miners cap lamp battery to ensure easy adoption. Primarily used to quickly and safely evacuate personnel, it can also issue work instructions for the deployment of personnel and equipment.
