Strata Worldwide has released the StrataConnect™ second-generation miner communicator (MC2) as it looks to improve communication with and tracking of personnel in underground mines and tunnelling sites.

The MC2 device operates on the underground StrataConnect wireless mesh network, formally known as Strata CommTrac.

Strata said: “Designed specifically for the harsh environments in the mining and tunnelling industries, the Strata MC2 provides two-way text communications, real-time personnel location tracking and both critical alerts and response functions for workers.

“Its comprehensive physical redesign and enhancements were geared towards simplifying usability and expanding device functionality.”

Modeled after today’s smartphones, the MC2 has a full, hard-button QWERTY keyboard, a large display screen with multiple character sizes, and an easy-to-navigate operating system, according to Strata.

Its features include one-on-one or group text messaging, the ability to access a full, automatically updating contact list, data storage for up to 500 messages and a rechargeable battery that lasts through multiple shifts. MC2 also provides critical alerts and response capabilities for workers in the event of an emergency, has an audible alarm that ensures miners know when a message has been received and comes equipped with clearly distinguishable emergency messages that allows miners to easily respond with their condition, the company said.
