The MML is an intrinsically safe tracking and emergency status indicating device tailored for use in mines that do not require two-way voice communications for all miners. It continuously tracks underground miners, allowing them to initiate and receive emergency status warnings. It also provides an audio alert when the MML is out-of-network.

“We are excited to provide this new enhanced capability to our Accolade system,” said Victor Young, vice president of mine solutions, L-3 GSS. “The MML offers an additional means for operators to satisfy mandated safety requirements while reducing overall system costs for new ACCOLADE users.”

The L-3 Accolade system provides a self-healing, redundant and survivable voice and data network, allowing peer-to-peer communication among miners underground and communication between below- and above-ground personnel.
