Voice Communications in Underground Hard Rock Mining

Voice Communication is a fundamental element of productivity and safety in mining and MST offers two main solutions:

  • Leaky Feeder Radio for underground mines and tunnels.
  • Voice over Internet Protocol (VoIP) technology.

MST’s VDV Leaky Feeder technology is widely used, with radios from Motorola, Tait, and others,  but with more digital networks being installed in underground mines the use of our VoIP MinePhones is growing.  Sometimes starting with our MP71 MinePhone being used to complement an existing leaky feeder radio system, with the VoIP MinePhones  providing private communications between personnel.

Benefits of VoIP

Emergency MessagingUsers can make and receive person-to-person VoIP phone calls to communicate safety, production or technical information and instructions. This capability can be between personnel underground and between underground mine personnel and personnel anywhere around the world. The technology does not have the limitation experienced by two-way radio of a finite number of channels, and so facilitates any number of person-to-person calls at the same time.

However it still offers Push to Talk (PTT) functionality like standard radio system for group calls on up to 24 channels. Plus, unlike traditional radio systems, it does not require frequency licensing, as it uses the free 2.4 GHz Wi-Fi band.

Additionally, the MinePhone acts like a RFID tag, in that a MinePhones proximity to  underground access points allows it’s location to be determined, and so enables personnel tracking in underground mines for the purpose of safety and productivity. Additionally, the MinePhone can remotely access the tracking data on the central server and undertake searches for assets or people.
