MINING NETWORKS
MST Global ’ s mesh-portable wireless access point is an industry leading intrinsically safe , mobile , self-meshing , network extender and access point . BLE ( Bluetooth Low Energy ) beaconing and receiving BLE broadcasts have now been added to create the mesh
Its advanced feature set enables reliable , highbandwidth , wireless data and voice coverage throughout the mine or tunnel .”
The AXON air + broadcasts as a BLE beacon and MST ’ s FARA workflow management solution uses this information to determine the location of the SMART device that FARA is running on and therefore its location in the mine or tunnel .
The AXON air + also receives BLE broadcasts
from tags and this information is used by MST ’ s geolocation software to locate these BLE tags and their associated personnel and / or equipment in the mine or tunnel .
The AXON air + can be mounted directly onto an AXON core unit or independently to a rock surface . The AXON air + has two PoE + ports that allows it to be daisy-chained eliminating the need for external switches or power supplies . This also enables Wi-Fi and BLE coverage to be extended into hard to get to places without the need for fibre – for example , workshops , declines and the last mile – reducing the overall cost of the solution .
MST Global says both the AXON mesh and air models complement each other and can both be used in addition to the AXON core unit . Eisner said since the introduction of BLE functionality , the AXON products would also work even better with other technologies within the MST Global product family . “ We have a product called FARA , which is a productivity enhancing product which we refer to as ‘ reverse tracking ’ relying on Bluetooth technology ,” Eisner said .
“ By bringing Bluetooth as a comprehensive underlying technology into our AXON stack , it now becomes far more flexible and fluent , so you can use and exchange these devices whichever way you want without losing additional technology . Prior to it , you may have had specialised BLE readers . Now there is one
device that does it all . Our AXON products are a bit like a Swiss army knife of wireless communication .”
Its AXON network infrastructure also comes with the addition of uninterrupted power supply .
“ We normally supply power supply and uninterrupted power supplies ( UPS ) with our systems . The main reason for that is obviously , any IT solutions , particularly if they are safetybased , really need what we call five nines uptime ,” Eisner said .
“ This is also a main feature of these solutions that distinguish us completely from other
technology providers . Power is not easily available underground , there are no sockets or anything around , so it becomes difficult to get hold of power but carrying that through the
same communication cable is a very convenient way of doing it .”

Fibre presents a number of challenges to the underground mining industry . Terminating fibre underground is difficult , time consuming and requires expensive specialised training , which is frequently , the biggest contributing factor limiting the advance of connectivity . These types of delays inhibit the agility and pace needed to enable the digital mine and bring communications to the face .
