Smart Marker System:  The New Tool
for Measuring Flow in Mass Mines

Elexon Electronics is proud to introduce the Smart Marker System – the world’s only automated tool for measuring underground ore flow in Sub Level and Block Cave mines.

Developed at the request of the Mass Mining Technology (MMT) project, the Smart Marker System simplifies the process of carrying out marker trials and delivers underground ore flow data at a level of resolution never available before.

What are Smart Markers?

Smart Markers are blast resistant, long-life Radio Frequency Identification (RFID) devices that are placed in the ore body of Sub Level or Block Cave mines. The Smart Marker System automatically detects, logs and time stamps Smart Markers as they are extracted with ore at the production level. It collates installation and extraction data in real time.


By knowing the original installation position of each Smart Marker, along with the time and location of  its extraction, the movement of rock in an underground ore body can be analysed, revealing flow over time.
