Networked Smart Markers are a robust and reliable alternative to Time Domain Reflectometers for measuring the location of the Cave Back.
Understanding the cave back position is critical for managing the propagation of the sublevel cave until it breaks through. The risks of uncontrolled caving include air blast, resource sterilisation and excessive waste ingress.
Networked Smart Markers use Smart Marker technology, with a long battery powered lifespan. Data communication is based on through-ground radio transmission which eliminates risk of system failure through cables broken by moving ground.
