Rock Flow System
CONTINUOUS HARD ROCK HAULAGE SYSTEM

Block Caving with Continuous Haulage
Block cave mining is a mass-mining technique used in many underground
mines around the world. The innovative Cat® Rock Flow System – jointly
developed with the Chilean mining company Codelco – greatly improves
productivity by making use of continuous haulage technology as compared
to the conventional use of LHD’s.
The Cat Rock Flow System combines the usage of a Rock Feeder,
a Rock Mover and an automation system to deliver mass mining
production with improved safety and sustainability.

The Rock Feeder RF300 extracts ore from the drawpoint onto the
Rock Mover (Hard Rock Chain Conveyor) by a hydraulically operated
push plate. The Rock Mover RM900 is a dedicated hard rock production
conveyor that collects ore from various drawpoints. An automation
system (featuring remote operation from surface) allows draw and
quality control and records operational data.
