If you want to understand underground mining, start with the language. Master the vocabulary, and suddenly the entire workflow from development, blasting cycles, support, haulage starts to make sense.
Tunnels – Often called developments, drives, or drifts. These are the pathways that open up new areas underground.
Face – The business end of a tunnel. This is where the drilling, blasting, and daily progress happens.
Stope – The large chamber created within the ore body during extraction.
Tagboard – The simple but critical system that tracks who goes in and out of the mine.
Shafts – A mine’s main vertical access. People, equipment, and sometimes ore move through it.
Portals – Surface openings that lead underground. They often serve as secondary access or escape routes.
Haulage – Every ton of rock needs to move. Haulage includes rails, conveyors, trucks, or hydraulic systems.
Refuge Chamber – A protected space with its own air supply for emergencies such as fires.
Headings – The zone directly in front of the face.
Charging – Packing drilled holes with explosives like ANFO or emulsions before a blast.
Mucking/Bogging – Cleaning out the broken rock left after blasting.
Unsupported Ground – Freshly blasted rock that needs support—fibercrete, mesh, bolts—before anyone can safely enter.
Stockpile – Where muck is placed temporarily by loaders.
Scaling – Knocking down loose rock using a hydraulic hammer to make the face safe.
Ground Support Materials – Fibercrete, mesh, bolts. These keep the development stable and workers safe.
Dewatering – Pumping out groundwater and runoff so the mine doesn’t flood.
Bogger & Jumbo – A bogger cleans and loads broken rock; a jumbo drills the next round of holes.
Pump Station – Dedicated area for controlling and removing accumulated water.
