Glossary of Mining Terms
Methane monitor An electronic instrument often mounted on a piece of mining equipment, that detects and measures the methane content of mine air. Mine development The term employed to designate the operations involved in preparing a mine for ore extraction. These operations include tunneling, sinking, crosscutting, drifting, and raising.
Project Bertha | Mammoet | Heavy lifting
In 2013, the world's largest tunnel boring machine was digging a road tunnel under the city of Seattle as part of a viaduct replacement operation. A major earthquake could put the structure of the viaduct at risk. So the pressure was on to finish the tunnel and commission the viaduct. Early into the tunneling operation, the front end of the drilling machine named 'Bertha' was ...
