Glossary.
Understanding the terminology which miners' use can sometimes be difficult. The songs on this web site include many "Geordie" words which can prove even more difficult for many people. I hope these definitions help in some small way.
Here is just a small sample of mining and Geordie words.


A.
Adit:-Entrance to a mine, usually a drift which sloped from the surface down to a coal seam.
Advanced Head : -A roadway heading which is in front of the coal face line.
Advance Face: -A face where the coal is extracted as the face and roadways advance inbye. Opposite to retreat mining.
AFC:- An armoured flexible conveyor, used to transport coal off a face, coal cutting machines were often mounted above the AFC., Hydraulic chocks were attached to the AFC. so they could be advanced by using a ram.
Airbagging: -A flexible trunking used to conduct air from an auxiliary fan to where it was needed at the head of a driveage
Air Split:- A division of airflow into two or more separate air ways.
Air Way:- Underground roadway or tunnel along which air passes.
Anemometer:- An instrument for measuring the velocity of air in a mine roadway.
Anthracite:- Highest rank of coal of the it has a high carbon content and a low volatile matter. It has a bright black lustre.
Arch Girder:-Also referred to as rings, used to support roadways.
Auger: - A large rotary drill used on a face machine. A screw device penetrates, and breaks the coal. The coal is then loaded and transported via the AFC.
Auxiliary fan:- A fan used in conjunction with air ducting to increase the ventilation to a section of the mine, eg. a development heading or a face heading. Auxiliary fan either sucked the air out (which was replaced by fresher air), or blew air in.

men were on the cage. At other times materials would be sent into the pit via the cage. Coal would also be sent out of the pit (from underground) by the onsetter who was in charge of operations at the pit bottom. The onsetter was the underground equivalent of the banksman.
