Narrow work refers to the driving of restricted underground excavations like drifts, crosscuts, and ventilation airways, as opposed to wide-scale extraction methods like longwall or room-and-pillar mining. This type of development is essential for establishing mine infrastructure, access routes, and airflow circuits. Because the face is confined, narrow work yields less tonnage per blast and often costs more per meter to advance.
Heard on the job
We need to push the narrow work ahead of the main panel so the ventilation circuit is established before production starts.
Do not mix it up with
- Longwall: Narrow work drives tight development tunnels, whereas longwall mining extracts coal across a continuous, very wide face.
