What Is Bratticing? Ventilation Control in Underground Mines
Definition
Bratticing is the practice of hanging fire-resistant cloth (brattice cloth) in underground mines to control and direct airflow.
Key Functions
- Ventilation Control: Creates temporary or permanent air channels to deliver fresh air to work areas and remove hazardous gases, dust, and fumes.
- Safety Enhancement: Prevents accumulation of flammable gases like methane and carbon monoxide.
- Sealing & Leakage Control: Isolates sections to prevent air short-circuiting and ensure efficient use of ventilation resources.
- Circuit Formation: Allows multiple ventilation circuits for targeted air distribution.
Materials
Brattice cloth is made from non-combustible, tear-resistant materials such as fiberglass, PVC, or flame-resistant fabrics that withstand harsh underground conditions.
Applications
Used both as temporary measures during construction/maintenance and as permanent installations in specific mine sections.
Monitoring
Regular inspections are critical to detect damage, tears, or improper installation that could compromise airflow and safety.
