What is a line brattice?

A line brattice is correctly identified as a curtain erected from the last crosscut to the face. This essential component of underground mining serves to control airflow within the mine, ensuring that fresh air reaches the working face where miners are operating. By creating this barrier, a line brattice helps effectively direct ventilation to dilute and remove harmful gases, dust, and other potential pollutants from the miners' working environment.

The strategic placement of a line brattice can significantly improve air quality and maintain safe working conditions, which is vital in the complex and often hazardous environment of an underground mine. Additionally, it helps in maintaining a clear separation between different airflow pathways, allowing for better management of ventilation systems.
