What is the main goal of using a line brattice in mining?

The primary purpose of a line brattice in mining is to effectively conduct an air current to the working face. This is critical for maintaining proper ventilation in the underground environment, ensuring that fresh air reaches the miners and helps to dilute and disperse any harmful gases, dust, or fumes that may be present.

By directing the airflow towards the working area, the line brattice plays a vital role in enhancing the safety and health of workers by improving air quality and reducing the risk of respiratory issues or exposure to hazardous conditions. Adequate air circulation is essential not only for the comfort of the miners but also for the overall safety measures of the mine.

While line brattices can assist with isolating sections of the mine, supporting the roof structure, or marking safe passages, their main function is specifically to manage and direct airflow to ensure a safe working environment.
