AI Technical Summary

Technical Problem

In continuous mining and filling operations in mines, the influx of a large amount of fresh air after the connection of the strip roadway can cause instability in the ventilation system, potentially leading to airflow short circuits, no airflow, or very little airflow. In addition, there is a high risk of gas accumulation and potential explosion hazards.

Method used

Design a wind control device, including a windbreak wall panel, a wind control window, and a windbreak door, which is set at the entrance of a branch roadway. By adjusting the ventilation window and the wind control window, the airflow is controlled to prevent fresh air from rushing in and to ensure sufficient air supply and stable ventilation system.

Benefits of technology

Effectively control airflow to prevent gas accumulation, ensure the stability of the ventilation system, meet the ventilation needs of workers, improve work efficiency, and provide sufficient space for the construction of the retaining wall.
