[0002] In coal mines, in order to protect the normal progress of underground operations, some shafts need to prevent airflow from flowing through them. To prevent the incorrect airflow from affecting the safety of normal underground operations, it is usually necessary to use a damper in conjunction with a locking device to control the closure of the damper.
