[0002] Roadway is the throat of coal production, and is the channel for ventilation, drainage and transportation of coal mining. Coal mine roadway support refers to reinforcing and protecting coal mine roadway to ensure the safety of construction personnel. In the process of roadway driving, roadway support is a very important work, which not only relates to the safety of construction personnel, but also directly affects the efficiency and quality of coal production. However, due to the complexity of coal mine geological conditions, coal mine roadway is prone to roof subsidence and roof fall, which often poses a great threat to the safety of construction personnel. In particular, the newly exposed roof of the driving roadway is in an unsupported state, which is more dangerous. Therefore, temporary support of coal mine driving roadway can effectively control and prevent roof fall and other safety accidents.

Therefore, improving the reliability and safety of roof support technology and realizing the belt pressure jib moving of track self-moving temporary support device are crucial for ensuring the safety of construction personnel on site.
