[0036] Mining and tunneling are two very important links in the coal mine production process. Among them, the efficiency of tunneling is lower than the efficiency of coal mining. Therefore, improving the efficiency of tunneling has become the current focus of coal mine work.

[0037] When a tunnel is first excavated and before bolting, the surrounding rock is often unstable, and the top working surface is prone to collapse, posing a significant safety hazard to excavation equipment and personnel. Therefore, a temporary support device is required to protect the top working surface before bolting is implemented.

[0038] However, due to the presence of other devices on the tunneling equipment and the influence of spatial layout, the protection area of ​​traditional temporary support devices is relatively small, and some working faces will be missed and fail to achieve effective support.
