[0002] Support is a set of measures used to reinforce and protect the sidewalls and surrounding environment to ensure the safety of underground structure construction and the surrounding environment of the foundation pit. During coal mine excavation, coal slag or rocks may fall from the tunnel ceiling, requiring support to prop up the tunnel. The support methods used in tunnels are generally divided into shotcrete support, shotcrete support, anchor bolt support, metal mesh support, and steel arch support. To ensure tunnel excavation efficiency while providing support, steel arch support is usually used.
