Mechanical equipment for underground engineering refers to various mechanical devices specifically designed for the development and construction of underground spaces. These devices include tunnel boring machines, shield machines, wet – shotcrete manipulators, rock bolters, and many other types. They play a crucial role in projects such as the construction of highway and railway tunnels, subway projects, mine roadway excavation, and underground cavern development.

Tunnel boring machines and shield machines can efficiently excavate underground passages. Through advanced cutting and support technologies, they ensure the safety and stability of construction. Wet – shotcrete manipulators are used to spray concrete, supporting the tunnel walls after excavation, preventing the collapse of surrounding rocks, and enhancing the durability of the structure. Rock bolters are used to drill holes in the surrounding rocks and install rock bolts, further reinforcing the underground structure.

The continuous development and innovation of mechanical equipment for underground engineering have improved the construction efficiency of underground projects, reduced construction risks, and propelled the development and utilization of underground spaces to new heights.
