The disc-type rock tunnel boring machine integrates functions of excavation, support, anchoring, transportation, probing, and mobility. It offers advantages of high construction efficiency, reduced personnel requirements, and excellent maneuverability. Capable of excavating hard rock with uniaxial compressive strength of 60–150MPa, it achieves a maximum excavation rate of 15m³/h and can adapt to hard rock tunneling in any cross-sectional shape required by the customer.
