The cut-and-advance tunneling drilling rig adopts a three-arm combination design featuring dual advance booms + cut boom, enabling synchronous and coordinated operation for cutting and advancing. Blast holes and cut holes are completed simultaneously, saving more than 20% of rock drilling time. Advance blast holes reach a depth of 6m, while cut holes reach 6.3m, achievable in a single pass, with single-cycle advance footage exceeding 5.5m.

Technical Features

Deep Single-pass Drilling Depth

Adopts a composite extended propulsion design, allowing rock drilling blast hole depths up to 6m.

Wide Operating Range

Employs a dual-propulsion design for broad coverage of the working face cross-section.

Coordinated Cutting and Rock Drilling Operation

Three booms with independent control enable synchronous and coordinated operation for cutting and advancing.
