1. Cantilever roadheader can cut part of the cross-section, to break the whole section of rock, need to repeatedly move up and down around the cutting head to complete the work. Can be used for any cross-sectional shape of the tunnel.
2. The driving speed of Cantilever roadheader is greatly affected by the utilization ratio of the boring machine, and the utilization ratio is about 60% under the optimum condition. But if the rock needs supporting or other auxiliary work can not keep up, its utilization rate is lower.
3. Same advantages as full-face TBM: continuous excavation, no blasting vibration, more freedom to determine the right time to support the rock; can reduce over-excavation; can save the cost of rock support and lining.
4. Compared with the full-face TBM, cantilever roadheader compact, in the tunnel have greater flexibility, can be used for any type of support.

5. Compared with the full-face TBM, with less investment, short construction time and re-use of high salient features.
