| Abstract: | To counter the such problems as the low- efficiency of rock breaking and the short service life of the cutters in the process of raise boring operation, carried out a systematic research and has developed a new pick - shaped cutter which is most effective when breaking the hard rocks. Through a comparative study of rockbreaking effects in the real operation between taper- shaped and pick - shaped cutters, proposes the most rational design of cutting structure. Last but not least, the research findings intend to promote the application of raise boring operation. |
