| Abstract: | Three approaches of shaft construction are introduced. LM-300 raise boring machine is applied according to the actual situation of ventilation shaft project of Shiyashan tunnel. Reasons for the deflection of fully-mechanized raise boring are analyzed. The preventative measures and corrective measures are taken to increase the precision of boring. It is proved that the method improves the construction speed and project quality. |
