Abstract:
The paper stated the technical development course of the mine raise boring construction method, summarized the application conditions of the present r aise boring machine to the underground engineering construction area and had a comparison on the differences between the raise boring shaft drilling technique and th e other drilling technique. The paper pointed out that the raise boring structure could be divided to a main machine, drilling tools and auxiliary system. According to the t echnical features of the raise boring machine, the raise boring method could be divided to a upward remaining method and downward remining method and thus the rai se boring machine could be divided to a upward reaming type and a downward reaming type. On the circumstances, the certain application ideas of the raise boring ma chine were provided from the application to the mine shaft, extended to large non blasting energy saving excavation, underground engineering failure repair, reconstruct ion of the underground engineering in a service period, safety rescue and other area.
