Development status and prospect of mine raise boring technology and equipment
Liu Zhiqiang
Abstract:The paper stated the technical development course of the mine raise boring construction method,summarized the application conditions of the present raise boring machine to the underground engineering construction area and had a comparison on the differences between the raise boring shaft drilling technique and the 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 technical 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 raise 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 machine were provided from the application to the mine shaft,extended to large non blasting energy saving excavation,underground engineering failure repair,reconstruction of the underground engineering in a service period,safety rescue and other area.
