论述了矿山反向凿井施工方法技术发展历程,汇总了目前反井钻机在地下工程建设领域的应用情况,对比了反井钻机钻井工艺和其他钻进工艺区别。反井钻井由主机、钻具和辅助系统构成,基于反井钻机工艺特点,将反井钻井方法分类为上扩法和下扩法,相应地研发了上扩式和下扩式2类反井钻机。在此基础上,提出了将反井钻机从井筒应用,拓展到大型非爆破节能开挖、地下工程破坏修复、地下工程服役期改造及安全救援等不同领域。

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.
