Present Status and the Development Orientation of Rapid Mine Construction Technology and Equipment
LIU Zhi-qiang
Abstract：The paper briefly states the mine construction technology in dealing with the complex geo-logical and hydrogeological conditions in recent years in china ,such as ,the developing ground-modifi-cation freezing method ,pre-grouting on the ground technology and their achievements .This paper dis-cusses the development of parallel working of freezing-grouting-shaft sinking ,new type drilling-grou-ting simultaneous operation technology and 1 000m deep mine shaft construction in the aspect of rapid shaft construction technology ,process and equipment.In addition ,it focuses on the new rapid drilling mine construction technology of “one borehole enlargement into one shaft”and the new crafts of large diameter raise boring upward excavation method based on mechanical breaking rocks and reducing un-derground workers.The paper also makes a outlook about the development of shaft construction tech-nology ,and introduces the present research project of mine full face shaft boring machine ,slope along the axis of freezing and non-suspension drilling equipment.
