Review on development of mine shaft construction technology

The paper reviewed four shaft sinking technology development stages,including the mine shaft construction with the small equipment and a research and de velopment program on the mechanized matching of the mine shaft construction equipment,research and development on mechanical matching technalogy conducted by the Ministry of Coal Industry,Ministry of Metallurgical Industry and First Ministry of Machinery Industry,the research and development on the construction matching equipment 0 f the mine shaft short section lining combined operation,the research and development on the sinking technology of the 1 000 m mine deep shaft. The paper fully introduce d the mechanization and matching construction equipment of the mine shaft construction and stated the hoisting system,winch suspension,borehole drilling and blasting,roc k loading equipment and mine shaft lining formwork conditions. At present,a short section excavation and lining combined operation construction method with an excavatio n and lining normal circulation was fully conducted. The average mine shaft completed speed was over 80 m permonth. A technology and equipment research and develop ment of mine shaft excavator,a research and development on the shaft sinking equipment of the large diameter mine deep shaft,the key technology and equipment of the e xcavation,lining and installation operation for the 1 000 m deep mine shaft and the research orientation were provided. Meanwhile,a prospect was conducted on the develo pment tendency of shaft sinking technology for future deep mine shaft.
