Abstract：In Sanxin Gold and Copper Mine ,a new mine shaft has a depth of 1 091m and a net diameter of 4.5m.A hydraulic umbrella drilling frame for rock drilling ,a central rotary grab for rock loading , 3.8m height integrated metal formwork for the shaft liner and other large mechanized matched opera-tion line were applied to the construction of the mine shaft .The new headframe of the mine main shaft is a cast-in-site reinforced concrete frame and a shear wall structure and was constructed with sliding formwork technology.The mine shaft and headframe were constructed in parallel .The total construc-tion period of the mine shaft and headframe could be reduced by seven months as predicted.Obvious economic benefit would be obtained.The technology successfully applied to the construction of the 1 000m depth mine shaft could promote the technology innovation of the mine construction sector in China ,would drive the upgrading of the integrated technology level in China mine industry and would promote the industrial technology progress.
