大直径竖井的无井架施工技术

Non-derrick Construction Technology for Large Diameter Mine Shaft

根据地形特点,大红山铜矿总回风竖井工程采用了无井架施工技术。利用井颈段的钢筋混凝土井壁作为凿井井架,稳绞设备布置具有较好的灵活性,同时减少了钢制凿井井架的设备投入,取得了良好的经济效益。

According to the terrain,the non-derrick construction technology was applied to the total return air shaft of dahongshan copper mine.The upside reinforced concrete was used as a drilling derrick,this technology gained the better flexibility of equipment layout and the less capital input of derrick and the better economic benefit.
