摘　　要：提升井塔承担着矿井生产的人员升降、设备运送、矿产资源提升等任务,是矿井生产的重要构筑物。目前国内井塔的结构型式多以钢筋混凝土结构为主,其刚度大、承载力高,但缺点是自重大、施工周期长、占用井口时间长,钢结构井塔自重轻,抗震性能好,具有很好的应用前景。根据井塔的工艺要求、功能特点,结合钢结构的受力特性,从结构的平面和竖向布置、抗侧力体系构造等方面分析了钢结构井塔的结构体系,包括钢框架-支撑体系、巨型钢框架体系、桁架筒体体系,阐述了各体系的优点和存在的问题。重点对钢框架-支撑体系进行了计算分析,为钢结构井塔的设计提供参考。Hoisting headframe is a critical structure for underground mine production,which lifts the personnel,equipment and mineral resources.In China,reinforced concrete structure is the most common structural type of headframes,which has high stiffness and bearing capacity,large dead load and long construction cycle,while the steel structure headframe makes up for it shortcomings with smaller dead load and anti-seismic property.According to the technical and functional requirements of headframe,as well as the stress characteristics of steel structure,the structural systems of steel structure headframe,namely the braced steel frame system,large scale steel frame system,and trussed tube system are analyzed,from plane and vertical layout,and the lateral force resistance.The pros and cons of each system are expounded.Finally,the calculation of the braced steel frame system is carried out.
