The invention belongs to the field of mine capital construction, and particularly discloses a construction method of a large-section variable-diameter ore storage bin formwork support. The construction method is convenient for construction of the large-section variable-diameter ore storage bin formwork support. The construction method is easy to operate and convenient to construct, and scaffold components and accessories needing to be used can be conveniently fed into an ore storage bin to erect a scaffold by reserving a material lowering space in a central area in the ore storage bin; vertical rods, bottom horizontal tubes, horizontal rods and diagonal bridging are sequentially erected on an ore storage bin erecting site, the longitudinal and transverse distance between the vertical rods and the layer height of the erected horizontal rods are effectively controlled, the stability of the scaffold is guaranteed, the construction load is reduced to the maximum extent, and safety and reliability are achieved; by arranging a personnel up-and-down passage, the convenience of construction is improved by facilitating up-and-down passage of personnel; by hanging a mounting net, the construction safety is further improved.

本发明属于矿山基建领域，具体公开了一种大断面变径型矿仓支模架的施工方法，该施工方法便于对大断面变径型矿仓的支模架进行施工。该施工方法操作简单、施工方便，通过在矿仓内部中央区域预留材料下放空间，便于将需要用到的脚手架构配件送入矿仓内部搭设脚手架；通过在矿仓搭设场地依次搭设立杆、扫地杆、水平杆和剪刀撑，并有效控制立杆间的纵横向间距及搭设水平杆的层高，保证了脚手架的稳定性，最大限度地降低了施工荷载，安全可靠；通过设置人员上下通道，利用人员上下通行，提高了施工的便利性；通过挂设安装网，进一步提高了施工的安全性。
