根据多年来我国立井凿井井架的设计实践,采用空间有限元分析方法进行了新型双平台立井凿井井架研发,系统分析了井架主体结构选型、施工荷载计算和结构验算等内容。研发的双平台系列凿井井架可满足最大净直径12 m、深度1 200 m条件的立井井筒施工,最多可同时布置4套提升装置,极限悬吊荷重10 000 k N以上。新型双平台凿井井架已在我国大海则煤矿1号副井(井筒直径10m、深度660 m)井筒工程中应用,采用上层提升平台与下层悬吊平台结构形式,设备布置空间更大、布置方式更加灵活;同时有效降低了井架重心高度,有利于整体稳定。新型双平台井架在大海则煤矿1号副井的成功应用,验证了井架设计方法的正确性。

According to many years design practices on the sinking headframe of the mine shaft in China, a space finite element analysis method was applied to th e research and development on the new double platform sinking headframe of the mine shaft. The paper systematically analyzed the selection on the main structure of t he headframe, the calculation on the construction load, structure checking calculation and other contents. The research and development on the double platform series sinking headframe could meet the construction of the mine shaft with a max net diameter of 12 m and a depth of 1 200 m and maximally the headframe could arrange fo ur sets of the hoists simultaneously. Each hoist could have a limit suspension load over 10 000 k N. The new double platform sinking headframe was applied to the min e shaft engineering of No. 1 Mine Auxiliary Shaft ( the mine shaft diameter of 10 m and a depth of 660 m) in Dahaize Mine, China. The function of the upper hoisting pla tform and the low suspension platform could be divided, thus the equipment layout space could be larger and the layout mode could be more flexible. Meanwhile, the he ight of headframe gravitational center could be effectively reduced and would be favorable to the integration stability. The successful research and development as well as the application of the new double platform sinking headframe verified the accuracy of the headframe design method.
