Abstract：In order to solve the loading capacity of the approved type shaft sinking headframe,the geometry size and others hard to meet the present deep and large diameter mine shaft construction requirements,a new mine shaft sinking headframe suitable to the mine shaft with a diameter of 8 ～ 12 m and a depth of 1 200 m was researched and developed.The paper systematically introduced the design idea,structure features and major technical features of the new mine shaft sinking headframe with a single platform.The new mine shaft sinking headframe optimized and innovated the sheave wheel platform and support system structure,including two series (a single platform and double platform),each with three specifications (suitable for the mine shaft with a diameter of ＜8 m,8 ～ 10 m and 10～ 12 m.The headframe could set 4 sets of the hoisting equipments at the same time and in maximum and the max suspended loading could be over 10 000 kN.The researched and developed SA-3 type mine shaft sinking headframe with a single platform was applied to a mine shaft engineering of a mine auxiliary shaft in Benxi Sishanling Mine in China and under the actual performances,the stress monitoring and measuring of the mine shaft sinking headframe were conducted.The results showed that the new mine shaft sinking headframe would have the reliable loading performances the construction suitability.The mine shaft sinking equipment would have more large spacing to set up the equipment,the layout mode would be more flexible and thus the safety and high efficient construction of the deep and large diameter mine shaft could be effectively ensured.
