New mine shaft sinking headframe with single platform applied to construction of deep and large diameter mine shaft

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 lar ge diameter mine shaft construction requirements, a new mine shaft sinking headframe suitable to the mine shaft with a diameter of8~ 12 m and a depth of 1 200 m w as researched and developed. The paper systematically introduced the design idea, structure features and major technical features of the new mine shaft sinking headfr ame with a single platform. The new mine shaft sinking headframe optimized and innovated the sheave wheel platform and support system structure, including two serie s ( a single platform and double platform) ，each with three specifications ( suitable for the mine shaft with a diameter of
