Supporting design for hosting beam of auxiliary vertical shaft equipment of Xinzhuang Coal Mine
ZHAO Yu-liang
Abstract：With the increasing depth of coal mining, more and more mines are facing high temperature damage. The drainage pipes in the shaft are affected by the change of temperature, and the force on the hosting beam increases exponentially. New challenges are presented for the supporting of hosting beam. The Xinzhuang Coal Mine has the characteristics such as large shaft depth, high water temperature, large displacement. These characteristics lead to the greater force imposed on hosting beam. But freezing method is adopted during construction stage of auxiliary vertical shaft, no beam nest or back beam nest can be pre-reserved. In the paper, the author focuses on the disadvantages of Xinzhuang Coal Mine, proposes an improved arrangement method of fixing hosting beam with anchor bracket, which improves the strength of anchor bracket and optimizes its structure at the same time, and proposes the force calculation method of anchor bracket.
