Discussions on key points for structure design of steel headframe in coal mine
LIU Kuang
Abstract：Steel headframes are widely used in vertical lifting in large and medium-sized coal mines due to the excellent structural performance.In order to study the layout selection,stress analysis,load combination and other design points of the design of the four inclined column steel derrick,an actual project was taken as an example,the same model was calculated using the partial coefficients of different specifications,and the results were compared.The results indicate that designing according to the new standard's sub coefficients is safer and can be used as a reference for similar projects.At the same time,suggestions were put forward to attach importance to the preliminary scheme design,and to carry out parametric and modular design.
