Main Components

This article is studied a coal mine waste rock mine shaft steel headframe which is used more than 20 years and the need of the headframe process transformation. The main components of steel headframe (for example: headframe column, beams and bracing) is sampling inspected the geometry and weld size. At last, SAP2000 is used by analyzing the steel headframe the former and after transformation on the basis of the on-site detection. Field testing and theoretical analysis showed that: the main steel headframe and the envelope structure is largely intact and the only part of the rod local area is a certain degree of corrosion, the connected nodes are basically in line with the requirements of the original design; The steel headframe structure which has transformed and components meet the requirements of national norms.The Identification and reinforcement of the project, will provide a reference for future similar projects.
