Abstract: According to the various design Institute and the hositing headframe used Mine on the impact of differential settlement of foundation on headframe feedback，In the course of revision of “Code for design of the mine headframes”, the organizations concernded carried out special studies on the impact of steel headframe. Through analyzing the causes of differential settlement，study of differential settlement influence on internal force and deformation of different headframes type, the rationality of “Code for design of the mine headframes” GB50385-2006 is discussed, and put forward amendments.
