Analyses of the Extreme Allowed Depth of Standard Sinking Shaft Headframe and Optimal Design of its Construction Members
Sinking shaft headframe is the main installation above the ground during the sinking shaft excavating period.Current stan-dard atlas was formed in 1986.After more than 30 years development of mining industry,there are so many differences between stan-dard atlas and design code or conventional process.Depending on the project with 1 300 metres sinking shaft in Yantai of Shandong province,the synchronous-incompatible relationship between the loads was sorted out.According to current design code,the ex-treme allowed depth of standard sinking shaft headframe was figured out.The stress ratio was calculated respectively by using the hoisting load and broken rope load,then the main reason why the standard headframe have more allowed depth was found out.Ac-cording to the demands to solve the problem of producer,spatial models was adopted to optimize the members of headframe.
