| Abstract: | The values and developing laws of frozen pressure have been measured by steel string transducer in Dongyong mining district.The testing results state clearly that the frozen pressure always increases with time.On the basis of testing results,the authors analyse the reasons of shaft lining fracture,such as excessively practical frozen pressure and unfavourable influence of the negative frictional force,and put forward some of the methods which could be used to prevent shaft cining fracture. |

| Keywords: | frozen pressure negative frictional force shaft lining designing parameters |
