The structural characteristics of large-bore column and its application in cover hydraulic support were described. The piston cavity pressure characteristics were analyzed under a load such as dual telescopic column. A working pressure of the cylinder and the theoretical basis of using safety valve of large flow were established. By using MATLAB programming,the checking computations for cylinder under varying parameters,pressure limits and burst pressure calculation process were realized. By using ANSYS,finite el-ement analysis of deformation of the cylinder was done. The method can also be used for complex product design process.
