Besed on the experiments, the boundary condition of digging were determined in consideration of equation of digging locus and mining technology. Guided by mind of system theory, based on the integral digging circulation process, the difficult point of creating mathematical model was solved.The multiple object function was created for the parameters in digging process and geometrical parameters of working mechanism. The parameters were optimized by applying complex method, and then the rational parameters of working mechanism were determinecl. This is of universal significance, and also have practically instructive significance for design.
