Spiral drill pipe of rotary drill is an important component for quick and high-quality drilling process. In order to improve drilling efficiency, it＇s necessary to establish mathematical models by choosing the coal transportation capacity of spiral drill pipe on the purpose of optimum design. Using the structural parameters of spiral pipe （pitch, shaft diameter pipe） and screw speed as variables, the optimal value of the structural parameters of spiral pipe was calculated by the optimization toolbox of MATLAB, and the transportation capacity of spiral drill pipe was improved. The optimized result takes important guiding role and engineering value for the design of spiral drill pipe and the improvement of the rotary drill.
