Abstract: It is very important for mine to develop transportation system，and its layout is related to the economic benefits of the whole mine. In order to expand and integrate the production of Hongge Iron Mine and Miaozigou Iron Mine in west of Panzhihua，two schemes of crushing + belt transportation and au⁃ tomobile transportation were first proposed，and the preliminary design of the scheme was carried out. Sub⁃ sequently，for the transport of ore and waste rock，the cumulative present value of investment cost compari⁃ son method to carry out technical and economic comparison program. The results show that the present val⁃ ue of cumulative investment cost of crushing + belt transportation system in stope is lower than that of auto⁃ mobile transportation system. The research results can provide reference for similar mines.
