Abstract： Under the conditions of vertical mining to horizontal mining in inclined coal seam open-pit mine, with the change of mining program, it leads to the changes of inner and outer dump program, stripping transportation distance, lifting height, the area of land and material goods flow. To solve this problem, the mine builds the economic model of dump construction development. From the inner and outer row of open-pit mine planning stream, outer dump transportation, land acquisition, inner dump dynamic development and the inner and outer rows peeling lifting height and other factors, the mine optimizes the inside and outside dump construction development program in the lifecycle. The article combines the process of vertical mining to horizontal mining to carry out research in Zhundong Open-pit Mine first mining area .
