In the process of developing the general exploitation and disposal plan for the Deonai, CocSau and Caoson coal mines, use should be taken into account the maximum internal disposal sites to reduce the transport supply and facilitate the environmental restoration work after exploitation. However, in the geological conditions of these coal mines, in order to ensure the space to exploit and make full use of useful minerals, it is necessary to calculate the economic efficiency when building the exploitation and disposal plan. The content of the article is based on the criteria of optimum transportation flows of rock in the arrangement of waste disposal when exploiting a group of three open-pit mines Deo Nai, Coc Sau and Cao Son.
