It is established that the Planning of open-cast mining facilities should provide for the implementation of those technological schemes that avoid additional land disturbances and maintain the planned output in accordance with the demand for minerals. The methodical approach to an estimation of expediency of reproduction of the earths of various degree of infringement in the conditions of open mining at the future cost of these earths is offered. The parameters of manganese raw material extraction technology are determined, which contribute to the formation of high value of reclaimed lands. Conditions of the use of recommended technological schemes while mining horizontal deposits were described. Economically expedient reserves of land restoration throughout the disturbance area depending on the land reclamation purpose were identified.
