FIELD: mining industry.
SUBSTANCE: method includes separation of fertile layer during opening of mineral resources and stocking of rock during extraction of same, planning of open mines by backfill with rock and application of fertile layer with restoration of vegetation in accordance to land usage direction. During backfill of rocks into open mines, inclined trench is made from earth surface to open part of exposed formation outlet being left in sides of mine, which provides access and following underground extraction of left deposit resources, and is meant to be a part of payable area.
EFFECT: combination of coal extractive processes with reclamation of lands and preservation of access to concealed resources for their later extraction.
