FIELD: mining.
SUBSTANCE: method comprises an extraction of overburden rocks by longitudinal stripping cuts with placement on their bottom of a free strip, handling of overburdens from working face of the longitudinal stripping cut and their storage in an internal dump. The extraction of overburdens by longitudinal stripping cuts with placement on their bottom of a free strip, handling of overburdens from working face of the longitudinal stripping cut and their storage in an internal dump at the edge of these stripping cuts are performed within the extraction block. Meanwhile along the bottom edge of the internal dump of the extraction block an additional free strip is placed, which is used for storage of overburdens, with forming of internal dump.
EFFECT: improvement of performance of direct mining method at the expense of increase of productivity by minimising of length and time of idle running of the stripping equipment.
