FIELD: mining.
SUBSTANCE: proposed method comprises the steps that follow. Top soil layer is removed to be preserves or to be transferred to territories to be reclaimed, loosening, loading and conveying stripped rock to make the waste dumps, dislodging, loading and coal transfer to storage and reclamation of dumps. Note here that seam weathered coal approaching the day surface is extracted and stored separately. Waste dumps are levelled to apply soil and weathered coal layers thereon. Produced layer is loosened with stripped rock and rolled.
EFFECT: higher efficiency.
