FIELD: mining industry.
SUBSTANCE: method includes cutting well field portions by driving bed and field mines. At mine fields to be prepared with weak rock stability driving of several field preparatory mines is performed at portion of field with width determined from formula. Bed preparation mines on same portion are driven alter, with displacement of cleaning operations from these may be driven in portions, at which their stability is provided for technological time period with inter-drift blocks of given rigidity.
EFFECT: higher safety.
