FIELD: mining.
SUBSTANCE: within the ore body, the well fans are drilled, charged and short-delayed detonated. The distance between the ends (bottoms) in the fan outer wells and the contour of the ore body is determined taking into account explosive detonation parameters, physical-technical properties and fracture parameters of the ore body, and the magnitude of rock pressure.
EFFECT: size reduction disorders of hosting rocks and ore reduction dilution during its shipment, reducing the volume of the drilling and weight BB.
