Scientific justification of commercial amber production without crushing in work face

The production technology accepted at the Kaliningrad Amber Factory gives place to mineral breakage during muck jetting, grinding in suction dredge and abrasion in pulp slurry line 1000–1600 m long. Aimed to avoid amber crushing under giant jets, the balance is found between the equipment parameters and strength of amber-bearing rock (Blue Earth). The curves of the axial dynamic pressure of jets, working head of water ahead of the jet nozzle, the nozzle diameter and the jet–face spacing are plotted. The distance range between the jet and the face, such that the Blue Earth is efficiently treated and amber crushing is eliminated, is determined. For elimination of amber grinding in suction dredge, it is proposed to use dewatering elevator. In geotechnical conditions of a production face, the best way of lifting amber to an unloading point is using a movable bucket–chain elevator with inclined upward flow and gravity unloading. The bucket of the elevator should be perforated for dehydrating of amber from pulp slurry, with possibility of classification, i.e. extraction of coarse fractions only.
