FIELD: oil and gas industry.
SUBSTANCE: invention relates to the method and device for production increasing at the field containing rock that includes at least one mineral of valuable material opened by tock grinding, and at least one other mineral, at that mineral of the valuable material has higher density the at least one other mineral. At that the method is characterised by the following stages: drilling using the drill rig for rock extraction. At that the drill fines are produced, aerosol is generated, it contains drill fines and gas flow, aerosol is transferred from the drill rig to at least one air separator; flow classification is performed, at that at least two fractions are created, they include particles of the appropriate equal-falling drill fines; and properties of at least one fraction are determined, this fraction is used as measure determining optimal degree of the rock grinding.
EFFECT: increased field production.
