FIELD: oil-and-gas industry.
SUBSTANCE: deposit contains the rock of valuable mineral and the other mineral. Proposed method comprises steps that follow: drilling for rock extraction, registration of predefined drilling parameter, registration of measured magnitude describing drilling unit operating conditions and computation of exclusion of measured magnitude dependence on drilling parameter. Characteristic dependent on rock texture is obtained. This characteristic is used as the measure of mineral grain for valuable mineral in rock and for definition of optimum grinding of minerals at rock grinding.
EFFECT: increased yield.
