Classification of reserves of upland ore deposits developed by the open-underground method

The article considers reserves adjacent directly to the marginal contour of the quarry or located near it and subject to underground refinement. When classifying reserves of deposits developed by the open-underground method, different classification criteria are used: distance from the limit contour of the quarry, location in relation to the contour of the quarry, the method of developing reserves and the geomechanical effect of quarry excavation. Taking into account the above, a classification of reserves of upland ore deposits has been developed.
