deposits. Methodology. Zonal structuring indices of massif around mine workings were …

Deterioration of mining conditions at mining deposits by open pit methods (increased mining
depths, reduced ore deposit thickness) leads to an increase in mining costs. In Ukraine, to …

Purpose is development of the methods to predict indices of iron-ore deposits relying upon
the improvement of available techniques as well as formulation of new geometrization …

Underground mining has a significant influence on ground movement, which induces
serious environmental disturbances on land. Movements of the rock strata can be the cause …

Annotation. In terms of mining and geological structure, ore deposits are complex-structured
and composed of single, parallel-contiguous ore bodies. The reserves of barren or ore …
