ABSTRACT
The management of the state of natural and man-made massifs during the open-pit mining of mineral deposits consists in a set of measures to maintain ledges, sides of quarries and dumps in a stable, close to the limit state by changing the geometric parameters of the slopes during the development process, which ensures economical and safe mining operations. The block structure of the side array is one of the parameters affecting the strength of the rock mass, and the fillers between the block spaces are the main factor in their de-formation and destruction. In the sides of the upland quarries, not only individual blocks fall out, but also massive collapses are observed. This indicates that the filler between the block cracks has less strength than the level of the acting shear forces near the surface of the outcrop.
