Abstract

The article deals with the development of solutions for hardening, strengthening quarry slopes anddust suppression on the quarry roads. If, for the prevention of collapses and landslides, the man-madeincrease of the large rock massifs’s strengthening is not yet practical, then the prevention of deformationsof individual ledges and prevention of scree formation from the surface of slopes by artificial reinforcementis now being used in domestic and foreign quarries. In most quarries, rocks forming non-working beads are heterogeneous in structure and physical and mechanical properties. Even in relatively homogeneouseruptions of the rocks of the open field, there are usually many zones of tectonic disturbance.Depending on their size and spatial orientation, they have a more or less significant influence on thestability of the beads and ledges. With the help of strengthening, we can slow down the processes ofweathering and crumbling of rocks, prevent the collapse of ledges and the crumbling of rocks from thesurface of slopes. Hardening of the rock massif on the weakened sections is achieved by introducing intothe cracks of the massif of substances, which after hardening and setting the rock significantly increase itsresistance to shift. The introduction of reinforcing substance into the bulk is carried out under pressure,and as a hardening material, we consider cement mortars, silicates and polymer resins. The most widespreadamong hardening methods was rock cementation, when working in aquifers rocks, strengtheningunstable and disturbed massifs. The area of its application is an array composed of rocks from highlyfractured rocky and semicallic to coarse-grained sands and pebbles in the existence of cracks in the rocksproviding access to the solute cement in the fracture.
