Technological solutions development for mining adjacent rock mass and pit reserves taking into account geomechanical assessment of the deposit

Abstract: Purpose. The assessment of options for opening and mining the upper tier of Oleniy Ruchey apatite nepheline deposits and technological solutions development taking into account geomechanical calculations of open pit slopes and benches stability, both on the marginal contour and when changing the design values of the slope parameters, open pit benches and the stability safety factor to establish the marginal maximum accepted under the condition of the values stability.Methodology. Searching for technological so… Show more

“…The effectiveness of using one or another open-pit transport scheme depends on the level of technical and economic indicators both directly during the rock mass transportation and during related cargo operations. In this case, the organization of transshipment operations with the simultaneous use of dump trucks and road trains in one direction of rock transportation is of great importance [30]- [32].…”
