English abstract

The subject of the study is the surface mining the mineral of deep occurrence and further reclamation of disturbed land. The purpose of the work is the scientific and practical task of the study is to jus- tify a new technology of flooded open-cast mines reclamation, taking into account depth of mine, its flooding level and the physical and mechanical properties of rocks. The calculations were performed in manual and automatic search mode for the most stressed sliding surface on several calculated sliding surfaces. The formula for calculating the value of the distance from the safety embankment to the axis of move- ment of the excavator is obtained using the cosine theorem and a number of trigono- metric identities. New technology is based on the phenomenon of when water flooding of the slope reaches the critical value at the level of 0,19 from the total height of the tier slope, there is an increase in stability and a decrease in the width of the prism of a possible landslide by in- creasing the influence of water retaining forces in the open pit space.
