under deep buried foundation, in erection of mine pit with shape that corresponds to foundation, filling of filled layer of soil onto mine pit bottom and its compaction, erection of curb with reinforcement frame inside and its filling with high grade concrete. Foundation, which is solid in plan, is given convex spherical shape, which is inscribed in plan into configuration of monolithic foundation by radius of circumference, radius of sphere is identified by given dependencies, as well as maximum angle of elastic semi-contact of foundation sphere with soil foundation, pressure of structural tensile strength of foundation, central critical pressure under center of sphere in maximum elastic base. Bottom of mine pit for concave foundation is arranged with response spherical groove.;EFFECT: improved bearing capacity of foundation, improved elastic contact interaction of foundation with underlying soil foundation.;2 cl, 7 dwg"/>
