FIELD: mining.;SUBSTANCE: dangerous landslide slope massif strengthening method by controlled improvement of stability factor to required level of dangerous landslide root massif of slope involves determination of depth to potentially deformation horizon in dangerous landslide root massif of slope, structural strength at compression of soil in this horizon, specific weight of earth cover lying above potentially deformation horizon for controlled increase of stability factor of dangerous landslide root massif of slope; cross groove is made in it, the axis of which is oriented normally to the slope edge, wide; deep; L≥2·H long, where B, H, L is width, depth and length respectively of cross groove /m/; K - stability factor; Zd - depth to potentially deformation horizon /m/; σstr - structural strength of soil of potentially deformation horizon at compression /kPa/; γ - specific weight of earth cover lying above potentially deformation horizon /kN/m3/. At that, on the slope with existing landslide cirque, groove in dangerous landslide root massif is arranged along cirque axis and the width of the above groove is where B - width of groove /m/; K - stability factor of dangerous landslide root massif with groove relative to its marginal state in the existing landslide cirque; R - bending radius of edge of dangerous landslide root massif in the existing landslide cirque /m/. Underground operated facility can be erected in groove, the rigid frame of which is attached to stable massif in rear part of the groove, e.g. by means of anchors, with possibility of draining of underground water. On the bottom of groove there can be performed the strengthening works on increasing the structural strength for soil compression of potentially deformation horizon in edge parts of dangerous landslide root massif, e.g. by injection of strengthening solution.;EFFECT: controlled improvement of stability of dangerous landslide soil massif to required level and effective use of underground space.;3 cl, 3 dwg
