Abstract. Object of study – stability of the system "mine working - support - rock massif". Purpose – to determine particularity of mine working loss stability, which equipped by geokomposite protection-supporting construction. Research method – physical modelling on equivalent materials. The bases problems, connected with the wide scale interdiction of geokomposite protection-supporting constructions, were described in this paper. The choice of research method and physical models characteristics were justified. The investigations of the geokomposite constructions deformations in smallblock medium for two models types: frame-anchor and frame-anchor-rope were implemented. Deformation characteristics were obtained and common and distinctive indications of models loss stability were established. It is shown, that loss of the geokomposite constructions stability, using frame-anchor-rope support (by change largeblock structure in smallblock) occurs at higher loads. It is shown, that these preference can be realized only in the presence of anchors with high performance, great depth of burial, as well as high strength fastening in the array.

Keywords:

 mine working, support, block structure of massif, geokomposite protection-supporting constructions, physical modelling, stability.
