Research methods are analytical and statistical. Nonconventional fastening in the form of united on two or on three steel-polymer rope anchors is intended for interfaces of lavas with drifts, fixed combined (frame-anchor) fastening. Its effective area applications does not depend on presence of a strong basic roof of preparatory development and extends on reusable developments by a choice of parameters according to requirements of standard documents operating in branch. Effective scope of "insular" steel-polymer fastenings of interfaces of lavas with drifts and the mechanized fastening of "window" of a lava with drift extends on excavation sites fulfilled on pillar working out system, with development repayment after a lava, on depth up to 700 m, where capacity of containing breeds not less average amount mountain pressure. Parameters "insular" fastenings pay off so that the distance between strengthening bushes corresponded to length of overlapping or beams of grab of the mechanized fastening. Scope - the mines of Ukraine fulfilling coal layers with a corner of falling up to 35 °. Product Description popup.authors Бузинник В.Н. Булатніков О.А. Дубов Є.Д. Кірін В.М. Сімченко Л.П.
