Abstract

Изобретение относитс  к горному делу и м.б. использовано дл  поддержани  выработок (В). Цель - повышение устойчивости В.,По пласту 2 в его кровле бур т скважины (С) 5, которые располагают перпендикул рно оси В 1. В каждой С 5 размещают элементы 6 креплени , концы которых вывод т в В 1 с образованием консолей. Затем в почве пласта нарезают сегментообразные щели (Щ) так, чтобы места контакта с Щ находились под С 5. Под консольные части С 5 дл  их усилени  завод т стойки. Длину С 5 принимают большей ширины зоны пластической деформации, а глубин Щ равной ширине этой зоны. 2 ил.The invention relates to mining and m. used to support workings (B). The goal is to increase the stability of B., Over the reservoir 2, in its top a hole is drilled (C) 5, which are located perpendicular to the B axis 1. In each C 5, fastening elements 6 are placed, the ends of which are led out to B 1 to form cantilevers. Then, segmented gaps (U) are cut into the soil of the formation so that the points of contact with U are below C 5. Under the cantilever parts C 5, racks are made to reinforce them. The length of the C 5 take a greater width of the zone of plastic deformation, and the depth of U is equal to the width of this zone. 2 Il.
