【 摘 要 】

The results of industrial tests of a reinforced combined support based on self-fastening anchors are presented. The approved versions of reinforced combined supports that ensure the stability of contours of mine workings in difficult mining and geological conditions of the mine "Orlovskaya" LLP "Vostoktsvetmet".
