MECHANIZED SUPPORT OF PANEL UNIT

摘要

A mechanized support of panel unit has main and supplementary sections that alternate, at that in the goaf section of the support main sections are hinged to neighboring supplementary sections, in the goaf side of support neighboring main sections are hinged to each other, at that the bases of the main sections are hinged to bases of the adjoining supplementary sections by means of propulsion hydro-jacks, and support is equipped with supply hydro-jacks for connection to basic beam of conveyor-plough. To provide more uniform distribution of load on support elements, to exclude possible freezing of sections in process of motion of support or its turn at way shaft (slope) that is to be penetrated once again or suppressed, the hinge links in goaf side of the support are arranged as flat and/or spatial hinges, links of hinged joints in face section of the support are made elastic, at that l
