Poljakov of National Academy of Sciences of Ukraine popup.description2  As a result of the work, laboratory tests of the metal support KShPU 11.7 from SVP 19 of low-alloy steel 20G2AFps were carried out, the information obtained was analyzed and the deformation-force characteristics of the specified support were established, which are the basis for changes in the technical conditions for the production of supports. Implementation results - the obtained deformation-force characteristics of the metal support KShPU 11.7 from SVP 19 from low-alloy steel 20G2AFps manufactured by Pershotravensky Mechanical Repair Plant LLC allowed changes to be made to the technical conditions for the manufacture of KShPU support from new steel, which allowed to reduce metal consumption at the manufacture of lining, reduce the mass of the set of arch lining and its cost, increase the manufacturability of the construction of this lining without losing the quality of the lining and the safety of the operation of the lining (due to so reducing the volume and cost of repairs of mining, to increase their useful life). In general, this will improve the safety of mining operations at enterprises that use the specified KShPU support when attaching mine workings.
