FIELD: mining. ^ SUBSTANCE: group of inventions related to methods and devices of cumulative perforators assembly and can be used in cumulative perforators composition. Cumulative charge fixing in perforators frame method includes the cumulative charge installation on a priory created holes in the perforator framework, its diametrically opposed sides. Create two fixing leafs in the perforators framework, in area of cumulative charge installation in framework places, the nearest to cumulative charge case after its installation, by cutting framework case with ""-shaped or C-shaped uncompleted line, and located across cavity on a cumulative charge case external surface, executed before cumulative charge fixing. After cumulative charge installation into perforator case, execute cumulative charge case fixing by bending of fixing leafs till its entering into cumulative charge case external surface cavity. ^ EFFECT: cumulative charge fixing in perforator frame reliability increase. ^ 2 cl, 5 dwg |
