Abstract
Device for sealing boreholes, of the kind comprising a truncated cone, with a diameter greater than the diameter of the hole and another diameter smaller than the diameter of the hole, said cone having a longitudinal channel, characterized by the fact that the cone of rather elastic material, for example plastic, has the smallest diameter of its channel, only somewhat smaller than the smallest outer diameter of the cone, which produces a relatively thin wall thereof, and thereby, provides the elastic properties of the wall; and that the smallest diameter of the channel corresponds essentially to the diameter of an explosive charge or the like, which is introduced into the hole through the cone channel.
