A mixture of petroleum or natural gas for closing - consists of a thermite mixture bores, at least one rare earth metal is added to the additive from a proportion of 1.5 mass % - the mixture. The aluminothermic reaction a mixture after ignition and end forms a molten thermite steel, having a reduced surface tension and therefore materials such as concrete - for environment, rock particles and the steel lining the bore of a pipe within a heat affected zone - an improved wetting and integration capacity. It generates closure body, which projects the surrounding mountains, thus anchored in this is permanent and reliable sealing of the bore is adapted and representing.
