Kind Code:
A
Abstract:
In a method for manufacturing a backing material to maintain open drill holes obtained by hydraulic means and drilled in deep rock-containers of natural gas, there is added to dehydrated bauxite a mixture of at least two alkaline-earth liquid compounds which are thermally decomposable in a proportion from 5 to 20 %. The decomposition ranges of each liquid compound are between 100 and 900oC and overlap each other. Before the sintering operation which takes place preferably at a temperature not exceeding 1450oC, a mechanical granulation of the compounds is carried out.
