ABSTRACT:
A process for enlarging or widening rock fractures in order to facilitate the recovery of deposits, such as oil or gas, comprising the emplacement of an aluminothermic mixture of aluminum and ferric oxide, and its subsequent ignition. Preferably, slag-forming products are also placed into the cavity, so as to prevent closure of the fractures after termination of the combustion process.
