Abstract

Equipments pour l'excavation du sous-sol, à l'aide d'un transformateur d'énergie cinétique qui transforme la vapeur ou le gaz dégageant une énergie haute température générée par l'action thermique de la puissance électrique, en énergie cinétique, et qui génère un fluide de travail qui permet l'excavation du sous-sol en passant dans le sous-sol d'excavation. Un excavateur de sous-sol, un appareil d'alimentation en énergie thermique et un appareil d'enlèvement de matériaux excavés sont décrits. Selon les équipements de l'invention, le facteur de charge des centrales électriques peut être amélioré la nuit au moyen de l'énergie électrique.
