Abstract
CETTE INVENTION CONCERNE UNE PILE DE SOUTENEMENT POUR EXPLOITATIONS MINIERES AU FOND. CETTE PILE COMPREND UNE SEMELLE, UN BOUCLIER DE FOUDROYAGE MONTE A ARTICULATION ENTRE LES EXTREMITES ORIENTEES VERS LE REMBLAI DE CETTE SEMELLE ET D'UN CHAPEAU, ET DES ETANCONS SUPPORTANT LA CHARGE EXERCEE PAR LE TOIT ET INCLINES D'UNE PART VERS LE FRONT DE TAILLE ET D'AUTRE PART VERS LE REMBLAI. AU MOINS UN ETANCON INCLINE VERS LE FRONT DE TAILLE ET UN ETANCON INCLINE VERS LE REMBLAI ATTAQUENT LE CHAPEAU. L'ETANCON INCLINE VERS LE REMBLAI EST ARTICULE SUR LE CHAPEAU EN UN POINT QUI EST SITUE VERS LE REMBLAI PAR RAPPORT AU POINT D'ARTICULATION DU BOUCLIER DE FOUDROYAGE SUR CE CHAPEAU. CET AGENCEMENT FOURNIT POUR LA PILE UNE PORTANCE AMELIOREE POUR TOUTES LES EPAISSEURS DE VEINE RENCONTREES.
