Abstract
SISTEMA DE ENTIBADO PROGRESIVO, UTILIZABLE ESPECIALMENTE EN UNA ESTRATIFICACION INCLINADA CON FRENTE DE ATAQUE INVERTIDO. CONSTA DE UNA FILA DE UNIDADES DE ENTIBACION HIDRAULICAS (A, B, C, D, E, F), ESPECIALMENTE ESCUDOS DE ENTIBACION O SIMILARES, ESCALONADOS ENTRE SI EN EL BUZAMIENTO (13), QUE PUEDEN AVANZAR EN EL SENTIDO DE EXPLOTACION (14) MEDIANTE MECANISMOS DE AVANCE, COMPRENDIENDO CADA UNA DE DICHAS UNIDADES DE ENTIBACION DOS ESTEMPLES HIDRAULICOS (15, 16) YUXTAPUESTOS TRANSVERSALMENTE RESPECTO AL SENTIDO DE AVANCE (14). DENTRO DE LAS DISTINTAS UNIDADES DE ENTIBACION, LOS ESTEMPLES HIDRAULICOS ESTAN DESPLAZADOS ENTRE SI EN EL SENTIDO DE AVANCE, Y EN LA POSICION BASICA DE LA ENTIBACION PROGRESIVA FORMAN UNA FILA DE ESTEMPLES (18) QUE TRANSCURRE PARALELA AL FRENTE DE ATAQUE.
