Abstract

CONTROL HIDRAULICO DE UNA ENTIBACION, ESPECIALMENTE ELECTROHIDRAULICO, PARA EXPLOTACIONES MINERAS SUBTERRANEAS. CONSTA DE DISPOSITIVOS DE VALVULAS DISTRIBUIDORAS ASOCIADOS CON CADA UNA DE LAS UNIDADES DE ENTIBACION HIDRAULICAS, ESTANDO DICHAS VALVULAS CONECTADAS A LA TUBERIA DE PRESION Y A LA TUBERIA DE RETORNO DE UN EQUIPO DE BOMBA CENTRAL; DE UNA VALVULA DE CORTOCIRCUITO CONECTADA ENTRE LA TUBERIA DE PRESION Y LA TUBERIA DE RETORNO; Y DE UNA PLURALIDAD DE INTERRUPTORES DE EMERGENCIA DISTRIBUIDOS A LO LARGO DE LA EXPLOTACION, QUE AL SER ACCIONADOS HACEN QUE LA VALVULA DE CORTOCIRCUITO SE CONMUTE EN EL SENTIDO DE ENLAZAR LA TUBERIA DE PRESION CON LA TUBERIA DE RETORNO.
