Comments on the workings information

  • LAS LABORES MINERAS SE HAN INICIADO A PARTIR DE PIQUES, SEGUIDOS DE GALERIAS SOBRE VETA. EL ACCESO AL INTERIOR DE LA MINA SE EFECTUA MEDIANTE UN PIQUE DE 65 M. DE PROFUNDIDAD, PARCIALMENTE DERRUMBADO, POR LO QUE EL TRAFICO DE PERSONAS DEBE DESVIARSE A TRAVES DE UN SEGUNDO PIQUE A UNOS 40 M. DE DISTANCIA HACIA EL ESTE. PARA LA EXTRACCION DE MINERAL, SE UTILIZA OTRO PIQUE. EXISTEN 3 NIVELES, DE LOS CUALES SOLO EL INFERIOR ESTA EN ACTIVIDAD; TIENE UNA GALERIA 25 M. HACIA EL ESTE, Y OTRA DE 30 M. HACIA EL OESTE
