Abstract

Patente de Invenção:<B>"DISPOSITIVO E MéTODO DE MINERAçãO SOFTWALL"<D>. O minério conversível em lodo onde a camada estéril (50) é instável e sujeita a desmoronamento é minerada a partir de valas principais alongadas e substancialmente paralelas (60) conectadas por uma vala perpendicular (66) na base do filão mineral. Uma pluralidade de dispositivos de mineração softwall (20) suportados por equipamentos de face (22) é colocada na vala perpedicular (66). Os dispositivos tornam o material mineral lodoso e deslocam-se para dentro do filão mineral (56) à medida que a camda estéril desmorona-se atrás dos dispositivos de mineração. A camada estéril desmoronada (54) é suplementada conforme necessário com material injetado. O mineral lodoso flui para as valas paralelas (60) para remoção para a superfície. Após os dispositivos softwall terem avançado o comprimento das valas paralelas (60), os dispositivos são retirados e colocados em valas adicionalmente desenvolvidas em outros locais na reserva de minério.
