Novas tecnologias de avaliação de reservas e planejamento de lavra foram desenvolvidas a partir do advento da computação. A teoria geoestatística passou a ser reconhecida como atributo primordial na avaliação dos recursos e reservas. Diversos softwares de planejamento de lavra e avaliação de depósitos incorporaram a geoestatística e algoritmos, que facilitaram e melhoraram o desenho de cavas. A visualização em três dimensões tornou mais fácil o planejamento e a compreensão do comportamento dos depósitos minerais. ... As grandes minas a céu aberto e até mesmo minas de porte médio, nos USA, Austrália e Canadá caracterizam-se por uma intensa utilização de equipamentos de grande porte para as operações de carregamento e transporte, perfuração com furos de diâmetros grandes (>250mm), explosivos do tipo blend bombeados, utilização de GPS, gerenciamento on-line das operações de lavra e pouca mão de obra. Os métodos de lavra mais utilizados são o método de lavra em tiras ou fatias (strip mining e cast mining e em cava (open pit mining), esse último ilustrado na Figura 1. A figura 2 ilustra o porte de equipamentos usados na Mina de Fort Knox no Alaska. http://www.cprm.gov.br/publique/media/ten_tecno_brasil.pdf |
