Abstract

método para explodir rocha. um método de explodir rocha, em mineração para material recuperável, compreendendo fazer furos de explodir em uma zona de explosão (1), carregar os furos de explodir com explosivos e então disparar os explosivos em um único ciclo de perfuração, carga e explosão. a zona de explosão compreende uma zona de explosão de alta energia, em que furos de explodir (2) são parcialmente carregados com um primeiro explosivo (5) para prover uma camada de alta energia da zona de explosão de alta energia, tendo um fator de pólvora de pelo menos 1,75 kg de explosivo por metro cúbico de rocha não explodida na camada de alta energia e em que pelo menos alguns desses furos de explodir são também carregados com um segundo explosivo (6) para prover uma camada de baixa energia na zona de explosão de alta energia entre a camada de alta energia e a extremidade adjacente desses furos de explodir, dita camada de baixa energia tendo um fator de pólvora que é pelo menos um fator de dois mais baixo do que o fator de pólvora de dita camada de alta energia. o método de explosão de alta energia provê melhorada fragmentação de rocha, através da concentração de energia explosiva aumentada, enquanto simultaneamente aliviando os efeitos de explosão ambientais deletérios.
