A vibração é o efeito que causa maiores danos nas operações de desmonte com uso de explosivos. O objetivo é estudar a vibração resultante do desmonte de rochas com explosivos, estudar os critérios de avaliação das vibrações. Envolve ensaios de campo e monitoramento ambiental de uma mineração de calcário (CIMPOR). Apresenta, os primeiros estudos do fenômeno da vibração; apresenta um conceito da vibração resultante do desmonte de rocha com explosivos, tratando, dos critérios de avaliação destas vibrações. Apresenta um resumo das principais normas técnicas internacionais e nacionais bem como as formas do modo como as ondas P e S se propagam no solo. A área monitorada foi em João Pessoa - ParaÃba. As medições ocorreram de janeiro de 2003 a dezembro de 2005. Foram realizadas mais de quatro centenas de medições, para encontrar a lei de propagação da vibração pela quantidade máxima de energia a ser liberada por espera para uma determinada distância. Para análise dos resultados. Percebe-se que o grau de dispersão diminui com a utilização da energia do explosivo liberada por espera em relação à utilização com carga (peso) do explosivo por espera.
