Title in Portuguese
Desmonte de rocha e controle ambiental.
Keywords in Portuguese
Controle ambiental em mineração
Desmonte de rochas
Abstract in Portuguese
Os métodos de desmonte de rocha tem apresentado um desenvolvimento contínuo nas últimas décadas, ajudando a aumentar a produtividade e a diminuir os custos. Ao mesmo tempo, esta evolução técnica tem tido grande influência sobre os efeitos ambientais, ajudando a mitigar os problemas que envolvem poluição e incômodos à comunidade local. Alguns desses métodos já são regularmente aplicados no Brasil ao passo que outros nunca o foram. A implementação de novas tecnologias no Brasil está quase sempre associado com um melhor controle ambiental e a maioria dos casos críticos envolvem pedreiras em áreas urbanas, construção do metrô, abertura de túneis e implosões de construções civis. A implementação destas novas tecnologias tem sido acompanhada pelo monitoramento das detonações através de sismógrafos de engenharia, o que possibilita uma solução parcial dos conflitos entre mineração e comunidade e gerando novas normas. O desmonte de rocha caminha para uma solução conjugada entre eficiência e o controle ambiental, onde as técnicas de desmonte devem apresentar características ambientais positivas associadas ao monitoramento sismográfico de modo a obedecer as normas regulamentadoras.

Rock blasting and environmental control.

Environmental control in mining
Rock blasting
Abstract in English
Rock mass excavation techniques have undergone a continuous improvement in the last decades, helping to increase productivity and to lower costs. At the same time this evolution had a great influence on environmental control, helping to mitigate problems involving local communities and pollution. Some of these technologies have already been regularly used in Brazil but others never were used up to now. The implementation of new techniques in Brazil has almost always been associated with a better environmental control and the most critical cases refer to quarries in urban areas, subway construction, tunnel for roadway traffic and civil construction implosions. Besides, there is a systematic monitoring of urban quarries with engineering seismographs which have made possible at least partial solution of community conflicts, and gave origin to new regulations. The development of rock mass escavation techniques aims solutions which involve technical efficiency and environmental control, being in compliance with the legal standards.
