Abstract | |
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. (AU) |
