Desmonte de rochas em área urbana com o uso de explosivos: técnicas para minimização dos impactos ambientais gerados pelas detonações - estudo de caso - Parauapebas - PA

Abstract

The dismantling of rock by explosives will be applied to the process of fragmentation and handling where such geological structure have a resistance to impede the dismantling of this by means of excavation equipment. When this operation is approaching the major urban centers such as environmental impacts: ultralançamentos fragments, generation of vibration in the ground, particulate emissions in the atmosphere, increasing levels of noise and air suppression Knowing this, we propose a work based on results of field practices and theoretical research on the topic dismantling of rocks by explosive in urban areas especially emphasizing environmental issues and setting fire to the massive plan, so that these projects can operate without major conflicts with the communities around its . The practices of this work were performed at the company Explosives Ltd. located in Bang-Pa Paraupebas where the case study took place. As this is a new development within an urban center control of particle size and minimizing the environmental impacts can define the success or failure of the venture. Focusing on these issues work then try to break the rock mass within an acceptable range of particle size and minimize these environmental impacts by making use of analytical techniques and inexpensive tools for the enterprise.
