dc.description.abstract | Tailings dams are structures that aims to retain the solid waste and water from
mining processes. Its analysis and planning begins with searching of location for
deployment, step on which to bind all kinds of variables that directly or indirectly
influence the work, such as geological, hydrological, tectonic, topographic,
geotechnical, environmental, social characteristics, evaluation security risks, among
others. Thus, this paper aims to present a study on the most appropriate and secure
type of busbar to design a layout structure of iron ore tailings, taking into account all
the above mentioned variables. The case study involves the assessment of sites for
location of dams of tailings disposal beneficiation of iron mine to be built in Bonito, in
the municipality of Jucurutu in Seridó Potiguar. For site selection among alternatives,
various aspects of the current state of the art were considered, one that causes the
least environmental impact, low cost investment, adding value to the product and
especially the safety of the implanted structure mitigates the concern about induced
earthquakes as a result of liquefaction wastes somatized by dams in the region, as
the tilling of Mina Bonito is located practically in the hydraulic basin dam Armando
Ribeiro in environmental protection (APA). The methodology compares induced by
dams in the semiarid region with the characteristics of the waste disposal and sterile
seismicity, taking into account the enhancement of liquefaction by the action of
seismicity in the Mina Bonito region. With the fulcrum in the methodology, we
indicated the best busbar type for disposal of tailings from iron ore or combination of
them, to be designed and built in semiarid particularly for Mina Bonito. Also presents
a number of possible uses for the tailings and in engineering activities, which may
cause processing to the common good. | |
