Abstract(s)
A atividade mineira é uma das atividades mais antigas e importantes da
humanidade, sendo uma atividade que se encontra intimamente interligada ao avanço e
evolução da tecnologia.
A crescente procura de matérias-primas, principalmente de metais, envolve
inevitavelmente a pesquisa e prospeção dos mesmos e consequente abertura de pedreiras e
minas. A par com este crescimento está a preocupação cada vez maior dos impactos
inerentes à abertura e funcionamento de minas e pedreiras. Sem soluções eficazes e
permanentes que permitam o fim da exploração mineira, a prioridade é garantir que esta
seja efetuada de forma segura, com uma gestão sustentável e com a redução, o mais
possível, dos efeitos negativos inerentes.
Existem principalmente muitas pequenas ou médias empresas mineiras, que com
capital mais reduzido, possuem uma gestão mineira menos eficiente e sustentável.
Com o desenvolvimento de uma metodologia baseada na integração de técnicas de
geomática, como a deteção remota com recurso a veículos aéreos não tripulados e
processamentos fotogramétricos, com os Sistemas de Informação Geográfica e com a
aplicação da mesma num caso de estudo na Mina C-57 “Castanho” (Gonçalo, Portugal), foi
possível demonstrar que uma pequena ou média empresa mineira a céu aberto pode ter ao
seu dispor, de forma fácil e de relativo baixo custo, ferramentas poderosas que permitem
obter um conjunto de bases de dados continuamente atualizados, aumentar a eficácia de
todas as etapas e operações inerentes à mina e, de uma forma muito importante, contribuir
para uma exploração mineira mais segura e sustentável com a redução de riscos intrínsecos
à própria atividade mineira.
The mining activity is one of the oldest and most important activities of humanity and is an activity, which It´s connected with the advancement and evolution of technology. The growing demand for raw materials, mainly of metals, inevitably involves researching and prospecting them andthe consequent opening of quarries andmines. Along with this increase,there is a growing concern aboutthe impacts inherent to the opening and operation of mines and quarries. Without effective and permanent solutions that allow the end of mining, the priority is to ensure that It´s done in a safe way, with a sustainable management and with the reduction, as much as possible, of the inherent negative effects. There are mainly many, small and medium-sized mining companies, which with smaller capital, have less efficient and sustainable mining management. With the development of a methodology, based on the integration of geomatics techniques, such as remote sensing using unmanned aerial vehicle and photogrammetric processing, with Geographic Information Systems and with the application of the methodology in a case study at Mine C-57 “Castanho” (Gonçalo, Portugal), it was possible to demonstrate, that a small or medium-sized company open pit mining can have access, easily and relatively low cost, powerful tools that allow to obtain a set of continuously updated databases, increase the effectiveness of all stages and operations inherent to the mine and, most important, contribute to safer and more sustainable mining with the reduction of risks intrinsic to the mining activity itself.
