A minera\u00e7\u00e3o subterr\u00e2nea de rocha dura e o processo de minera\u00e7\u00e3o de rocha macia s\u00e3o os dois tipos de m\u00e9todos de minera\u00e7\u00e3o subterr\u00e2nea. O primeiro refere-se \u00e0 extra\u00e7\u00e3o de minerais duros, como ouro, prata, zinco e n\u00edquel, enquanto o segundo refere-se a m\u00e9todos de extra\u00e7\u00e3o de minerais macios, como sal e carv\u00e3o.<\/p>\n<p>H\u00e1 dois est\u00e1gios principais na minera\u00e7\u00e3o subterr\u00e2nea: pesquisa e produ\u00e7\u00e3o. A primeira envolve a escava\u00e7\u00e3o de res\u00edduos de rocha para obter acesso a pedras preciosas, min\u00e9rios e minerais. A detona\u00e7\u00e3o, a classifica\u00e7\u00e3o, a coloca\u00e7\u00e3o de refor\u00e7o e os explosivos s\u00e3o etapas do processo de minera\u00e7\u00e3o de desenvolvimento.<\/p>\n<p>Por outro lado, a minera\u00e7\u00e3o de produ\u00e7\u00e3o \u00e9 dividida em dois est\u00e1gios: minera\u00e7\u00e3o de furos mais curtos e minera\u00e7\u00e3o de furos profundos. A minera\u00e7\u00e3o de furos rasos \u00e9 compar\u00e1vel \u00e0 minera\u00e7\u00e3o de desenvolvimento, pois envolve a extra\u00e7\u00e3o do min\u00e9rio real. V\u00e1rias escava\u00e7\u00f5es dentro do min\u00e9rio ou abaixo de sua superf\u00edcie constituem a minera\u00e7\u00e3o de furos longos.<\/p>\n<p>Nenhum segmento foi deixado intocado desde o in\u00edcio da era digital, e a tecnologia de minera\u00e7\u00e3o subterr\u00e2nea n\u00e3o \u00e9 exce\u00e7\u00e3o. Como a minera\u00e7\u00e3o tem um efeito t\u00e3o significativo na economia dos pa\u00edses e na vida de milh\u00f5es de pessoas, era inevit\u00e1vel que os acad\u00eamicos criassem v\u00e1rios m\u00e9todos para melhorar os processos de minera\u00e7\u00e3o convencionais usando a tecnologia, como fizeram empresas como a Newtrax. Aqui est\u00e3o alguns dos avan\u00e7os t\u00e9cnicos mais significativos na minera\u00e7\u00e3o subterr\u00e2nea:<\/p>\n<h3>IoT e minera\u00e7\u00e3o<\/h3>\n<p>Espera-se que a Internet das Coisas, ou IoT, otimize e melhore as opera\u00e7\u00f5es de minera\u00e7\u00e3o muito mais do que atualmente. Isso ocorre porque a Internet das Coisas permite a coleta de grandes quantidades de dados produzidos pelas atividades de minera\u00e7\u00e3o.<\/p>\n<p>Essas informa\u00e7\u00f5es podem ser utilizadas para monitorar remotamente as opera\u00e7\u00f5es, tornando-as mais seguras, mais produtivas e mais sustent\u00e1veis. As informa\u00e7\u00f5es coletadas durante as opera\u00e7\u00f5es de minera\u00e7\u00e3o podem ser usadas para determinar quanto tempo os caminh\u00f5es de minera\u00e7\u00e3o passam esperando (o que equivale a recursos desperdi\u00e7ados), quanto tempo leva para carregar o material nos caminh\u00f5es, quanta manuten\u00e7\u00e3o \u00e9 necess\u00e1ria e assim por diante.<\/p>\n<p>A Internet das Coisas (IoT) \u00e9 uma nova tecnologia de rede baseada na conflu\u00eancia de tecnologias sem fio, sistemas microeletromec\u00e2nicos (MEMS) e a Internet, que pode revolucionar o setor de minera\u00e7\u00e3o com a introdu\u00e7\u00e3o de novos m\u00e9todos para manter a seguran\u00e7a e a produ\u00e7\u00e3o das minas.<\/p>\n<p>A tecnologia envolve o uso de dispositivos de identifica\u00e7\u00e3o por radiofrequ\u00eancia (RFID) e tecnologias de sensores para criar identificadores exclusivos para m\u00e1quinas, frotas e pessoas, permitindo que eles se movimentem e obtenham dados em uma rede sem a necessidade de sistemas de comunica\u00e7\u00e3o entre humanos ou entre humanos e computadores na minera\u00e7\u00e3o subterr\u00e2nea. A plataforma de IoT pode melhorar a rastreabilidade e a visibilidade de toda a opera\u00e7\u00e3o de minera\u00e7\u00e3o. Al\u00e9m disso, ela tamb\u00e9m pode permitir que os computadores observem, identifiquem e compreendam diferentes aspectos das opera\u00e7\u00f5es de minera\u00e7\u00e3o sem a necessidade de interven\u00e7\u00e3o humana e automatizem e aprimorem a manuten\u00e7\u00e3o e a opera\u00e7\u00e3o das m\u00e1quinas.<\/p>\n<p>A Cisco e outras empresas de rede colaboram ativamente com parceiros do setor para oferecer solu\u00e7\u00f5es baseadas em IoT adaptadas ao setor de minera\u00e7\u00e3o.<\/p>\n<h3>Minera\u00e7\u00e3o inteligente<\/h3>\n<p>Espera-se que o surgimento da minera\u00e7\u00e3o inteligente revolucione o setor de minera\u00e7\u00e3o nos pr\u00f3ximos anos. A minera\u00e7\u00e3o \u00e9 controlada por uma combina\u00e7\u00e3o de for\u00e7a de trabalho e c\u00e1lculos matem\u00e1ticos - espera-se que as minas inteligentes removam o elemento da for\u00e7a de trabalho do processo de minera\u00e7\u00e3o, otimizando assim todo o processo de minera\u00e7\u00e3o e tornando-o mais eficiente em termos de custo e energia. Grande parte do trabalho perigoso que as pessoas costumavam realizar agora ser\u00e1 feito por m\u00e1quinas que trabalham de acordo com um cronograma predefinido e s\u00e3o automatizadas.<\/p>\n<h3>Tecnologia blockchain e minera\u00e7\u00e3o<\/h3>\n<p>O aumento dos custos e as preocupa\u00e7\u00f5es com a efici\u00eancia levaram o setor de minera\u00e7\u00e3o a desenvolver t\u00e9cnicas eficientes e sustent\u00e1veis que substituem ou complementam os processos de minera\u00e7\u00e3o convencionais. Uma grande parte dessa efici\u00eancia vem da otimiza\u00e7\u00e3o da cadeia de suprimentos de minera\u00e7\u00e3o, e o blockchain \u00e9 um passo nessa dire\u00e7\u00e3o.<\/p>\n<p>Com o uso da tecnologia blockchain nas cadeias de suprimentos dos processos de minera\u00e7\u00e3o, \u00e9 poss\u00edvel estabelecer redes de distribui\u00e7\u00e3o transparentes e instilar rastreabilidade e seguran\u00e7a.<\/p>\n<h3>Tecnologias para gera\u00e7\u00e3o de imagens 3D<\/h3>\n<p>A gera\u00e7\u00e3o de imagens 3D revolucionou a explora\u00e7\u00e3o de minas em larga escala em termos de minera\u00e7\u00e3o do sistema de detec\u00e7\u00e3o de proximidade e continua a se mostrar promissora em uma variedade de novas tecnologias. Embora os levantamentos s\u00edsmicos para investigar a geologia de locais de minera\u00e7\u00e3o em potencial n\u00e3o sejam novos, a tecnologia de gera\u00e7\u00e3o de imagens 3D aumentou significativamente a efic\u00e1cia dessas investiga\u00e7\u00f5es.<\/p>\n<p>A digitaliza\u00e7\u00e3o a laser em 3D \u00e9 uma nova t\u00e9cnica de gera\u00e7\u00e3o de imagens tridimensionais que usa luz laser para coletar dados espaciais e permite que os ge\u00f3logos criem mapas geol\u00f3gicos em 3D integrando dados de mapeamento de superf\u00edcie.<\/p>\n<p>Apesar de seu amplo uso em outras \u00e1reas, como engenharia, projeto arquitet\u00f4nico e investiga\u00e7\u00e3o forense, o tra\u00e7ado de raios 3D \u00e9 um m\u00e9todo relativamente novo para o setor de minera\u00e7\u00e3o. Engenheiros de rocha, engenheiros de fluxo de ar, oficiais de seguran\u00e7a e aqueles que pesquisam ambientes de minera\u00e7\u00e3o perigosos ou inacess\u00edveis t\u00eam se beneficiado dessa t\u00e9cnica.<\/p>\n<h3>Perfura\u00e7\u00e3o automatizada<\/h3>\n<p>As opera\u00e7\u00f5es de perfura\u00e7\u00e3o de superf\u00edcie podem ser mais seguras e eficientes com o uso de sistemas de perfura\u00e7\u00e3o rob\u00f3ticos e teleoperados. Um sistema de perfura\u00e7\u00e3o teleoperado consiste em uma esta\u00e7\u00e3o de opera\u00e7\u00e3o f\u00e1cil de usar que pode ser instalada em v\u00e1rias plataformas m\u00f3veis conectadas \u00e0 rede sem fio da plataforma de perfura\u00e7\u00e3o.<\/p>\n<p>A t\u00e9cnica permite que o operador perfure a uma dist\u00e2ncia segura sem precisar se aproximar de regi\u00f5es perigosas. Com uma fotografia com controle remoto de pan\/zoom\/tilt para manuseio de hastes, perfura\u00e7\u00e3o e controles de deslocamento, transmitindo imagens em tempo real, v\u00eddeo em tempo real e comunica\u00e7\u00e3o de dados, incluindo todo o sistema de controle de perfura\u00e7\u00e3o e o status do equipamento. O sistema de rastreamento da mina subterr\u00e2nea \u00e9 exibido constantemente em uma tela gr\u00e1fica configurada no centro do operador. \u00c9 um m\u00e9todo de escava\u00e7\u00e3o de po\u00e7os e t\u00faneis que \u00e9 eficiente e eficaz.<\/p>\n<p>A minera\u00e7\u00e3o est\u00e1 se tornando mais subterr\u00e2nea \u00e0 medida que as minas a c\u00e9u aberto chegam ao fim de sua vida \u00fatil e novos dep\u00f3sitos minerais s\u00e3o descobertos nas profundezas. A constru\u00e7\u00e3o de minas subterr\u00e2neas usando equipamentos tradicionais de perfura\u00e7\u00e3o de t\u00faneis e po\u00e7os. Por outro lado, tem se mostrado tecnicamente desafiadora, cara e demorada.<\/p>\n<h3>Bact\u00e9rias que consomem cobre<\/h3>\n<p>Como a extra\u00e7\u00e3o de alguns conte\u00fados minerais n\u00e3o \u00e9 econ\u00f4mica, eles ser\u00e3o deixados no final. As empresas de minera\u00e7\u00e3o geralmente os descartam como lixo ou os utilizam como substitutos para outras opera\u00e7\u00f5es qu\u00edmicas.<\/p>\n<p>No entanto, minerais raros como o cobre est\u00e3o se tornando mais valiosos, e a recupera\u00e7\u00e3o de minerais de rejeitos pode se tornar economicamente vi\u00e1vel no futuro. A Vale, uma empresa brasileira de minera\u00e7\u00e3o, trabalha com a Universidade de S\u00e3o Paulo em um novo m\u00e9todo potencial para extrair minerais de cobre de rejeitos usando microrganismos, o que revolucionar\u00e1 o gerenciamento de rejeitos e aumentar\u00e1 a produ\u00e7\u00e3o mineral se for expandido para outros minerais. A t\u00e9cnica inovadora ajudaria a extrair minerais raros, como o cobre, que existe na forma pura em apenas 1% de cada tonelada de min\u00e9rio extra\u00eddo.<\/p>","protected":false},"excerpt":{"rendered":"<p>Mining is the source of mineral commodities mined all over the globe.
