No entanto, a maioria dos empres\u00e1rios est\u00e1 envolvida na minera\u00e7\u00e3o. Eles decidem se v\u00e3o usar a minera\u00e7\u00e3o subterr\u00e2nea ou a minera\u00e7\u00e3o a c\u00e9u aberto para extrair uma jazida de min\u00e9rio. Normalmente, os empres\u00e1rios consideram primeiro os benef\u00edcios econ\u00f4micos. Esta postagem apresentar\u00e1 dois m\u00e9todos de minera\u00e7\u00e3o e analisar\u00e1 como escolher o melhor m\u00e9todo de minera\u00e7\u00e3o a partir de diferentes perspectivas.<\/p>\n\n\n\n

Parte 1: defini\u00e7\u00e3o de dois m\u00e9todos de minera\u00e7\u00e3o<\/strong><\/h2>\n\n\n\n

Defini\u00e7\u00e3o de minera\u00e7\u00e3o subterr\u00e2nea<\/strong><\/h3>\n\n\n\n

\u00c9 um termo geral para minera\u00e7\u00e3o com t\u00faneis subterr\u00e2neos. Em geral, a minera\u00e7\u00e3o subterr\u00e2nea \u00e9 adequada para dep\u00f3sitos enterrados profundamente quando a minera\u00e7\u00e3o em tiras n\u00e3o \u00e9 adequada econ\u00f4mica e tecnicamente. O corpo de min\u00e9rio \u00e9 dividido em est\u00e1gios e blocos de min\u00e9rio pela engenharia de t\u00faneis subterr\u00e2neos, na qual o trabalho de minera\u00e7\u00e3o \u00e9 realizado com os blocos de min\u00e9rio como a unidade b\u00e1sica de minera\u00e7\u00e3o subterr\u00e2nea.<\/p>\n\n\n\n

Defini\u00e7\u00e3o de strip mining<\/strong><\/h3>\n\n\n\n

A minera\u00e7\u00e3o de tiras refere-se ao trabalho de minera\u00e7\u00e3o em espa\u00e7o superaberto, de acordo com as condi\u00e7\u00f5es de ocorr\u00eancia do dep\u00f3sito de min\u00e9rio, usando determinados equipamentos de minera\u00e7\u00e3o, carregamento e transporte. Portanto, a minera\u00e7\u00e3o de tiras tem baixa demanda pelo desempenho do equipamento. Muitas vezes, alguns dep\u00f3sitos s\u00e3o grandes, rasos ou at\u00e9 mesmo expostos na superf\u00edcie. Suponha que a camada de rocha esteja exposta na superf\u00edcie. A profundidade da escava\u00e7\u00e3o n\u00e3o \u00e9 grande. Os minerais podem ser extra\u00eddos diretamente no solo sem escava\u00e7\u00e3o de estradas. Portanto, \u00e9 adequado para minera\u00e7\u00e3o a c\u00e9u aberto.<\/p>\n\n\n\n

Parte dois: vantagens de ambos os m\u00e9todos de minera\u00e7\u00e3o<\/strong><\/h2>\n\n\n\n
\"fabricante<\/figure><\/div>\n\n\n\n

Vantagens da minera\u00e7\u00e3o a c\u00e9u aberto<\/strong><\/h3>\n\n\n\n

As vantagens da minera\u00e7\u00e3o em tiras incluem principalmente os seis aspectos a seguir: (1) O grau de mecaniza\u00e7\u00e3o \u00e9 alto. (2) Alta produtividade da m\u00e3o de obra. (3) O custo de minera\u00e7\u00e3o \u00e9 baixo. (4) Recupera\u00e7\u00e3o total dos recursos da minera\u00e7\u00e3o subterr\u00e2nea. (5) O tempo de constru\u00e7\u00e3o da infraestrutura \u00e9 curto. (6) Boas condi\u00e7\u00f5es de trabalho.<\/p>\n\n\n\n

Vantagens da minera\u00e7\u00e3o subterr\u00e2nea<\/strong><\/h3>\n\n\n\n

Em compara\u00e7\u00e3o com a minera\u00e7\u00e3o subterr\u00e2nea, a minera\u00e7\u00e3o a c\u00e9u aberto tamb\u00e9m tem tr\u00eas grandes desvantagens: (1) Os \"tr\u00eas res\u00edduos\" no processo de minera\u00e7\u00e3o s\u00e3o f\u00e1ceis de destruir o meio ambiente; (2) \u00c9 necess\u00e1rio remover e descarregar uma grande quantidade de res\u00edduos de rocha, especialmente em minas a c\u00e9u aberto, e ocupar muitas terras agr\u00edcolas ou montanhas; (3) Afetada por condi\u00e7\u00f5es clim\u00e1ticas, como frio intenso, gelo, neve, calor extremo, chuva forte etc., afetar\u00e1 a efici\u00eancia do trabalho. Portanto, as vantagens da minera\u00e7\u00e3o subterr\u00e2nea incluem principalmente os seis aspectos a seguir: (1) Alta taxa de recupera\u00e7\u00e3o. (2) Baixa taxa de dilui\u00e7\u00e3o. (3) A carga de trabalho da minera\u00e7\u00e3o \u00e9 pequena. (4) A profundidade da minera\u00e7\u00e3o \u00e9 grande. (5) Menor investimento inicial. (6) Menor polui\u00e7\u00e3o do ambiente atmosf\u00e9rico.<\/p>\n\n\n\n

Parte tr\u00eas: como escolher um m\u00e9todo de minera\u00e7\u00e3o<\/strong><\/h2>\n\n\n\n
\"\"<\/figure><\/div>\n\n\n\n

Os benef\u00edcios econ\u00f4micos da mina s\u00e3o o fator decisivo.<\/strong><\/h3>\n\n\n\n

Suponha que voc\u00ea possa selecionar o m\u00e9todo de minera\u00e7\u00e3o ideal, o que far\u00e1 com que voc\u00ea obtenha os maiores benef\u00edcios econ\u00f4micos. Ao contr\u00e1rio, se o m\u00e9todo de minera\u00e7\u00e3o for selecionado incorretamente, isso afetar\u00e1 os indicadores t\u00e9cnicos da produ\u00e7\u00e3o da mina e os benef\u00edcios econ\u00f4micos por um longo tempo. As pessoas talvez pensem que a minera\u00e7\u00e3o em tiras \u00e9 mais segura. Ainda assim, para um empres\u00e1rio do setor de minera\u00e7\u00e3o que deseja maximizar os benef\u00edcios obtidos pela mina, com a inova\u00e7\u00e3o cont\u00ednua dos equipamentos e da tecnologia de minera\u00e7\u00e3o subterr\u00e2nea, a minera\u00e7\u00e3o subterr\u00e2nea ser\u00e1 considerada a primeira op\u00e7\u00e3o.<\/p>\n\n\n\n

Seguido pelo limite de profundidade da minera\u00e7\u00e3o<\/strong><\/h3>\n\n\n\n

O processo de minera\u00e7\u00e3o de tiras \u00e9 simples. Voc\u00ea s\u00f3 precisa usar m\u00e1quinas de minera\u00e7\u00e3o para minerar na superf\u00edcie e, \u00e0s vezes, a rocha de min\u00e9rio pode ficar exposta na superf\u00edcie. No in\u00edcio da minera\u00e7\u00e3o, voc\u00ea deve usar a minera\u00e7\u00e3o subterr\u00e2nea, como o m\u00e9todo de minera\u00e7\u00e3o em campo aberto, o m\u00e9todo de minera\u00e7\u00e3o em pilares, o m\u00e9todo de minera\u00e7\u00e3o em cavernas etc.<\/p>\n\n\n\n

As condi\u00e7\u00f5es de ocorr\u00eancia do dep\u00f3sito de min\u00e9rio<\/strong><\/h3>\n\n\n\n

A ocorr\u00eancia do corpo de min\u00e9rio geralmente afeta o m\u00e9todo de minera\u00e7\u00e3o da mina. Portanto, depende da espessura do corpo de min\u00e9rio e do \u00e2ngulo de inclina\u00e7\u00e3o em rela\u00e7\u00e3o \u00e0 dire\u00e7\u00e3o vertical, etc. Por exemplo, um corpo de min\u00e9rio fino com um \u00e2ngulo de inclina\u00e7\u00e3o maior que 55\u00b0 e a rocha ao redor \u00e9 moderadamente est\u00e1vel. O corpo de min\u00e9rio \u00e9 relativamente regular, o min\u00e9rio n\u00e3o se aglomera e n\u00e3o h\u00e1 nenhum fen\u00f4meno n\u00e3o natural. Nesse momento, \u00e9 melhor usar o m\u00e9todo de minera\u00e7\u00e3o de manuten\u00e7\u00e3o de min\u00e9rio.<\/p>\n\n\n\n

O significado do meio ambiente nos m\u00e9todos de minera\u00e7\u00e3o \u00e9 um motivo importante.<\/strong><\/h3>\n\n\n\n

A minera\u00e7\u00e3o, especialmente a minera\u00e7\u00e3o em tiras, resultou na destrui\u00e7\u00e3o ou ocupa\u00e7\u00e3o de grandes \u00e1reas de terra. O colapso da terra ao redor, o sistema de \u00e1guas subterr\u00e2neas e a perda de vegeta\u00e7\u00e3o causaram uma s\u00e9rie de problemas ecol\u00f3gicos, econ\u00f4micos e sociais, que se tornaram um grande problema enfrentado atualmente. Portanto, se o ambiente ecol\u00f3gico ao redor da mina for ruim, \u00e9 melhor optar pela minera\u00e7\u00e3o subterr\u00e2nea.<\/p>\n\n\n\n

Especialmente a seguran\u00e7a da minera\u00e7\u00e3o \u00e9 alta.<\/strong><\/h3>\n\n\n\n
\"caminh\u00f5es<\/figure><\/div>\n\n\n\n

Minha seguran\u00e7a \u00e9 sempre uma quest\u00e3o vital. Embora a minera\u00e7\u00e3o a c\u00e9u aberto seja mais segura do que a subterr\u00e2nea, com o r\u00e1pido desenvolvimento da tecnologia e dos equipamentos de minera\u00e7\u00e3o subterr\u00e2nea, a seguran\u00e7a da minera\u00e7\u00e3o subterr\u00e2nea melhorou dezenas de vezes em compara\u00e7\u00e3o com dez anos atr\u00e1s. Enquanto isso, a Fucheng, fabricante de equipamentos de minera\u00e7\u00e3o subterr\u00e2nea, oferece muitas m\u00e1quinas de minera\u00e7\u00e3o subterr\u00e2nea eficientes, que podem atender \u00e0 sua solicita\u00e7\u00e3o de seguran\u00e7a na mina.<\/p>\n\n\n\n
