Localiza\u00e7\u00e3o do caso: Mina de carv\u00e3o Shenmu Shenhua Shendong<\/p>\n\n\n\n

O processo de corte port\u00e1til e compacto por jato de \u00e1gua de alta press\u00e3o \u00e9 um corte limpo e a frio, sem risco de explos\u00e3o ou inc\u00eandio. O corte por jato de \u00e1gua de alta press\u00e3o (tamb\u00e9m conhecido como corte hidr\u00e1ulico) \u00e9 extremamente eficiente, pois n\u00e3o gera calor, tens\u00e3o ou distor\u00e7\u00e3o nos materiais. A m\u00e1quina de corte de chapas de a\u00e7o e concreto por jato de \u00e1gua abrasivo port\u00e1til de alta press\u00e3o \u00e9 amplamente utilizada para corte de furos em tanques de res\u00edduos, corte de tubula\u00e7\u00f5es de g\u00e1s, corte de linhas de interse\u00e7\u00e3o e perfis, e corte de chapas, entre outros.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Nosso caso \u00e9 o de escava\u00e7\u00e3o em minas de carv\u00e3o. Devido \u00e0 alta press\u00e3o e ao rompimento do teto durante a escava\u00e7\u00e3o de t\u00faneis em minas de carv\u00e3o, geralmente s\u00e3o utilizadas barras de ancoragem para sustentar o teto do t\u00fanel e cabos de ancoragem para refor\u00e7\u00e1-lo. Na produ\u00e7\u00e3o de escava\u00e7\u00e3o em minas de carv\u00e3o, os cabos de ancoragem s\u00e3o usados com frequ\u00eancia, e sua remo\u00e7\u00e3o \u00e9 muito dif\u00edcil. Diante da atual situa\u00e7\u00e3o de alto risco de rompimento de cabos de ancoragem em minas de carv\u00e3o subterr\u00e2neas, da grande demanda por servi\u00e7os de corte e da baixa efici\u00eancia, nossa empresa e a Shenhua [nome da empresa] desenvolveram um projeto conjunto.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n
\"\"<\/figure>\n\n\n\n

O grupo cooperou para desenvolver equipamentos de corte com \u00e1gua de baixa press\u00e3o de pequeno porte, adequados para minas de carv\u00e3o subterr\u00e2neas.<\/p>\n\n\n\n

O local desta demonstra\u00e7\u00e3o de corte \u00e9 uma f\u00e1brica de minera\u00e7\u00e3o de carv\u00e3o do Grupo Shenhua, e \u00e9 necess\u00e1rio para ancorar o t\u00fanel.<\/p>\n\n\n\n

A parte exposta do cabo \u00e9 cortada para concluir a remo\u00e7\u00e3o do palete do telhado. Cabo de ancoragem a ser cortado.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

O di\u00e2metro da ferramenta \u00e9 de 7 a 9 cm e o di\u00e2metro do cabo de a\u00e7o \u00e9 de 2 a 4 cm. Esta demonstra\u00e7\u00e3o utiliza a ferramenta especial desenvolvida pela nossa empresa para corte de cabos de ancoragem, que adota um m\u00e9todo de corte oscilante a partir da base do cabo de ancoragem, cortando o cabo de a\u00e7o, removendo em seguida a \u00e2ncora e o cabo de a\u00e7o e, finalmente, removendo a \u00e2ncora.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Desmonte o disco e conclua toda a tarefa de corte.<\/p>\n\n\n\n

Ap\u00f3s in\u00fameros testes, comprovou-se que o uso da tecnologia port\u00e1til de corte a \u00e1gua permite realizar opera\u00e7\u00f5es de corte de cabos de ancoragem em minas de carv\u00e3o de forma mais segura e eficaz, reduzindo a intensidade do trabalho dos oper\u00e1rios e os riscos ocupacionais.<\/p>\n\n\n\n
