Sutro Tunnel
http://dbpedia.org/resource/Sutro_Tunnel an entity of type: Thing
El Túnel Sutro (en inglés: Sutro Tunnel) es una galería de 6,2 km de longitud construida para drenar las minas de plata de la veta Comstock. Situado en el oeste de Nevada (Estados Unidos), el túnel tiene su única boca unos 5 km al norte de la ciudad de Dayton, y termina aproximadamente 6 km al oeste-noroeste, a unos 500 m por debajo de la ciudad de Virginia City.

Le tunnel de Sutro est un tunnel de drainage minier de six kilomètres de long, sans compter les puits d'aération et les galeries transversales, situé sous le gisement aurifère et argentifère de Comstock Lode dans le Nevada, non loin de la ville de Virginia City. Creusé de 1869 à 1878 par l'ingénieur allemand Adolph Heinrich Joseph Sutro (1830 – 1898), il a permis l'aération des galeries et l'irrigation des terres agricoles environnantes, par l'eau de la montagne ainsi drainée.

The Sutro Tunnel is a drainage tunnel (adit) connected to the Comstock Lode in Northern Nevada. It begins at Dayton, Nevada and connects 3.88 miles (6.24 km) Northwest to the Savage mine in Virginia City, Nevada. The tunnel was proposed by Adolph Sutro, a Prussian Jewish mining entrepreneur, in 1860. He promoted the drainage tunnel to allow access to deeper mineral exploration in the Comstock. Flooding and inadequate pumps had inhibited some exploration until that time. Arthur De Wint Foote worked on the tunnel in 1873, but was fired in 1874, having struck a flood of water in Shaft No. 2.

O Túnel Sutro é um túnel de drenagem (ádito) ligado ao no norte do estado do Nevada. Começa em Virginia City e termina a cerca de 10 quilómetros a sudeste [1] próximo da vila de Dayton). O túnel foi pela primeira vez "visionado" por em 1860. Ele promoveu o túnel de drenagem a fim de permitir o acesso mais fundo da exploração mineral no Comstock. A inundação das minas e bombas inadequadas inibiram algumas atividades de exploração naquela época.

The Sutro Tunnel is a drainage tunnel (adit) connected to the Comstock Lode in Northern Nevada. It begins at Dayton, Nevada and connects 3.88 miles (6.24 km) Northwest to the Savage mine in Virginia City, Nevada. The tunnel was proposed by Adolph Sutro, a Prussian Jewish mining entrepreneur, in 1860. He promoted the drainage tunnel to allow access to deeper mineral exploration in the Comstock. Flooding and inadequate pumps had inhibited some exploration until that time. By 1865, Sutro's idea had gained the approval of state and federal governments. The mining interests of the Comstock initially supported the project, but later opposed the idea. They feared that an alternate access point to the Comstock minerals would threaten their monopoly on the mining and milling of gold and silver in the Comstock. Nonetheless, Sutro formed the Sutro Tunnel Company, selling stock certificates to raise funds for its construction, which began in 1869. Financing also came from local miners motivated by the prospect of improved mine safety. This motivation was further advocated by Sutro after the Yellowjacket mine disaster where dozens of miners were burned to death because they could not escape. Arthur De Wint Foote worked on the tunnel in 1873, but was fired in 1874, having struck a flood of water in Shaft No. 2. The main tunnel connected to the Savage Mine in 1878, the North and South branches were completed in 1879. Water was released from the mines on June 30th of 1879. Upon completion, Adolph Sutro sold his interest in the tunnel company, stayed on as a board member and moved to San Francisco, later becoming mayor, building the Sutro Baths and much more. Adolph's brother Theodore Sutro then took over control of the Sutro Tunnel Company until 1894 when he then sold it to Franklin Leonard Sr. The Sutro Tunnel pioneered the excavation of large drainage and access tunnels in the US. Later US mine drainage tunnels included the Argo Tunnel at Idaho Springs, Colorado, the Leadville and Yak tunnels at Leadville, Colorado, and the Roosevelt tunnel in the Cripple Creek district, Colorado. The "Friends of Sutro Tunnel" are working to preserve this significant part of Nevada's mining history by restoring the Sutro Tunnel Site. The goal of the project is to not only preserve the site's historical integrity, but to also make it safe and accessible for visitors. Phase One of the project is currently underway with the focus being on ongoing site cleanup and protecting remaining structures from further deterioration.

O túnel foi pela primeira vez "visionado" por em 1860. Ele promoveu o túnel de drenagem a fim de permitir o acesso mais fundo da exploração mineral no Comstock. A inundação das minas e bombas inadequadas inibiram algumas atividades de exploração naquela época. Por volta de 1865, a ideia de Sutro obteve a aprovação da legislação estatal e federal. Os interesses mineiros também apoiaram de início o projeto do túnel, mas mais tarde opuseram-se à ideia. Ele temiam que um acesso alternativo à mina Comstock ameaçariam o seu monopólio da mineração e trituração do ouro e prata na referida mina. Todavia, Sutro fundou a Sutro Tunnel Company, vendendo para aumentar os fundos para a sua construção que se iniciou em 1869. O financiamento para a construção do túnel também veio de mineiros locais.O projeto foi mais advogado por Sutro depois de um desastre da mina de Yellowjacket onde dezenas de mineiros morreram queimados porque não tinham forma de escapar da mina. trabalhou no túnel in 1873, but was demitido em 1874, depois de ter ocorrido uma infiltração de água no Shaft No. 2. Também foram construídos túneis laterais para aumentar a drenagem e a ventilação das minas. O seu criador vendeu as suas ações desde o fim dos trabalhos, em 1878 e depois partiu para San Francisco para investir no imobiliário, depois de se tornar presidente da câmara/prefeito daquela cidade.O principal túnel ficou completo em 1878.
