<p><br /> A video has been released showing footage taken inside the mine in which 33 miners remain trapped underground.<br /> </p><p><br /> The miners can be seen playing cards and singing the Chilean national anthem.<br /> </p><p><br /> Several miners sent messages to their families and to rescue workers above ground.<br /> </p><p><br /> "It takes courage to not leave us abandoned. We know everything you've been doing outside," said one.<br /> </p><p><br /> Fresh clothes, medicine and games are being sent down a 700 meters bore hole the diameter of a grapefruit.<br /> </p><p><br /> The government has asked Nasa and Chile's submarine fleet for tips on survival in extreme, confined conditions, and are looking to send them space mission-like rations.<br /> </p><p><br /> A second narrow bore hole has been drilled - dedicated to channeling drinking water to the miners and keeping communications flowing.<br /> </p><p><br /> They are also preparing to drill a vertical shaft around 2 feet in diameter to evacuate the miners one by one via a pulley.<br /> </p><p><br /> Health officials have said the miners can expect a period of depression and anguish, after the initial euphoria of being found passes, but health minister Jaime Manalich said the miners had reacted calmly after learning there would be a long wait before they saw the light of day.<br /> </p>
