这是发生在非洲的一个真实的故事6名矿工在很深的地下采煤突然，矿井倒塌，出口被堵住，矿工们顿时与外界隔绝凭借经验，他们意识到自己面临的最大问题是缺乏氧气，如果应对得当，井下的空气最多还能维持3个半小时外面的人一定已经知道他们被困了，在空气用完之前他们能获救吗? This is a true story of what happened in Africa. Six miners plunged into deep underground coal Suddenly, the mine collapsed and the exit was blocked. The miners were immediately isolated from the outside world. Based on their experience, the biggest problem they realized was their lack of oxygen If properly dealt with, the downhole air can last for up to three and a half hours. People outside must already know that they are trapped and can they be rescued until the air runs out?
