The miners spent more than two months there, getting food, air and letters from loved ones through bore hills drilled to their location in a protected workroom. Meanwhile, the larger-scale drilling of an escape shaft made slow progress. Finally, on Day 69, rescuers lifted each of the miner在science.howstuffworks上查看更多信息

    Surface mining can be used when the coal is buried less than 200 feet underground. In surface mining, giant machines remove the top-soil and layers of rock to expose large beds of coal.Once the mining is finished, the dirt and rock are returned to the pit, the topsoil is replaced, and the area is replanted.
