        "http://www.w3.org/2000/01/rdf-schema#comment" : [ "Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed. It is the opposite of underground mining, in which the overlying rock is left in place, and the mineral removed through shafts or tunnels.Surface mining began in the mid-sixteenth century and is practiced throughout the world, although the majority of surface mining occurs in North America." ] ,
