1.
Surface mining is the process of excavating mineral deposits directly from the surface of the ground without costly shafts or tunnels into the earth.
露天采矿就是不用在地下挖掘费用高昂的井巷而直接从地表采矿的方法。
2.
Surface mining is only used when the mineral deposit lies near the surface of the ground. For those buried deep in the ground, underground mining is used instead.
露天开采只是在矿床靠近地表时才使用。对深埋在地下的矿床，采用地下开采。
