The Advantages of Open Pit Mining | Sciencing

Because an open pit mine is open to the air larger machinery can be used to operate the mine. This is a real advantage to mining companies who often use large trucks to carry debris away from the mine. According to Corporation the model 777 off road truck commonly use in open pit mines can carry a payload of 200,000 pounds.

Surface mining - Wikipedia

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, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.. Surface mining began in the mid-16th century [dubious
