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.
