· Surface Mining Surface mines are mining operations that delve into rock to extract deposits of mineral resources that are close to the surface . In most forms of surface mining, heavy equipment, such as earthmovers, first remove the overburden (the soil and rock above the deposit). Next, huge machines such as drag line excavators extract the mineral. Once the
