There are two basic ways to mine coal. Surface mining is used when coal is found close to the surface or on hillsides. This method essentially involves removing the overburden (earth and rock covering the coal) with heavy earth moving equipment, scooping out the coal, replacing the excavated soil and reestablishing vegetation and plant life, a ...
Dumpers or Tippers 9. Drag Line 10. Road Grader 11. Rock Drills. Opencast mining is the oldest method of excavating minerals but the mining operations have been mechanised by the use of heavy earth moving machinery during the last 50 years resulting in excavations on a scale which was unthinkable half a century ago.
