CHAPTER 1 ENGINEERING OF MINERAL EXTRACTION
Surface Mining. Surface mining is the removal of material from the earth in excavations that are open to the surface. In some cases, material is removed directly from the earth's surface; for example, sand and gravel may be removed directly from deposits of those materials put in place by ancient lakes or rivers.
