  Advantages and disadvantages of open pit mining – .

  What is open pit mining . Open pit mines are those mining operations that take place on the surface, unlike the underground mines. This is possible when the reservoir sprouts on the surface or at a very small depth. It began to be realized in the middle of the XVI century and it is used all over the world.
