    Strip mining, removal of soil and rock (overburden) above a layer or seam (particularly coal), followed by the removal of the exposed mineral The common stripmining techniques are classified as area mining or contour mining on the basis of the deposit geometry and type The cycle of operations for both techniques consists of vegetation clearing, soil removal, drilling and blasting of

  • What is Strip Mining? (with pictures) Info Bloom

    Strip mining is a type of surface mining which involves the removal of a thin layer of material known as an “overburden” to access buried deposits of useful minerals This type of mining is only effective in areas where mineral deposits are very close to the surface, making it feasible to quickly and easily remove the overburden to get to them Classically, strip mining is used to mine tar
