Strip mining | Britannica

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 strip-mining 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

Nov 14, 2014· The pit shells for the interim stages have a greater impact on NPV than the stages in later years of the mine life; therefore, optimum interim pit shell selection is vital for strategic planning success. Interim pit shells are not an input to the schedule, but rather an output of an automated scheduler which has all of the pit shell candidates

Strip Mining an overview | ScienceDirect Topics

Andrew P. Schissler, in Encyclopedia of Energy, 2004. 2.3 Strip Mining. Strip mining is employed in coal reserves where the overburden is removed in rectangular blocks in plan view called pits or strips. The pits are parallel and adjacent to each other. Strip mining is fundamentally different from contour or area mining on how the overburden is displaced, called spoil handling.

1.1.3.1 Open-pit mining Open-pit mining is a type of strip mining in which the ore deposit extends very deep in the ground, necessitating the removal of layer upon layer of overburden and ore. In many cases, logging of trees and clear-cutting or burning of vegetation above the ore deposit may precede removal of the overburden. The

Surface mining Wikipedia

Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.

Salt Production and Processing Morton Salt

Most mine shafts are lined with a concrete wall called a shaft liner. Salt is mined by the room and pillar method. It is removed in a checkerboard pattern to leave permanent, solid salt pillars for mine roof support. Usually 45 to 65 percent of the salt is removed. The room height may average 18 feet in a bedded deposit to 100 feet in a dome mine.

In conventional mining, the coal seam is cut, drilled, blasted and then loaded into cars. Continuous mining is the most prevalent form of underground mining, accounting for 56% of total underground production. In continuous mining, a machine known as a continuous miner cuts the coal from the mining face, obviating the need for drilling and

Two Decades of Mine Reclamation: Lessons learned from one

Federal mining laws were an impetus to this program. Reclamation of mine sites, and the posting of bonding by coal mine companies to guarantee reclamation, had been always required. But the size of the bonds and the details of their release to the coal companies increased after 1977. The release of bonds became a three-stage process.
