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 overburden (if needed), stripping, removal of the coal or other mineral commodity, and reclamation.
A strip ratio, or stripping ratio, is an important measurement related to the openpit mining process. It represents the amount of waste material, also known as overburden, that must be moved in ...
The dragline operators became skilled at selecting overburden for building the spoil piles. In spite of all efforts to improve the situation, the unstable spoils would very frequently cover up the ore resulting in low ore recoveries, low production rates, and high mining costs. Next, bucket wheel excavators were carefully reviewed.
Jul 21, 2017· Overburden Removal Surface Mining 1. Overburden Removal GEORGE E. AIKEN JOHN W. GUNNETT GENERAL OVERVIEW Any evaluation of a specific need for overburden removal requires that the engineer first be aware of the various des ignations ofoverburden, the stateoftheart removal systems, and methods to transport these materials to permanent dep osition areas.

Openpit mining methods are applicable to mining ore deposits that apex at or near the surface. If the deposit apexes below the surface, the overburden and barren capping overlying the ore must be removed in advance of openpit mining. The removal of this material is known as stripping.
of mining companies will be able to conclude that their current accounting is completely in line with the interpretation. Following adoption of this interpretation, we expect greater consistency between companies in the treatment of production stripping costs. However, there is .
c. The operator has the option of providing separate topsoilstripping maps or placing the stripping depths on the topsoil survey maps. If the single map set is chosen the mine plan should clearly reference this fact. The symbolism on the map should include mapping unit number or letter, soil phase, and stripping depth. For example:

Overburden Removal . Overburden removal is an activity that absolutely must be done on mining, especially in mining activities that use openpit mining system. Overburden removal activity is determined by the target in the production plan; the better the design in the stripping of overburden will give the better production plan targets.

The phosphate strip mining is accomplished by various methods of stripping the materials from the ground as illustrated above. The phosphate industry relies heavily on the dragline excavator to keep moving large amounts of overburden to mine the phosphate rock just beneath the surface.
disposal site away from the mining area. In the above case, overburden is deposited in the open pit adjacent to the seam being uncovered and reclaimed as mining progresses. The cycle of operations includes clearing vegetation, soil removal, drilling and blasting overburden, stripping, removal of coal or other mineral commodity, and reclamation.
The present invention relates to a combination of open cast strip mining and auger mining of thin seams of hydrocarbonaceous deposits. In this mining method, a first working pit is stripped to expose the deposit, the hydrocarbonaceous material extracted and the exposed deposit seam face of at least one highwall is auger mined. A second and successive working pits are opened parallel to but ...
Jul 25, 2018· In mining, stripping ratio or strip ratio refers to the ratio of the volume of overburden (or waste material) required to be handled in order to extract some tonnage of ore. For example, a 3:1 stripping ratio means that mining one tonne of ore wil...
