In openpit mining, in order to extract an ore block, it is necessary to remove all waste blocks with a variable slope angle up to the surface. The final combination of all ore blocks together with all waste blocks necessary to reach them that give maximum economic value is called UPL. Many studies have been carried out to determine UPL.

Lesson : Mechanical Surface Mining Methods Introduction Open Pit ...

Mechanical extraction methods employ mechanical processes in a relatively dry environment to mine minerals from the Earth's crust. In contrast, aqueous methods involve water, or occasionally other liquids, to extract minerals. The surface mining methods can be classified as shown here. We will discuss the mechanical extraction methods in this ...

Surface mining planning and design of open pit mining | PPT SlideShare

4. Although the basic concept of an open pit is quite simple, the planning required to develop a large deposit for surface mining is a very complex and costly undertaking. At one mine, it may be desirable to plan for blending variations in the ore so as to maintain, as nearly as possible, a uniform feed to the mill. At another operation it may be desirable to completely separate two kinds of ...

Easy profit maximization method for openpit mining

The profit function can also be formulated in unit values (per ton or cubic meter of ore), by assigning a unit profit function L ′ (/h), which is given by (2) L ′ = T U V − M − E R − B − F P. In all these variables, there are two geological characteristics, which have great importance: the stripping ratio R and the grade of ore is therefore essential to determine what their ...
