Chapter Open Pit Mining

Open pit mining is widely used with metallic ore bodies (aluminum, bauxite, copper, iron), and nearly all nonmetallic (coal, uranium, phosphate, etc.). It is a traditional cone-shaped excavation (although it can be of any shape, depending on the size and shape of the ore body) that is used when the ore body is typically pipe-

Sublevel Caving Method with Sill Pillar | SpringerLink

Sublevel caving method with sill pillar is the mining process in which a level is divided into several sublevels, a bottom structure specifically used for ore removal is furnished at the lower part of each sublevel, and stoping of ore proceeds from the top sublevel to the bottom sublevel (Fig. 1).It is also called sublevel caving method with bottom structure.

The ore strength on the other hand is not quite as important in the choice of the method. As the ore strength declines, it will be necessary to leave larger pillars, and at some point, that becomes uneconomical. In real-world situations, however, the ore strength is rarely an important characteristic for the selection of this method.

the time periods of quarry exploitation. Ore mining is performed alternately in one of the sections. Mining operations begin in primary section I. During the first mining period T 1, the ore reserves of the first stage in this section are fully worked out by quarry. In the next period T 2, the ore reserves of the first stage of

Understanding Underground Mining Methods

Cut and fill mining is an underground mining method used to mine steeply dipping or irregular ore bodies. It is useful for mining at depths where surface support is unavailable. Cut and fill is a very selective method, which allows for high recovery rates, and it is typically used where the quality of the ore varies significantly, or to ...

Room-and-Pillar Mining Method

low hole room-and-pillar mining method is adopted for the ore body of the thickness less than 8 m. When the thickness of the ore body is 8–20 m, the medium-deep hole room-and-pillar mining method is adopted, and trackless equip-ment is used for ore drawing. The advantages of the room-and-pillar mining method are small mining load, simple ...

Digging deeper: Mining methods explained | Anglo American

Large scale mechanised mining methods we use include: long-wall mining, where a long wall of coal is mined in a single slice, usually by a large machine. sub-level-caving, where levels of the ore are blasted by explosives; and ; block caving, where large areas of the ore body are blasted and …

Optimization of room-and-pillar dimensions using

Room-and-pillar (R&P) mining is a method of extracting a series of rooms (i.e., long horizontal openings) while leaving behind pillars of ore, rock, or coal. In hard rock masses, pillar widths are smaller than entry widths. Pillars can be constituted solely of ore or of ore and waste when the ore body is thin.
