This practice requires that one or more main ore passes be provided for transferring the ore from the intermediate or ore-extraction levels to the haulage level below. The position of these passes will obviously be determined by the relative positions of the ore bodies, intermediate levels and shafts, or other main outlets of the mine.

Mining - Prospecting, Exploration, Resources: Various techniques are used in the search for a mineral deposit, an activity called prospecting. Once a discovery has been made, the property containing a deposit, called the prospect, is explored to determine some of the more important characteristics of the deposit. Among these are its size, shape, orientation in space, …
The intervals between ore passes should not exceed 500ft, or 150m. Ore pass inclination should be maintained between 45° and 90°, while ore pass length should be in the range of 10m to 300m.

The ore is drawn by raising one or more of the stopboards. The form shown at C is a cleated chute and that at D is of the simplest bracket-supported construction. The latter was employed at the Ahmeek mine in Michigan, where the ore was mined in flat-dipping open stopes and the back stands well, requiring little support along haulageways.

The ore-skin design has already been implemented in different mining operations around the world and was shown to be successful at achieving reduced dilution rate .8, 9, 10 By leaving an appropriate thickness of unmined ore along the HW, one can achieve reduced dilution rate; however, the mining recovery is also reduced.
Open-pit mining remains the dominant method for copper extraction in current operations, with blasting playing a pivotal role in the efficiency of downstream processes such as loading, hauling, crushing, and milling. This study assesses the impact of surface blast design parameters on the performance of a comminution circuit processing a copper-bearing ore.

The design of mining enterprises begins with numerous studies, including the determination of the mineralogical composition of the ore, the possibilities of its industrial processing, the analysis of market conditions and customer requirements, possible restrictions on …
When ore is first processed (typically close to the mine) it is crushed to gravel-sized chunks and then ground to a fine powder and the ore minerals are physically separated from the rest of the rock to make a …
Therefore, reserve efficiency is one of the factors in any sustainable mine design. Sustainable mining covers environmental, economical, and social aspect of operations. Different approaches are practiced for mine design selection such as NPV maximization, mine life maximization, and maximizing extracted ore value.
