The importance of powder factor has been of immense importance in the field of fragmentation by blasting. Quick, accurate powder factor measurement is essential for any mining project. The fragment size of the muck pile plays an immense role in productivity because heavy machinery is deployed to load this muck pile, and it depends …
A large number of data from Indian surface mines were generated and used to verify the existing relations and to recommend the most suitable blasthole diameter for a given bench height.
The bench height in open pit mines will usually range from 15 m in large mines (e.g., copper) to as little as 1 m in small mines (e.g., uranium) ... the Brazilian mining company "Vale" has recently replaced its mine trucks with 23 miles of conveyor belts at its iron ore mine, linking the ore deposits to the company's processing ...
In metal mines, the amount of ore is usually expressed in either metric tons (1000 kg) or short tons (2000 lb). ... Where, H is bench height. Hence, ...
Dilution versus bench height (Bozorgebrahimi et al., 2005). Figure 3. Large block of the simple sequencing method. In open pit mining, factors that can affect the degree of dilution can be regarded as deposit-related or minerelated. The bench height is a mine-related parameter that can be studied using a simple geometrical model of the deposit.
Determination of practical bench height is an important subject in open pit mining. This subject has always been an issue with different and sometimes conflicting criteria that have to be...
slope design parameters are bench height, overall slope angle and area of failure surface. Stability of slope decreases with increases in height and slope angle. The overall angle …
