Drilling rate prediction of an open pit mine using the ...

Drilling and blasting play vital roles in open pit mining. These operations do not only affect the cost of production directly but as well the overall operational costs [1]. The penetration rate prediction is a necessary value for the cost estimation and the planning of the project. For instance, the knowledge of penetration rate equation in a mine and classification of all the zones based on ...

Mining of Iron Ores – IspatGuru

14/03/2014  Drilling in the benches of open pit mining is done for production of iron ore with mechanized drills specific for each mining method. The main objective of drilling operations is to create a hole of suitable diameter, depth and direction in rock for explosives to be placed for blasting activities. The drilling of the holes is done normally in a particular pattern which depends on the bench ...

Blast Hole Drilling: The Basic Process RPM Drilling

Blast hole Drilling is a technique used in mining whereby a hole is drilled into the surface of the rock, packed with explosive material, and detonated. The aim of this technique is to induce cracks in the inner geology of the surrounding rock, in order to facilitate further drilling and associated mining activity. The initial hole into which the explosives are packed is known as the “blast ...

Reading: Open-Pit Mining Geology - Lumen Learning

Open-pit mining, or open-cast mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow. This form of mining differs from extractive methods that require tunneling into the earth, such as long wall mining. Open-pit mines are used when deposits of commercially useful minerals or rocks are found near the surface; that is, where ...
