Mining - Suppose coal is present at depth of 1000ft. So, in order to remove coal from subsurface what we do is remove the overburden strata or the matrix present above coal. This process is called mining. Mostly Solids like Coal, Metals etc are re...

Dec 16, 2019· Things Geologists Do. Part Something. Mine geologists –whatever their species, open pit or underground- will eventually end up supervising drill machines. Open pit mine geologists rely heavily on sampling the cuttings produced by production blast hole rigs. The assay results help to map the average grade of the ore before it's mined and sent to .

This research was carried out to find a possible way of optimizing the drilling and blasting operations in an open pit mine of Somair (Société des Mines de l'Air), in the Niger Republic. In order to opti- mize the drilling operation, the time taken by two drilling machines to accomplish the same task was analyzed statistically.

Open-pit mining methods are applicable to mining ore deposits that apex at or near the surface. If the deposit apexes below the surface, the overburden and barren capping overlying the ore must be removed in advance of open-pit mining. The removal of this material is known as stripping. The stripping-pit limits must be extended beyond the limits of the ore pit to provide a bench, and the pit ...

Dec 13, 2018· It is the most common drilling technique used for mining exploration, particularly in South America and Australia. RC drilling is a form of percussion drilling, by which the rock is made to fail through the use of a piston that delivers rapid impacts to the drill stem, transferring energy to the drill bit.

When it comes to surface mining equipment, no one has more experience helping miners match the right product to a specific need than . Ranging from dozers, drills and draglines to trucks, shovels, loaders and a host of support equipment, our .

Apr 07, 2014· Drilling in mining 1. Introduction to Drilling Technology for Surface Mining Prof. K. Pathak Dept. of Mining Engineering, IIT, Kharagpur-721302 1 Introduction Drilling is the process of making a hole into a hard surface where the length of the hole is very large compared to the diameter.

For instance, the ROC L8 is only 2.5 m wide, it can drive on the berm and also drill sideways at an angle of 32 degrees or more. Versatility = accuracy As the stability of the rock in an open pit mine determines the slope angle, and stability can vary from area to area, the resultin-g slope angles for the pit wall are not always in round figures.
