The overburden is drilled and blasted loose over an area above the oil shale zone and the load is then transported to a disposal area. Once the shale beds are exposed from the blasting, the shale is then drilled and blasted and then extracted from the pit. View chapter Purchase book. Read full chapter.
1. Mining open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers. Dump trucks haul the rock to the primary crushers in the open pit or to the ore stockpiles from

This flowchart made of machinery icons explains or expresses in simple but clear terms the step of the Copper Mining and Copper Extraction Process Starting from either open pit or underground mining and using a different relevant treatment method for oxide or sulphide copper mineral (ore)
To create an openpit mine, the miners must determine the information of the ore that is underground. This is done through drilling of probe holes in the ground, then plotting each hole location on a map. The information gained through the holes with provide an idea of the vertical extent of the ore''s body.
Jan 23, 2012#0183;#32;Step #5 Building Infrastructure. Before any mining can take place, infrastructure like roads and processing facilities must be constructed. Even the simplest openpit mines can take up to a year to construct before any mining can occur.
Openpit mining, also known as opencast mining, opencut mining, and strip mining, means a process of digging out rock or minerals from the earth by their elimination from an open pit or borrow. Toggle navigation Great Mining
For minerals that happen deep underneath the surfacewhere the overstrain is solid or the mineral happens as veins in hard rock underground mining methods take out the precious material. Openpit mines that manufacture building materials and dimension stone are usually referred to as quarries.

This bulk underground mining method involves mining large amounts of material from a single stope similar to cut and fill, this method starts at the bottom of a level and moves upward. Ore is removed from the bottom, and then more ore is blasted from a higher level that falls to the same level to be removed, with the process repeating up the orebody.
Jul 10, 2019#0183;#32;While both underground and openpit mining is widely accepted mining processes, there is a greater inclination to further expand underground mining. This transition from openpit to underground begins when openpit mines are exhausted or inaccessible; meaning, they have either been depleted of minerals, rocks, and resources, or they are unfeasible to build upon.
Underground mines are the alternative to surface mines. Surface mines excavate from the top down, a method that can become inefficient at depths greater than about 200 feet (60 meters) [sources: Illinois Coal Association, De Beers].Undergrounds coal mines can drive 2,500 feet (750 meters) into the Earth and other types even deeper uranium mines can reach 6,500 feet, or 2 kilometers.
A haul road is dug at the side of the pit to form a ramp for orecarrying trucks to haul material to and from the mining site. After the physical mine infrastructure has been built, production activities include drilling, blasting, excavation, loading and transporting broken ore.
Openpit mining, or opencast 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. Openpit mines are used when deposits of commercially useful minerals or rocks are found near the surface; that is
A significant amount of monitoring takes place in and around the open pit, to keep a watchful eye on: Slope stability and dewateringinduced settlement; Noise, dust and vibration; Water levels and water quality, including pit wall runoff and groundwater; Underground. Underground mines are used to extract minerals or metals from deep in the Earth.
GOING UNDERGROUND. Miners, mining materials and equipment are transported deep underground via the mine cage in the vertical shaft, which can go to depths of up to below the surface. Openpit gold mining also takes place in South Africa. This is a mining technique which
In openpit mining waste is transported to a disposal site, and the ore is transported to a downstream processing site. This method commonly involves a sequence of benches from the surface to the deposit. As the open pit goes deeper into the ground, all of the benches above are extended outward.
Underground sinking a vertical shaft into the earth to reach the copper ore and driving horizontal tunnels into the ore. Openpit 90% of ore is mined using the open pit method. Ores near the surface can be quarried after removal of the surface layers.
Mar 13, 2012#0183;#32;What is Opencast Mining Opencast mining is also known as Open pit mining, Open cut Mining, Surface or Strip Mining. The coal upto economical depth will be excavated by OC Method. The current operating depth of OC mines in SCCL is about 200m and SCCL proposed to operate OC mines upto a depth of 420m.
