Coal, geological materials and minerals found in the underground rocks such as sedimentary rocks are extracted using mining process. There different types of minerals located in different areas and require specific underground mining parts. These places either contain nickel, tin, gold, iron, lead or even silver. The key mining activities involve use of shafts to excavate ores.
Underground mining can be done using different methods which is determined by size, orientation, type and shape of ore. Cut and fill method is used in steep dipping ores. It is limited to use of methods that have long hole. Drift and fill are used to drill wider zones of ores ensuring that the zones are fully mined.
Both shallow and deep mines are good for mining. This guarantees you of getting minerals of high value. Gold is mined in depths that are in the lower levels of the underground rocks. Depth that exceeds 3900 meters is the most favorable for uranium extraction which is always found in hard rocks. Deep excavating methods are favorable for minerals that are of high value. These minerals are located in the walls of the cave and in large amounts. This ores are in open stopes that favor extensive extraction.
There deep methods used in mining of coal, boreholes are used to recover minerals from the ground surface. The excavating is done once the minerals are found in deep areas beyond economic depth such as open pits. Thin deposits require relatively high capital to remove the minerals in slopes. Open pit mining is one of the methods that are done by use of a shaft. The shaft is used to reach the ore-body.
Raising the minerals upwards is done using drifts and some upward passages. To get to the lowest levels of mines you need the shafts to be dug downwards. Pumping, ventilation and haulage are ways of getting pillars of ores that are lying between the stopes. Unmined minerals are left in the stopes and allow excavation once extracting starts. Large scale extraction breaks the ores into small blocks, panels or slices.
Sampling, drilling and rock testing are used in to explore bulk deposits. Blind tunnel is used to cut the minerals deposits. Multipurpose shafts are used to drill large mines. These large mines are arrived at by use of inclining and declining portals. Strong ores are extracted using methods that are of high cost while weak ores are extracted using low cost methods. Rock bolting is one of these equipment that makes the method expensive.
There are various phases used in underground extraction. There is exploration and feasibility phase, mine operations phase, construction and planning phase together with the closure phase. The activities involved include drilling, crushing, grinding, ore separation and concentrate dewatering. Rock piles are separated in stages while water is separated in stages to. The operation also include extraction and processing of the ore.
At the head is the shaft which acts as the elevator. There is the sump sits which have several channels that run horizontal so as to reach at the ore-body. The mineral containing materials are in different levels . Here we get ramps are used to access these minerals.This parts are inclusive of crusher and drifter that help in digging the rocks located in deep areas.
