    Jan 25, 2018 Coal also serves as fuel in the extraction of iron from iron ore and for the production of cement. Due to a rise in demand for coal, many mining techniques have evolved to extract the fossil fuel. A large-scale mining of coal requires the use of draglines, trucks, conveyors, hydraulic jacks and shearers

    Historically, geophysical technique (magnetic) was first used in Sweden in the 17th century for prospecting iron ore (Reedman, 1979). Geophysical techniques gained more acceptability in the early 1923 (Gupter, 1986) because of exploration for crude oil. Relevance of Geophysics across the world is as a result of oil and solid mineral exploration

    Open pit mining refers to mining directly on the ground surface, thereby producing an open pit. This method is practical and cost-effective when the uranium ore is located near the surface (e.g., within 100 m). Underground mining and ISL methods may be considered for sites that have uranium ores at deeper depths

    ISL mining has environmental and safety advantages over conventional mining in that the ore body is dissolved and then pumped out, leaving minimal surface disturbance and no tailings or waste rock (World Nuclear Association, 2012). There is no ore dust or direct ore exposure to the environment and a lower consumption of water is needed in the

    Open Pit Mining. Open-pit mining, also known as opencast mining, open-cut 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. The word is used to distinguish this type of mining from extractive methods that need tunneling into the earth

    Start by making a staircase down until you reach the level where the preferred ore is most generally found, and begin mining. Occasionally change directions and make numerous branches. If there is a rise, plow through it. If there is a fall, bridge it with cobble. OCD Mining This form of mining is reasonably simple. Find or make a cave

    Waste rock is piled up at the surface, near the edge of the open cut. This is known as the waste dump. The waste dump is also tiered and stepped, to lessen degradation. Ore which has been processed is called as tailings, and is normally slurry. This is pumped to a tailings dam or settling pond, where the water fades away
