Mining is one of the oldest industries on Earth. Underground mining is used when mineralization is deep beneath the surface and/or when ore grade or quality is sufficient to justify more targeted mining. Deep-sea mining is attracting growing interest from mining companies and could begin in earnest in just a few years. In order to get to the ore body, a vertical shaft, horizontal adit, or inclined passageway must be drilled remove ore and waste and provide ventilation. Diamond mining is a feat which requires precision, care and a lot of hard work. Miners use heavy machinery to cut out the coal and rely on conveyor systems to transport the coal to the surface. A diamond mining process consists of locating possible diamond deposits and their retrieval, in intact form. The area actually being mined at any given time is called the face. Some mines can extend to depths of more than 1,000 feet.
Copper mining is a very complicated process made easier by today’s technology. The biggest copper mines are in Chile and North America, every year many thousands of tonnes of copper ore were produced, The copper ores are extracted by either traditional mining (open pit or underground) or by leaching, and 90 percent of the copper ore was mined from open pit.
Like coal mines, metal ore mines are found in both surface and underground varieties, depending on where the ore deposit is located. In addition to strip mining, surface ore mines also use the open-pit mining technique. These mines are huge holes in the ground that are mined by blasting rock from the sides and bottom with explosives, carrying out the broken up material in trucks, and then repeating the process.
