Open Pit Mining at Its Best
Open Pit Mining

Open-pit mining is a kind of surface mining. Mining companies choose this way to get rocks and minerals out of the ground because it is the easiest and cheapest way to do it. Open-pit mining is only used if the rocks or minerals are close to the surface of the land or if a normal tunnel-type of mine isn't possible.

The top layers of the land are removed. After that, layer after layer is taken away until the rock or mineral is visible. This is taken out, processed when it needs it, and sold. Taking away layer after layer of land creates a gigantic, open hole (or pit) that keeps getting deeper and deeper until there is nothing left to bring out. Explosives (like dynamite) are used when the miners want to get large blocks of materials out of the earth.

Most of the time, when the mining company is done with it, the pit is used as a landfill. A landfill is used as a dump to get rid of our garbage. When it is filled with garbage, it is covered over with layers of dirt. After the garbage rots a long time, the land can be used again.

Some examples of locations of open pit mining in Australia are:
(Super Pit) – gold mine near Kalgoorlie, Western Australia
(Cadia mine) – gold and copper mine located near Orange, New South Wales
(Boddington Gold Mine) – Boddington, Western Australia
(Telfer Mine) – Gold and copper mine in Pilbara, Western Australia
(Ranger Mine)– Uranium mine east of Darwin in the Northern Territory, Weipa, Queensland.

To get at the mineral, rocks and wealth just below the surface, the entire area needs to be stripped of all vegetation and natural animal habitats. For example, Brazil has some of the largest open pit mines in the world, which have been created by removing thousands of acres of rain forest, which sustained countless numbers of animal species.

Mining requires loads of machines to dig out the minerals, large trucks to take them away and further machines to process the resource. These all run on

    As seen from above, crucial planning needs to be done prior to opening the mine so that a profit will be made in the end. The total income received from selling the minerals need to be greater than all the costs involved. These costs include, the wages of the miners, surveyors and financial analyzers, the costs of the mining process itself including the clearing of land and digging, the costs of buying and running the vehicles and equipment and finally the costs of the environmental rehabilitation.…

    Bingham Canyon or commonly known as Kennecott Copper Mine is the world`s deepest man-made open pit mine for copper and gold, located near Salt Lake City, Utah. The mine is owned by Rio Tinto Group. According to “Top 10 Deep Open-pit Mines” article, since Bingham Canyon Mine started its operation in 1906, it has become the “granddaddy” of all copper mines with a diameter of 2.75 miles (4,5km) and a depth of 0.75 mile (1,2km). In fact, Bingham Canyon Mine is also called "the richest hole on Earth” for the average $1.8 billion dollars value production of metals produced annually (Arrlington & Hansen, 1963). However, despite being the largest copper mine the USA, it also produces a wide range of byproduct metals and waste rocks; approximately, “three billion metric tons” of waste…

    This destruction has a poor effect on the land cover of the area. Surface mining has led to large amounts of deforestation and the destruction of forests previously occupied by animal species. This destruction has occurred because of the need to clear the land to make room for the mine. In these cases it is unfortunate for the environment that it is often the mining and extraction of the minerals that take priority over the land. When mining harmful radioactive elements and metallic dust may be exposed and pose a threat. Even after mines close down and are no longer in use, the harmful pollutants often remain in the soil and the rivers remain contaminated with heavy metals. This continues to have an impact on the growth of plant life and the land cover of the site for many years to…

    Shaft mining – when gold started to become scarce just under the surface of the ground, miners turned to digging deep holes, or shafts, in the ground. These shafts would be approximately one meter squared and could be up to 50 meters deep. The miners would prop timber along the sides of the shaft to stop it from collapsing and would use a windlass or winch to bring up buckets full of…

    Essay On Coal Mining

    • 688 Words
    • 3 Pages

    The goal of coal mining is to obtain coal from the ground. Coal is valued for its energy content, and, since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United States, United Kingdom, and South Africa, a coal mine and its structures are a colliery. In Australia, "colliery" generally refers to an underground coal mine. Coal mining has had many developments over the recent years, from the early days of men tunneling, digging and manually extracting the coal on carts to large open cut and long wall mines. Mining at this scale requires the use of draglines, trucks, conveyor, jacks and shearers (definitions.net). A career in coal mining requires specific skills and training, offers common compensation and benefits, and has an expected career path and opportunity for advancement.…
