Dec 08, 2018· Mining involves the extraction of valuable minerals from the earth surface. Mining can either be surface mining or sub-surface (underground) mining. Mining not only beneficial to the surrounding community and public in general, but it can also pose a lot of risks to the surrounding community. Let’s look at the pros and cons of mining
Apr 27, 2015· Historically speaking, underground mining not only saves the mining area’s original form but also gives the mining company higher revenues. According to MiningGlobal, longwall mining, a type of underground mining that utilizes a longwall shearer, accounts for 50 percent of coal mines in the world and is much safer than other methods of coal mining.

Since cyanide, mercury and sulfuric acid are used to remove the wastewater, groundwater and air are contaminated as toxic dust . This is absorbed by animals and plants.
Materials such as coal and tar sand are located relatively near the surface of the earth. The method to recover such materials is called strip mining, a form of surface mining where surface vegetation, soil and rocks are removed in strips and often times together with controlled explosions in order to make the removal process more efficient.
4. Disadvantages of open pit mining. However, disadvantages when compared to Underground Mining also exist: Very large amounts of waste rock are mined. This creates costs as well as environmental issues with waste rock disposal; Major disruption of surface: pit footprint, waste dumps. High visual impact, especially strip mining.
2. Surface Mining Machinery Glossary Bibliography Biographical Sketches Summary This chapter deals with surface mining. Section 1 presents an overview of surface mining methods and practices as commonly employe d in modern surface mining operations. The description includes a comparison of the advantages and disadvantages of surface and
Feb 25, 2015· For those who are unfamiliar, strip mining is a form of surface mining that focuses on the collection of tar sand and coal, which both rest somewhat close to Earth’s surface. Those who support strip mining point to the increased ease of access and all of its attendant benefits. Detractors point to the controversies surrounding this method.
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).
Apr 25, 2017· Mining is the extraction of minerals and other geological materials of economic value from deposits on the Earth. Mining adversely affects the environment by inducing loss of biodiversity, soil erosion, and contamination of surface water, groundwater, and soil. Mining can also trigger the formation of sinkholes.

Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes. These processes also have an impact on the atmosphere from the emissions of carbon which have
Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels..

Various mining processes are used to harvest coal from its underground deposits, but only two methods are primarily used: deep mining (underground) and surface mining (opencast). More than 7.2 billion tons of hard coal are currently produced annually through these mining methods.
THE IN-SITU ADVANTAGE. Smaller footprint: The surface area required for the wellheads and central processing plant is very small relative to the size of the oil sands deposit.In-situ facilities therefore have a much smaller footprint than surface mining operations. In-situ plants require about 1/7th the land area of an equivalent-sized mining facility.
