Throughout the world there are veritable fields of dangerous, exposed holes from mining operations that were simply abandoned after they stopped yielding minerals or coal. There are an estimated 100,000 to 500,000 abandoned mine sites in just the Western United States; the Bureau of Land Management (BLM) has identified and located 12,204 of those as of April 2008 [source: BLM ].

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

Iron ore is an element of the Earth's crust, and the continuous mining causes its depletion. The extraction of coal and emission of greenhouse gases lead to climate change and environmental degradation. The Top 10 Steel Producing Countries In The World

The globe's largest mining companies are enjoying boom times. Between 2017 and this year, the combined revenue of the 40 largest miners in the world has increased from $632 billion to $686 billion, while profitability (EBITDA) jumped by $11 billion to a total of $

Coal is either extracted from deep inside the earth or removed from its surface. The former is known as underground mining, the latter as strip mining or mountaintop removal. Either process contributes a high level of damage to the environment: #12 Noise pollution

The technique has many advantages over underground mining, including higher productivity, greater safety, and better recovery of in situ coal resources. It principal disadvantage, however, is the greater level of unfavorable impact, at least in the short term, on the surface environment and other land uses.

Coal is either extracted from deep inside the earth or removed from its surface. The former is known as underground mining, the latter as strip mining or mountaintop removal. Either process contributes a high level of damage to the environment: #12 Noise pollution

Strip mining accounts for about 40 percent of the world's coal mines but in some countries, such as Australia, open cast mines make up 80 percent of mines. Even though it's highly destructive, industry often prefers strip mining as it requires less labour and yields more coal than underground mining.

Surface mining can be used when the coal is buried less than 200 feet underground. In surface mining, giant machines remove the top-soil and layers of rock to expose large beds of coal. Once the mining is finished, the dirt and rock are returned to the pit, the topsoil is replaced, and the area is replanted.

It also provides an international exchange forum for the readers and authors all over the world engaging in mining sciences and technologies. Papers to be published will be peer-reviewed and rigorously edited by specialists and authorities.
