Coal mining is the process of extracting 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 Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is a 39pit39, and
COAL 115 Poland and South Africa maintain large amounts of coal exports, yet each nation does not account for even 1 of the world39s coal reserves.

Gold mining is the process of mining of gold or gold ores from the ground. There are several techniques and processes by which gold may be extracted from the earth. Placer mining is the technique by which gold that has accumulated in a placer deposit is extracted. Placer deposits are composed of relatively loose material that makes tunneling
In 2018, 7813.3 million tonnes Mt of coal were produced worldwide, primarily mined by two methods surface or 39opencast39 mining, and underground mining. The largest coal producing countries are not confined to one region the top five hard coal producers are China, India, USA, Indonesia and Australia. Much of global coal production is used
Conventional mining is the oldest method and accounts for only about 12 of underground coal output. In conventional mining, the coal seam is cut, drilled, blasted and then loaded into cars. Continuous mining is the most prevalent form of underground mining, accounting for 56 of total underground production. In continuous mining, a machine
Coal Mining Industry in Russia. In 2011, Russia produced about 336.3 million tons of coal materials. This illustrates 4 growth over the 2010 total production, so 2011 became a record level year in coal production in Russia. 90 of the coal output was provided by just the 18 largest producers in the coal mining industry, demonstrating the concentrated nature of the Russian coal mining business.

The most economical method of coal extraction from coal seams depends on the depth and quality of the seams, as well as the geology and environmental factors. Surface opencast mining and deep underground mining are the two basic methods of mining used in South Africa. Approximately 51 of South African coal mining is done underground and
The U.S. coal industry serves a vital role in the nations economy by producing fuel for more than half of its electricity. Despite the industrys importance, industry financial data for 2005the strongest year for the coal industry in recent yearsshows that it is a relatively small industry with revenues totaling 20 billion to 25 billion and net income between 1 billion and 2
in South Africa. The FRI went on to conduct worldclass research, and in 1957 a pilot coal preparation plant was constructed in Pretoria to enable largescale practical experimentation. The pilot plant played a pivotal role in the establishment of South Africas low ash coal export project. Political and economic factors contributed to the
