Coal is a black or brownishblack sedimentary rock that can be burned for fuel and used to generate electricityIt is composed mostly of carbon andWhy mining? Mining without any doubt is a key component of our lives Before jumping into the various types of mining, let’s cover why mining?

Coal fired power plant Energy Education
Coal fired power plants also known as coal fired power stations are facilities that burn coal to make steam in order to generate electricityThese stations, seen in Figure 1, provide ~40% of the world's electricity Countries such as South Africa use coal for 94% of their electricity and China and India use coal for 7075% of their electricity needs, however the amount of coalElectricity from coal is called thermal power The coal was formed millions of years ago when giant ferns and swamps got buried under the layers of earth Coal is therefore referred to as Buried Sunshine The leading coal producers of the world are China, USA, Germany, Russia, South Africa and FranceCBSE Notes Class 8 Geography Chapter 3Mineral and
What are the different types of power plants used to
Nuclear, coal and wind are just three types of energy that are used to generate electricity in power plants across the world But as a number of countries continue to move away from highpolluting fossil fuels towards lowcarbon alternatives , the dynamic of how and where power plants operate is constantly changingSafety in coal mining is a very urgent issue as it is estimated that around 500 coal miners die every year in mine accidents in China only (World Bank, 2007) Environmental impacts of coal burning include increased amounts of carbon dioxide in the atmosphere, that together with other greenhouse gases, such as nitrogen protoxide (N 2 O) andMining industry and sustainable development: time for
