Coal Education
Coal is a black or brownish-black sedimentary rock that can be burned for fuel and used to generate electricity.It is composed mostly of carbon and hydrocarbons, which contain energy that can be released Problems of subsidence, water pollution, and potential fires are associated with augering. Highwall mining is an adaptation of auger mining. Instead of an auger hole, an entry into the coal seam is made by a continuous miner, remotely operated from a cabin at the surface. The cut coal is transported by conveyors behind the miner to the outside.Coal mining Underground, Surface, & Drilling Britannica

Coal mining trends, approaches, and safety hazards: a brief
Coal is one of the most vital sources of energy in world (Lechner et al. 2016).Energy is one of the indispensable aspects that play significant role in running the machinery of a country (Sontamino and Drebenstedt 2011).To gratify emergent energy demands, coal is spread across the globe in abundant quantities (Höök et al. 2010; Mohr At present, China’s intelligent coal mine construction is still in the primary development stage. The integrated development of a new generation of information and communication technology and the coal industry is accelerating, and this industry’s intelligent green transformation and upgrading is being promoted.

Coal Challenges and opportunities PwC India
Coal has been in the news over the past few months. Not without reason. The recent power crisis in India has moved coal to the centre stage. India’s energy sector depends heavily on coal as fuel for its thermal power plants. The ability of coal-based power plants to operate round-the-clock and provide base load capacity is central to meeting the growing India is the third largest coal producing country in the world. Coal contributing over 70% in electricity generation. Reforms started since 1991, created an unprecedented increase in demand of coal and the coal industry was able to achieve a production of 534.5 million tons against projected demand of 694 million tons during Coal Mining Challenges and strategies for bridging demand gap

The impacts of coal dust on miners’ health: A review
One of the important issue involved in coal mining is coal dust, which can lead to a series of health problems (Yao et al., 2020).Nearly the whole mining processes is accompanied by coal dust generation (Shahan and Reed, 2019).Fig. 2 depicts the processes of coal dust generation during mining, showing that dust is generated during The aging infrastructure of coal fired power plants is another factor resulting in closures. Between 2002 and 2018, 275 of the 530 U.S. coal plants were shut down or converted to natural gas (Richardson et al., 2017; Trabish, 2018), with plans to retire additional plants by 2030 (Richardson et al., 2017).Most coal plants in the United States The future environmental and health impacts of coal
