Impacts of exploitation of fossil fuels The harvesting and utilization of fossil fuels creates many environmental problems. Coal is a fossil fuel that creates many negative impacts on the environment during every stage of its processing. First, coal mining is accomplished by a number of ways.
This study seeks to provide fresh insights by focusing on residual coal exploitation and its impact on both the sustainable development of the coal industry and a sustainable supply of coal in China. The Hubbert model and survey were used to address the prediction of coal R/P ratio and the trend of residual coal exploitation.
Coal mining in India has a long history of commercial exploitation starting in 1774 with John Sumner and Suetonius Grant Heatly of the East India Company in the Raniganj Coalfield along the Western bank of Damodar River. Demand for coal remained low until the introduction of steam locomotives in 1853.
