Coal is a critical enabler in the modern world. It provides 41% of the world's electricity and is an essential raw material in the production of 70% of the world's steel and 90% of the world's cement. 2 Fossil fuels today provide over 80% of the world's primary energy, a percentage not forecast to change significantly for decades to come. 3 With …
Surface mining is often used when coal is less than 200 feet underground. In surface mining, large machines remove the topsoil and layers of rock known as overburden to expose coal seams. A form of surface mining, mountaintop mining, is where the tops of mountains are removed, allowing for almost complete recovery of coal seams. …

In terms of coal mining in the U.S, the first set of regulating the laws environmental effects of coal mining was established by the Surface Mining Control and Reclamation Act of 1977 (SMCRA). SMCRA along with its regulations establishe s environmental standards that coal mine operators must follow while operating and …
Coal tailings are byproducts of the coal washing process and pose significant environmental pollution issues due to the release of heavy metal elements. In this study, a sustainable bioleaching method was proposed, and a Bacillus inaquosorum B.4 strain with high Extracellular Polymeric Substances(EPS) production characteristics was isolated ...
