Mining. In Australia, nearly 80% of coal is produced from open-cut mines, in contrast to the rest of the world where open-cut mining only accounts for 40% of coal production. Open-cut mining is possible because coal seams are close to the surface. Such mining is cheaper than underground mining and enables up to 90% recovery of the Seepage of water through an underground coal-mine barrier is a common indicator of a potential hydrogeological hazard. The Jharia coalfield has witnessed several deadly inundation events in different underground mines. The present study deals with the mapping of water seepage through an underground coal-mine barrier of the Jogidih Water Seepage Mapping in an Underground Coal-Mine

Coal mining Prospecting, Exploration, Mining: The fundamental objective of coal prospecting is to discover coal resources through a search. In areas where coal mining has not been previously practiced, the search process should result in obtaining coal samples that give reasonable evidence of the existence of a coal seam. Once a seam has been China opened many new coal mines in the 2000s, which have a lifetime of about 30 years. The decisions countries like China and India make in the coming years around whether they continue to mineThe next 20 are years crucial in determining the future of coal
