Underground mining of coal deposits using mass production technology can eliminate several issues Indian coal mining faces today such as the destruction of In India, coal mining is conducted using two methods: underground and opencast methods. The underground method is suitable for extraction of deeper coal seams, whereas opencast method is (PDF) Underground and Opencast Coal Mining

Mining is an essential industry that will provide key materials needed for India infrastructure development. Mining is one of the core sectors and growth driver of Indian economy. Minerals and ores provide basic raw materials to many important industries like power generation (thermal), iron and steel, cement, petroleum and natural gas, The largest coal mine in India in terms of reserves and production is the Jharia Coalfield located in the state of Jharkhand. Jharia Coalfield is estimated to have a reserve of around 19.4 billion tonnes of coal and accounts for over 60% of India’s total coal production. The coal in this field is primarily bituminous in nature and is used forCoal Mines in India List, Major Coal Fields, Types of Coal

The outlook for India’s thermal coal imports is finely balanced. With around 80 per cent of India’s thermal coal requirements satisfied domestically, the future for India’s thermal coal imports depends on small movements in the balance of India’s future coal production and consumption. In the short-term, imports are likely to remainHigh gassy mines have low recovery rates of coal resources in the stoping of high-seam coal resources in addition to difficulties in the gas control of the working face and gas accumulation in the goaf and upper corner. Pillar-free gob-side entry-retaining technology was combined with the high-pumping roadway for gas control in the goaf The Roadway Layout and Control Technology of Pillar-Free Mining

Coal is the most important and abundant fossil fuel in India. Coal-fired power plants meet 72% of India‟s electricity demand. Presently India is the second largest producer of coal in the world after China. India had a total coal resource of 344.02 Bt the total lignite reserve stands on 46.02 billion tons. Commercial primary energyLand for coal mining in central India, for example, is commonly secured through a series of ‘micro’ land grabs which although do not appear to be significant individually and hardly register as land grabbing but do, in sum, allow for the large-scale territorial transformations that the coal complex requires (Oskarsson et al., 2019).

Coal mining in India. India is rich in ancient coal fields like Gondwana coalfields (250 million years old) and tertiary coalfields (15-60 million years old). Coal mining was started during the rule of the East India Company in 1774 in the Raniganj coalfield along the western bank of the Damodar river. To increase coal production, the focus ofOld mine workings, mainly hidden galleries, goafs, shafts etc may pose a great threat to the local environment and also for future mine development. The present study mainly deals with delineation and mapping of old mine workings over Tikmani-Gareriya section, a part of east Basuria colliery, Jharia coal field, India using state-of-the-art 64 Detection of Old Mine Workings over a Part of Jharia Coal Field, India
