2016. 5. 3. With growing demand for mineral resources and favourable policy towards the mining sector, developing countries have become investment hubs for mineral extraction, which has changed the socioeconomic and ecological scenarios particularly in rural areas. Extractive industries such as coal mining generate negative externalities that bring irreversible changes in the local ecological
In India, around 92% of the coal is produced by opencast mining method (Table 1). If do mestic coa l pro duction cont inues at 5% increasing rate, the extractable r eserve will last for 45 years.
Coal is one of the most essential resources of a country. It is widely used for power generation and as a raw material in the industries. India ranks third in coal production. However, the country has to import coal in order to meet the rising demand

2020. 11. 10. Coal prices are practically government-dictated in India. And the government is focussed on keeping fuel prices low for the power sector, which consumes at least 80 per cent of CIL’s production.
2021. 1. 10. Coal India subsidiary South Eastern Coalfields’ Kusmunda opencast coal mine in Chhattisgarh is the largest project to receive clearance. This mine is capable of producing 62.5Mtpa when operating at full capacity.
2021. 1. 21. List of equipment used in opencast coal mining are: 1. Bulldozer 2. Craper 3. Ripper 4. Tractor Shovel 5. Dipper Shovel 6. Stripper Shovel 7. Pull Shovel or Hoe 8. Dumpers or Tippers 9. Drag Line 10. Road Grader 11. Rock Drills. Opencast mining is the oldest method of excavating minerals but the mining operations have been mechanised by the use of heavy earth moving machinery during the
Coal is mined either by surface methods (open-cut or open-cast mining) or by underground techniques. In surface mining, all of the rock from the ground surface to the top of the seam (material referred to as overburden) is removed and set aside to expose the coal, which is then taken out and transported from the mine for preparation and use ( Figure 11 ).
