Stateowned mining giant Coal India (CIL) imports equipment including continuous miners equipment, crawler dozers, drills, dumpers, electric rope shovels, frontend loaders wheel dozers, hydraulic shovels and motor graders.. CIL incurs Rs35bn () on the imports and an additional Rs10bn is paid as customs duty. Hence, a plan has been proposed to phase out its imports in the next fiveto ...
Underground mining, sometimes called deep mining, is a process that retrieves coal from deep below the Earth's surface—sometimes as far as 300 meters (1,000 feet). Miners travel by elevator down a mine shaft to reach the depths of the mine, and operate heavy machinery that extracts the coal and moves it above ground.
The Indian government is seeking to reduce imports of heavy mining equipment worth over INR 35bn (465m) annually by encouraging domestic manufacturers to produce such machinery. Coal India alone imports highcapacity equipment with a customs duty of INR 10bn, the coal ministry said. India is trying to decrease its reliance on imported heavy equipment to boost domestic production and reduce ...
