Our strong reliable conveyor system will borne coal from underground working face up to surface with an average rate of more than eight thousand tonne per day. Development We are developing and maintaining longwall faces with 200 meters, which is also very rare and challenging of its kind in Indian mining history for higher and faster production.
The underground construction operation is connected to an underground work area classified as gassy and subject to a continuous course of air that contains the flammable gas concentration. The underground construction standard requires that gassy operations meet several special requirements, including both personnel and equipment safety concerns.
This method can be used in the sediment contained in the surface and also in an underground mine. For shallow sediments, this method is used in a test well. Groove (channel) is made on the side of the test wells. At a hydrothermal sediment mined by underground mining systems, channels made from hanging wall to foot wall.
