It is very essential that an adequate quantity of coal should be stored. The coal storage gives protection against the interruption of coal supplies when there is a delay in the transportation of coal.Read More
Discusses the development of coarse coal pipeline technology requiring a minimum of product size reduction. Initial concentration on continuous face haulage and later on mainline haulage areas led eventually to the system in operation at Loveridge mine in West Virginia. Key features of the hydraulic ...Read More
The coal is then loaded on to large trucks or conveyors for transport to either the coal preparation plant or direct to where it will be used. Mine rehabilitation. Coal mining is only a temporary use of land, so it is vital that rehabilitation of land takes place once mining operations have stopped. In best practice a detailed rehabilitation or ...Read More
