Longwall Mining — One of three major underground coal mining methods currently in use. Employs a steal plow, or rotation drum, which is pulled mechanically back and forth across a face of coal that is usually several hundred feet long. The loosened coal falls onto a conveyor for removal from the mine.
underground coal mines to protect conveyor belt installations have been in place since the Coal Mine Health and Safety Act of 1969 was enacted. Over time, the coal conveyer equipment being used and ventilation conditions underground have changed significantly, particularly the width of the conveyor belts and the use of belt air at the face.
Conveyors have long been referred to as the arteries of a mining operation – critical to the movement of material through the system. If the conveyors stop, the mine stops; it's as simple as that. We are the leaders in designing and building mine conveyor systems that .

Underground Coal Mining. Underground mining involves opening one or more portals or shafts into the earth that follow or intercept coal seams that are too deep for surface mining methods. Two main methods of underground mining are practiced in Pennsylvania:
• 33% of all Coal Production in the U.S. is from Underground Mines • 63% of all Coal Produced East of the Mississippi is from Underground Mines – In all states east of the Mississippi, except Indiana and Tennessee, the majority of coal production comes from underground mining activities • 9% of all Coal Produced West of the Mississippi is
The project included a coal truck dump hopper, feeder, and incline conveyor feeding 160 TPH of coal to a new storage silo. SMG reviewed layout drawings, and completely engineered and designed the enclosed gallery-style conveyors, the feeders, the truck dump hopper and discharge feeder, the enclosed towers, and all of the conveyor supports/bents.

layout. 1. Introduction Transport developments followed two distinct routes in each of the major functions, namely the movement of ore/coal, persons, materials and equipment. Ore/coal transport has either been by locomotive-hauled mine cars, belt conveyors or rubber-tired trucks.
The Problem with Designing a Conveyor System. The designer of belt conveyors is often faced with problems of determining the proper belt speeds, belt widths, number of plies in the belt, and idler spacing for conveyors employed in various parts of a mill.
Metropolitan uses underground longwall mining techniques to extract the coal which is then transferred by conveyor to the major surface facilities area. The coal is transported by train to the Port Kembla Coal Terminal for shipping to domestic and overseas customers.
The target stopping time was 35 seconds. The conveyor layout was non-traditional since it is a panel conveyor and the tail is being moved regularly. "Typically, the brake would be installed on the tail pulley, but in this case, the mine's preferred brake position was toward the head end of the conveyor," according to Coward.
Optimisation of cutting cycles in conventional underground coal sections to improve productivity serves as an area of study that deals with the utilisation of the machines in conventional underground coal sections. Utilisation of machines focuses on reducing the time that machines spend idle and increasing the amount of time during shifts that machines are actively contributing to production.

Coal provides America's railroads with more traffic and revenue than any other commodity. A typical train car holds between 115 and 117 tons of coal. Wyoming is the largest coal-producing state. Coal accounts for half of the electricity use in the U.S. Coal costs less than any other major fossil fuel source.
