The East Broad Top Railroad & Coal Company, or EBT, is a legendary narrow-gauge short line located in south-central Pennsylvania. It historically was known as a profitable coal-hauler although that ventured ended in 1956. The road dates back to the mid-19th century and survived as a popular tourist line thanks to the efforts of Nick Kovalchick

Jan 30, 2021 · Longwall mining machines are about 800 feet (240 meters) in width and 5 to 10 feet (1.5 to 3 meters) tall. The miners extract "panels" -- rectangular blocks of coal as wide as the mining machinery and as long as 12,000 feet (3,650 meters). Massive shearers cut coal from a wall face, which falls onto a conveyor belt for removal. As the miner advances along a panel, the roof behind the …
Oct 06, 2016 · Large scale earth moving equipment is used to excavate and remove coal from lower layers. The equipment used depends on the method and scale of the surface mining method being employed. Regrading begins as coal excavation continues. Once coal removal is complete, final regrading takes place and the area is revegetated
The primary planning mechanism used in strip mining is the range diagram, which is a cross-sectional plan of the shape of the pit in various stages of mining. The range diagram allows the dragline or continuous excavator equipment characteristics of dig depth, reach, and physical size to be placed on the geologic dimensions of depth to seams (overburden), and depth between seams (interburden)
Surface coal mining generally involves the following sequence of unit operations: (1) clearing the land of trees and vegetation, (2) removing and storing the top layers of the unconsolidated soil (topsoil), (3) drilling the hard strata over the coal seam, (4) fragmenting or blasting the hard strata with explosives, (5) removing the blasted material, exposing the coal seam, and cleaning the top of the coal seam, (6) fragmenting the coal …

In surface mining, the ground covering the coal seam (the overburden) is first removed to expose the coal seam for extraction. The elements of a surface mining operation are (1) topsoil removal and storage for later use, (2) drilling and blasting the strata overlying the coal seam, (3) loading and transporting this fragmented overburden material (called spoil), (4) drilling and blasting the

The range diagram allows the mine planner to identify the equipment dump height required to keep the displaced overburden (spoil) from crowding the machinery and mining operations. In certain cases of mining multiple coal seams from one pit, a coal seam can provide the …
The U.S. coal industry serves a vital role in the nation’s economy by producing fuel for more than half of its electricity. Despite the industry’s importance, industry financial data for 2005—the strongest year for the coal industry in recent years—shows that it is a relatively small industry with revenues totaling $20 billion to $25 billion and net income between $1 billion and $2
