Abstract: The Joy Manufacturing Company was a major manufacturer of mining and materials handling machinery built upon the invention of the first practical coal loading machine by Joseph F. Joy (1883-1957). It is a somewhat random collection of documents assembled and preserved by the former corporate secretary James Packer (1920-2008) for the purpose of writing a never-completed company …

Andrew P. Schissler, in Encyclopedia of Energy, 2004 2.3 Strip Mining. Strip mining is employed in coal reserves where the overburden is removed in rectangular blocks in plan view called pits or strips. The pits are parallel and adjacent to each other. Strip mining is fundamentally different from contour or area mining on how the overburden is displaced, called spoil handling.

Surface techniques can be broadly classified into (1) contour strip mining, (2) area strip mining, (3) open-pit mining, and (4) auger mining. Contour strip mining. Contour mining is commonly practiced where a coal seam outcrops in rolling or hilly terrain.
Coal mining - Coal mining - Underground mining: In underground coal mining, the working environment is completely enclosed by the geologic medium, which consists of the coal seam and the overlying and underlying strata. Access to the coal seam is gained by suitable openings from the surface, and a network of roadways driven in the seam then facilitates the installation of service facilities ...

Strip mining had lasted 47 years and produced just under 50 million tons of coal. At the close of mining in the area, Peabody Coal Co., which had bought out the Northern some years earlier, sent the German-built wheel excavator, capable of moving 3200 yards per hour, to Belleville.
· If the coal reserves are located less than a hundred or so feet deep, then "Strip Mining" is the method of choice in the mining of the coal. A large machine, called a "Stripper" removes the rock and dirt, called the "Overburden", from the top of the coal seam. This exposed coal is then dug with smaller pieces of machinery called "Loaders".
The mining methods used in open cut coal strip mining in most major coal producing countries have been well established and fairly consistent over the past few decades. These general mining practices have been described by Kukla et al. (1993) and Aspinall et al. (1993) amongst others. Figure 1 shows a schematic of typical coal
· There were three of the giant machines at issue: The Tiger, The Mountaineer, and The GEM of Egypt.All three were then in the service of the Hanna Coal Company, which by 1970, had been strip mining in Ohio for decades and was then a division of the much larger Pittsburgh Consolidation Coal Company, later known as "Consol," itself then owned by Continental Oil.
Strip mining is a type of surface mining where the overlying vegetation, rock, and soil (overburden) is removed in order to reach the underlying coal seam, which usually lies a few feet beneath the surface. Explosives are used to fracture any overlying rock, and then heavy machinery is used to remove the overburden and dump it into a nearby area.

Mary McMahon Strip mining is done layers where the mining operations go slighter deeper with each pass. Strip mining is a type of surface mining which involves the removal of a thin layer of material known as an "overburden" to access buried deposits of useful minerals.This type of mining is only effective in areas where mineral deposits are very close to the surface, making it feasible to ...
"Strip mining" is the practice of mining a seam of mineral, by first removing a long strip of overlying soil and rock (the overburden); this activity is also referred to as "overburden removal" is most commonly used to mine coal and lignite (brown coal).Strip mining is only practical when the ore body to be excavated is relatively near the surface.
