"Performance study of mechanical loading machines

"In the transition from hand-loading methods in coal mining to mechanical loading methods various types of equipment have been developed to do the same job. Among the coal mining operators and among miners in the coal fields, various equipment preferences have developed.

e-WV Joy Loading Machine

Inventor Joseph Francis Joy (September 13, 1883-February 1957) was born in Cumberland, Maryland. He was introduced to coal mining at a young age, and himself had loaded coal in the old way. In 1919, he won a patent for his design of a mechanical loader, which became the Joy loading machine and in its various models dominated the market for coal

e-WV Joy Loading Machine

Joy Loading Machine. By replacing the labor-intensive job of hand-loading coal, the Joy loading machine helped revolutionize mining in the 20th century. When it was introduced in the 1920s, the Joy loader was one of several coal-loading machines on the market.

Machines Used in Coal Mining Career Trend

2018-11-28  For extracting coal which lies close the surface, huge drag-line shovel machines remove the topmost layers of soil and rock, exposing the coal, which is then removed by smaller machines. Surface mining may involve removing sections of hills or top layers of a flat surface area. The layers of rock and dirt covering the coal are reserved for until the coal is removed, at which point the the dirt and rock is replaced, the mine

Reliability modelling and performance analyses of an LHD

2009-8-26  pillar method of coal mining introduced sophisticated automated side discharge loader (SDL) / load haul dumper (LHD) machines for loading of coal in place of manual loading. Among the face loading machines, the electric LHD is now the dominant machine in intermediate technology and plays an important role in district or overall mine production.

Coal Mining an overview ScienceDirect Topics

1990-4-1  The introduction of the mechanical coal-loading machine, for instance, reduced the need for coal miners by approximately 30% industrywide between 1930 and 1950. According to Ronald Lewis, black miners bore the brunt of layoffs during this period because they were disproportionately employed as hand loaders.

From Shovels to Machines National Coal Heritage Area

2021-7-7  Machines were introduced gradually during the early 1900s, allowing miners to load more coal in less time. Mechanization began with undercutting machines around 1900 and advanced to loading machines in the 1920s. At first, machines helped miners load more coal; eventually, they put the majority of miners out of work.

Coal-mining technology in China ScienceDirect

The coal seams in most of the existing coal-mining areas are to deep for surface mining. Therefore, about 96% of China's total coal production is from underground mines. Since the early 1950s great efforts have been made to improve coal-mining technology in China.
