The National Coal Board (NCB) Film Unit is one of Britain's most substantial and longlasting industrial film units. The following is an informative film of how a longwall coal cutter works and how it strips coal from the face. Title Operating A Longwall Coal Cutter Nine out of ten machines used in cutting coal are longwall coal cutters.
Several of the machines, including this one, where used at the Atlas #3 and #4 and greatly improved productivity. The Historic Atlas Coal Mine preserves and interprets Drumheller Valley's rich mining history. Located on Highway 10 in East Coulee, the Atlas Coal Mine is an Alberta Historic Resource. 64.
Instructions for the Working of William Baird and Co's CoalCutting Machines, about 1870. The first chain coal cutting machine was invented in Coatbridge in 1871 by John Alexander of the iron and coalmasters William Baird and Company. This kind of coal cutter works much like a chainsaw, with sharp metal teeth attached to a moving chain.

Conical pick is a widely used tool for cutting coal in mines. It has a cemented carbide tip inserted in a steel body. Cemented carbide has been in use for many years for coal/rock cutting because it has the optimum combination of hardness, toughness and resistance against abrasive wear. As coal/rock is a heterogeneous substance, the cutting tool has to undergo various obstructions at the time ...
Coal mines operated without electricity. Electricity began to be adopted in mining and manufacturing in the late 1880s and the 1890s. (Electricity was first introduced into Ohio's bituminous coal mines in 1889.) The introduction of electricity in coal mines greatly facilitated the introduction of laborsaving machinery. 1891.
Longwall mining is a form of underground coal mining where a long wall of coal is mined in a single slice (typically m (2 ft 0 in 19 ft 8 in) thick). The section of rock that is being mined, known as the longwall panel, is typically 34 km ( mi) long, but can be up to km ( mi) long and 250400 m (8201,310 ft ...

The use of coal cutting machines, first introduced in the 1870s, accelerated in the early decades of the twentieth century. In 1915, percent of the total national coal was mechanically cut; the percentages were higher in the four main producing states (in 1900): Illinois, Ohio, Pennsylvania, and West ia (Dix 1977, p. 20).
Mechanical cutting. Our comprehensive range of mechanical cutting equipment offers effective solutions for a wide range of underground mining and construction applications, including rapidentry roadway development, demanding production settings without drilling and blasting, as well as boring of ore passes and ventilation shafts.
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 (). Like many industrial companies, it underwent a period of conglomerate diversification and contraction in the 1960s and 1970s, before itself becoming ...
The company also introduced especially designed personnel and materials carriers to move men and materials inside the mine, and the company manufactured the first electrical coal cutting machine. Goodman Equipment ultimately developed an entire product line of locomotives—both electrical and diesel—for underground mining and tunneling.
The first electric coal cutting machine is also introduced.:: 1913 Peak UK coal production, with more than 287 million tonnes of coal mined and the industry employing million people.
A coal cutting machine is used in underground mines. Therefore, it is generally used in board and pillar and longwall mining methods. The coal Cutting machine is also known as CCM. Hence, It is used to remove coal by providing cuts on the face. CCM is also provided with a free face for the blasting. It is generally moving with the help of skid ...
A simple machine, the Joy loader featured two arms attached to the front of a short conveyor belt. The arms moved in a wide sweep, gathering loose coal and scooping it onto the conveyor belt, which then deposited the load into a shuttle car. Inventor Joseph Francis Joy (September 13, 1883February 1957) was born in Cumberland, Maryland.
