The shearer is an important piece of equipment at the fully mechanized coal mining face ().The pick is the core component of the cutting unit as the key device of the shearer [1,2].During automatic and intelligent cutting at the coal mining face, the complex geological conditions, such as the fold structure, fault structure and magmatic intrusion, induce distinct occurrence conditions of coal ...

1875: Coal coke replaced charcoal as the chief fuel for ironblast furnaces. 1877: A steampowered shovel excavated some 10 feet of overburden (earth covering a coal deposit) from a 3footthick coal bed near Pittsburg, Kansas. 1880s: Coalcutting machines became available (before that, coal was mined underground by hand).
An analysis of coal fragmentation due to the action of a continuous miner is presented. Underground coal cutting by a drumtype continuous miner was simulated in the laboratory using a specially designed unique automated rotary coal cutting simulator (ARCCS). The rotary coal cutter provided the versatility of varying the operating and insitu ...

The Anderton Shearer Loader is a coal cutting machine which was used in the UK coal industry after 1953. The Anderton Power Loader with its cutting drum up to five feet in diameter was patented in 1953. It was successfully used throughout the British coalfields and by 1966 cut half the coal produced and by 1977 it produced 80% of the coal mined ...

Obviously, smaller carbides with sharp tips are used in soft rock applications such as gypsum, trona, coal, and salt. For the heavy duty tools used on CM and road header machines, cutting hard and abrasive formations such as sandstone, limestone and similar sedimentary rock, the diameter of the carbide is bigger. It sometimes is up to 40mm ( ...

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 ...

misc{etde_, title = {Longwall mining in South Africa} author = {Reid, B} abstractNote = {About twothirds of South African coal production comes from 12 large mines each with a capacity in excess of 6 million tons annually. Of these companies, Amcoal, Sasol, Trans Natal and Iscor operate underground mines that use longwall technology to produce about 12 million tons per year, or 8% of ...
Longwall shearers cut away the face of a coal seam in longwall mining operations by mounting over an armored face conveyor (AFC). They are equipped with cutting drums positioned against the coal seam by ranging arms powered by hydraulic rams. They can weigh more than 100 tons, travel at speeds up to 30 m/min, and cut away slices of coal seams up to 100 cm thick.

China is the world's largest coal producer and consumer. At present, coal is the main energy source in China and will still serve as its basic energy source in 2050 [1,2,3,4].In recent years, large coal mines in Shanxi, Shaanxi, and Inner Mongolia have been put into operation, and fully mechanized faces (FMMFs) with large mining heights contribute to fulfilling the overall target of annual ...
evaluation of coal cutting equipment. The tool life of bits is limited by their wear rate. It occurs because of relative frictional motion between rock/coal and tool. Wear of the cutting tools is one of the most important process parameters for evaluating the economy of process and efficiency of the operation (Maidl et al. 2008).In general ...
The National Coal Board (NCB) Film Unit is one of Britain's most substantial and longlasting industrial film units.

The slot made by the cutting machine is known as the 'cut' or 'kerf'. Normally the cut is 5" or 6" high and penetrates the seam to a depth of 4' 6" or 6', although cuts are sometimes made as shallow as 2' and as deep as 7'. If the cut is made at floor level, the seam is said to be 'undercut'.
The first coal cutting machine used in Australia was a Gartsherrie Coal Cutter. Although relatively unsuccessful at the time, the chain cutter principle was revived by Anderson Boyes in 1906 and it became one of the most commonly used types of coal cutter, exported worldwide. ...

Continuous miners are used primarily in roomandpillar mines and operate similarly to longwall machines. They account for nearly 45 percent of all underground coal mined. In 1935, two percent of West Virginia's coal was loaded by machines; 20 years later, 99 percent was machine loaded.

The interest in understanding the wear mechanisms of cemented carbide (CC) is not a new development. For a long time, there have been studies on different wear mechanisms under different coal/rock cutting conditions. These studies have helped improving the quality of CC, thereby preventing such wearing of tools. Due to highly unpredictable character of coal/rock, the wearing phenomena cannot ...
The performance of a coal cutting machine is not dependent solely upon its mechanical characteristics but also upon the nature of the seam in which it is working, and whilst the former aspect has been extensively studied, /85/ 1985 Elsevier Science Publishers 254 the latter has been neglected. For maximum efficiency a coal ...
