Mining picks body made from cold extrusion of high quality 42CrMo steel, the density is high, and there is no decarburization. It is mainly used for coal mining and drilling of roadway, tunnel and ground ditching. Used together with shearer, road header, pavement planer, etc.
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 in Britain.

DRAG TOOLS EMPLOYED ON SHEARER DRUMS AND ROADHEADERS Robert (*) Osman İMOĞLU (**) Sabri ALTINOLUK (***) ABSTRACT This paper outlines some practical and theoretical aspects of drag tools being employed in the mining and civil engineering industries. Discussed in the paper are the selection and reservicing of cutter
Other articles where Shearer is discussed: coal mining: Origins of longwall mining: .simple continuous machine called the shearer was introduced. Pulled along the face astride the conveyor, the shearer bore a series of disks fitted with picks on their perimeters and mounted on a shaft perpendicular to the face. The revolving disks cut a slice from the coal face as the machine.
The parameters for selecting a coal shearer for a longwall mining operation is contingent on the type of shearer, dimensions of the shearer as well as the haulage speed and power output of the machine. History. The mechanization of coal mining with cutting technology occurred as early as 1860.

These "picks" act in a fashion similar to chisels and break a narrow web of coal off the face (of the order of 300400mm thick). In most cases there are no moving parts on a coal plough. The plough itself is mounted on the front of the AFC and is pushed into the face by push cylinders mounted in the supports.

Pit Terminology Glossary. Glossary of words that are generally specific to the mining industry: Some have a two or three fold meaning, some have gone out of use, some are local to Derbyshire, Leicestershire, South Yorkshire and to Nottinghamshire, and others are general to the British Coalfields.
Mining pick is one of the vulnerable parts in coal mining and roadway driving machinery, and it is the main tool for coal falling and coal breaking. Its performance directly affects the production capacity of coal mining machinery, power consumption, working stability and the service life of other related parts.
