Cutting Machines - Shearers | Introduction | …
A shearer consists of a machine body containing electric motors, hydraulic equipment and controls which is mounted over the AFC. Horizontal cutting drums are mounted on the face side of the machine, laced with cutting picks and rotating in a plane parallel to the face. If the AFC is pushed towards the face as the cutting drums are rotated and the shearer travels along the face, it is able to cut into the face …

Shearer operation technology allows the programming of fully automated cutting sequences, including gate end turnarounds. Users can create an initial cutting profile and extraction heights using a graphical planner; the machine then uses the plan to automatically replicate the profile until conditions change. The operator can then override control of the roof drum to follow the preferred horizon. Using the new …
Introduction to Longwall Mining and Subsidence ver2
The shearer cuts a slice of coal from the coalface on each pass and a face conveyor, running along the full length of the coalface, carries this away to discharge onto a belt conveyor, which carries the coal out of the mine.
Longwall mining - Wikipedia
The shearer is carried along the length of the face on the armoured face conveyor (AFC); using a chain-less haulage system, which resembles a ruggedised rack and pinion system specially developed for mining. Prior to the chainless haulage systems, haulage systems with chain were popular, where a heavy duty chain was run along the length of the coal face for the shearer to pull itself along. …
