Longwall Shearers FAQ
Key answers for underground coal mine owners,
engineers and procurement teams
1. What are Longwall Shearers?
Longwall Shearers are underground mining machines
designed to cut coal continuously along a longwall face.
2. Where are they used?
Longwall Shearers are used in underground longwall
coal mining operations.
3. What seam heights are suitable?
Longwall Shearers can be configured for low, medium
and high coal seam applications.
4. What cutting power is available?
Longwall Shearers are available with different cutting
motor powers and drum configurations.
5. What drum sizes are available?
Longwall Shearers can use different drum diameters and
cutting widths based on seam conditions.
6. How do they move along the face?
Longwall Shearers use electric or hydraulic haulage
systems to travel along the AFC.
7. Can they be automated?
Yes. Longwall Shearers can support remote control,
automated cutting and longwall system integration.
