Longwall mining equipment is the heart of modern underground coal extraction. Used in high-production faces around the world, these systems combine powered roof supports, shearers, face conveyors and digital automation to maximise productivity and safety in underground coal seams.
When every advance of the face has to be safe, fast and profitable, you need a fully-synchronised system—powered roof supports, armoured face conveyors, beam stage loaders, crushers and digital controls—that works as one. That’s exactly what Becker-Warkop delivers.
What Is Longwall Equipment?
Longwall equipment is an integrated set of machines that shears coal in a continuous “slice”, supports the roof while the seam is mined, and transfers the coal out of the panel. A complete system includes:
- Powered Roof Supports (PRS) – hydraulic shields that hold up the roof
- Armoured Face Conveyors (AFC) – chain conveyors that carry coal along the face
- Beam Stage Loaders (BSL) – transfer points that feed belts and house in-line crushers
- Crushers & Pushers – size reduction and advancing devices
- Control & Electrical Systems – automation, power distribution and data capture
Together, these components allow longwall faces to produce millions of tonnes of coal with minimal human exposure at the cutting edge.
These hydraulic roof supports are engineered for continuous operation in methane-prone zones and can be equipped with modern electrohydraulic systems, load sensors, and automatic pressure regulation.
Benefits of an Integrated Longwall Mining System
A fully synchronised longwall system offers multiple operational advantages over room-and-pillar methods:
- Higher productivity per shift
- Lower cost per ton of coal extracted
- Reduced miner exposure near cutting edge
- Automated cycle time and improved roof control

Frequently Asked Questions
What is longwall equipment used for?
Longwall equipment is used to mine coal in long horizontal slices using automated cutting and conveying systems.
How much coal can a longwall face produce per day?
Modern longwall systems can extract 5,000 to 15,000 tonnes of coal per day, depending on seam conditions and equipment configuration.
Can Becker-Warkop longwall systems be retrofitted?
Yes. We offer retrofit programmes for legacy roof supports, control units, and shearer interfaces to meet current safety and automation standards.
