Roof Supports Customized Design Caterpillar is the world leader in longwall roof support technology. In the early 1970s, demanding mining conditions in German coal mines set the stage for extensive R&D in roof support technology. Steeply inclined coal seams both thick and thin, weak roofs and massive sandstone roofs, soft floors, and geological faults called for a high degree of customization. The resulting expertise has been deployed and applied to all mining areas of the world and provides customers with state-of-the-art technology customized to maximize control of the roof and floor of...

Taking the Shearer to the Next Level Your shearer is the most critical part of your longwall production process. That’s why high-performance longwall operations demand shearers that deliver the highest productivity, availability and reliability. Cat shearers were always designed to meet these demands. But Caterpillar has taken them to the next level. To do this, we invested heavily in refining our successful range of shearers. We started by reviewing and analyzing all more recent shearer installations and setting goals to improve productivity, availability and reliability. This was not a...

Automated Plow Systems High-level Automation We have been designing and building longwall plows since 1941 – and things have come a long way. Technical developments since 1990 have once again established plowing as the preferred longwall mining method for seams below 1.8 m (71 in). Cat plows offer world-leading features that other manufacturers cannot and a cost of ownership that far outstrips the shearer when mining thin and medium seams. Their reliability, high-productivity and ability to mine in-seam make them the ideal choice for longwall mining medium and thin seams. Cut any Coal There...

Moving Mountains No matter how fast your shearer can cut, you can’t keep cutting until you move the coal away from the face. Cat Armored Face Conveyors (AFCs) are designed to keep things moving and to carry the maximum possible amount of coal smoothly away from the coalface. They are designed for high availability and economy in operation. They are easy to maintain and offer long service life and a great return on investment to mine operators. Cat AFCs excel through cutting-edge technology, quality, experience and superior product support. Of course, that’s what any AFC manufacturer would...

Roadway Development Before longwall mining begins, gate roads are driven to the back of each panel by continuous miners. The Cat CM200 Series of continuous miners are the machines of choice to perform a room and pillar operation to develop longwall panels. The gate roads provide passages for longwall equipment, workers and conveyor belts used to transport coal to the surface. Roof support is one of the main bottlenecks in entry roadway development. Caterpillar offers a miner bolter model to solve this problem. With one-pass mining at cutting heights from 2.4 m (7.8 ft) to 4.1 m (13.6 ft)...
