The biggest coal mining machines are massive pieces of equipment designed to handle large-scale extraction efficiently. Here are some of the largest and most powerful coal mining machines in the world:
1. Bagger 293 (Bucket-Wheel Excavator)
– Manufacturer: TAKRAF (Germany)
– Weight: 14,200 tons
– Height: 96 meters (315 ft)
– Length: 225 meters (738 ft)
– Bucket Capacity: 20 cubic meters (700 cu ft) per scoop
– Daily Output: Up to 240,000 tons of coal
– Use: Primarily in lignite (brown coal) mining in Germany.
2. Bagger 288 (Bucket-Wheel Excavator)
– Manufacturer: Krupp (Germany)
– Weight: 13,500 tons
– Height: 95 meters (311 ft)
– Length: 220 meters (721 ft)
– Bucket Capacity: Up to 6.6 cubic meters per bucket
– Daily Output: Over 240,000 tons of overburden/coal.
– Notable Fact: One of the largest land vehicles ever built.
3. Dragline Excavators (e.g., Bucyrus RH400 / Cat 8750)
– Manufacturer: Bucyrus/Caterpillar
– Weight: ~7,000–8,000 tons
– Bucket Capacity: Up to 135 cubic meters (4,800 cu ft)
– Boom Length: ~100 meters (~330 ft)
– Use: Stripping overburden in open-pit coal mines.
4. Large Mining Trucks (e.g., BelAZ 75710)
– Manufacturer: BelAZ (Belarus)
– Payload Capacity: 450 tons (~496 US tons)
– Engine: Dual diesel engines (~4,600 hptal)
– Used for hauling coal and overburden in massive mines.
5. Continuous Miners & Longwall Systems
While not as visually colossal as bucket-wheel excavators, modern longwall shearers and continuous miners are highly efficient:
– Shearer Loaders (e.g., Eickhoff SL1000) can cut up to *5,
