Bucket-wheel excavator - Wikipedia

The primary function of BWEs is to act as a continuous digging machine in large-scale open-pit mining operations, removing thousands of tons of overburden a day. What sets BWEs apart from other large-scale mining equipment, such as bucket chain excavators, is their use of a large wheel consisting of a continuous pattern of buckets used to scoop material as the wheel turns.

The mine is infamous as in March 1988 mining was brought abruptly to a halt by a catastrophic failure of a 70 m deep excavation wall, which then allowed the River Aire to flow into the site from both upstream and downstream sections of the river. There was still much coal to be mined ...
