This mod adds 3 Tiers of Bucket wheel Excavators- Basically very big Mining drills.
With 80 item/s and up to 5 Module Slots, they do fit for any mining task. But be aware of their massive pollution.
They have similar energy usage as their originals:
Mk-I 5,56MW (Bagger 258)
Mk-II 9,50MW (Bagger 262)
Mk-III 16,56MW (Bagger 288)
