Making Complex Cutsequences Easier

Feb 27, 2018 Determining the most productive cut-sequence at a mine requires complex calculations and consideration of multiple factors, including the haul trucks most efficient route to the waste dump. For large open-pit mines that have waste dumps with multiple access roads, planning is even more difficult.

Cutting Methods Longwall Underground Coal

The basic cutting methods are Bi-di and Uni-di. Half Web methods have been introduced to provide several benefits, mainly in productivity, but at a cost of being more complex not a cost once crews are fully trained. Some Half Web systems can provide similar benefits to Pre-cutting, also described in the Longwall section of the Fundamentals of Coal Mining module, but with additional benefits.
