Features include: integral jacking can with 675 ton capacity; screw conveyor 1 is an open ribbon type with integral full diameter gate; screw conveyor 2 is directly connected to the first conveyor; foam and bentonite slurry
additive system for conditioning of spoils; and an integral laser guidance system.
The opening was maintained with a bentonite slurry
mixture with a specific gravity of approximately 1.
