Coal Silos

Coal Silos - Wright, Wyo.

CLIENT
Thunder Basin Coal Company

Ibberson completed design and construction of two 70‑foot-diameter by 275-foot-high slipformed silos at the Thunder Basin Coal Company Mine in Wright, Wyoming. The project consisted of piles, foundations, slipforms walls, elevated slab and hopper, and roofs.

The silos are supported on 432 high-capacity “H” piles and a six-foot-thick monolithically cast concrete foundation. The roof is composed of traditional structure steel and decking with concrete.

The internal elevated slab is approximately 85 feet above the slab on grade. Each elevated slab consists of nearly 2,100 cubic yards of concrete and 225 tons of reinforcement. The structural steel hopper, which is cast into the elevated slab, weighs 310 tons.

Construction was unique as Wyoming weather is often unpredictable and can create a challenging environment. The structure was slipped in November and the roof was constructed in December and January. High winds and snow often restricted work and schedules were adjusted to maintain progress.

These massive coal silos have a combined capacity of 35,000 tons and are designed to operate 24 hours per day, 7 days per week with minimal downtime for maintenance.
