Amax Coal Company
Belle Ayr Mine Facilities
Gillette, Wyoming
Under a turnkey contract, Roberts & Schaefer provided complete
project management, detailed engineering, procurement, and construction
services, to build the coal handling, crushing, storage, and loadout
facilities for Amax Coal's Belle Ayr mine. The facilities are
designed for a production rate of 12 million tons per year. The
Belle Ayr mine was the first major high capacity coal facility
built in Wyoming's Powder River Basin.
Run-of-mine coal is delivered at a rate of 2,000 TPH to a truck
dump primary crushing station, crushed, then conveyed to secondary
crushing where it is crushed to its final 2 inch X 0 size, sampled,
and moved to two 12,000-ton storage silos. Each silo is configured
to flood load unit trains at a nominal rate of 9,000 TPH. The
silos are arranged in line over the track-loading loop.
