Technology News 518 - Super Stopping: A Permanent Solid Stopping for Directing Ventilation Airflows in Large-opening Metal/Nonmetal Mines

Highlights the Super Stopping. It is designed for use as a permanent, long-term ventilation control in large-opening metal/nonmetal mines. The stopping is composed of low-density, composite cement and fly ash blocks 48 inches long by 48 inches high by 32 inches wide and weighing approximately 1,200 lb. The Super Stopping is a massive, high-strength structure designed to last for the life of the mine. It is constructed by using an extended-reach forklift to lift and set each block. Factory-installed holes are cast into the blocks to readily receive the forklift tines.
