2016 Award Winners:

Fan Hanging Machine (Metal Sector)

Hanging auxiliary fans in underground metal mines is a difficult and potentially hazardous job, as the fans are large and the equipment currently used to lift them into place does not provide a safe location for workers away from the suspended load. Small Mine Development, LLC, and JH Fletcher together developed a purpose-built fan hanging machine to protect mine workers from the potential hazards of working around a large, suspended load. This machine securely holds the fan and has a platform for miners that travels up with the fan and moves independently along the length of the fan.

Stockpile Safety System (Coal Sector)

The safety of workers who operate dozers on surface stockpiles at mines depends on knowing where feeder locations are, and if material is feeding properly from above operating feeders. Arch Coal, Inc.’s Leer Mine developed a stockpile safety system to enhance dozer operator awareness and to help eliminate stockpile dozer incidents. The system offers video to the dozer operator and the plant operator of the dozer's location on the stockpile in relation to the feeders. An audible warning is provided if the dozer enters a zone above the feeder. In addition, the operators can confirm via video that the coal is being pulled from the surface of the stockpile to indicate there are not any voids. This system represents a significant advance to enhance dozer operator awareness to help eliminate future stockpile dozer incidents.

Dry Scrubbing System (Industrial Minerals Sector)

Airborne dust generated when ore is handled or transported can be a health hazard for mine workers. Focusing on the conveyor transfer point as a significant airborne dust contributor, Tronox Alkali developed a dry scrubber system that separates the dust particles from the air and uses an automated compressed air pulse system to clean the filters. The removed dust is collected in a hopper where it is mixed with water and then pumped to a mining sump. The system has been very effective and the company plans to have a second system operational soon.
