Roof Support Jacks
|Mine Type: Underground Coal|
|Category: Roof and Rib|
It's a common task for miners to set jacks or dukes to support the roof. But there can be a hazard from a piece of rock falling when a miner releases the pressure and removes the jack.
A safety tip is to release and remove roof-support jacks remotely.
A pull rope can be rigged to trip the jack from a safe distance. Then the same rope can be used to drag the jack out of the area.
