Safety Precautions on Coal Stockpiles
Due to the relatively small stockpiles, dozers are continuously required to store and reclaim both raw and clean coal.
Stockpile Maintenance Procedures
Where people are required to operate equipment or travel on foot on a stockpile equipped with a reclaim belt and draw-off feeders, West Virginia Code 36-27-5.1 requires an approved plan.
The Approved Plan Has Proven to be a Good Practice
The Plan Consists of Three Basic Elements
Equipment Requirements
Entrapment Rescue Procedures
General Rules and Safe Procedures Required for Working on Stockpiles

Safety Precautions on Coal Stockpiles Required rules and safe job procedures.
Stockpile Maintenance Procedures
Warning signs will be posted at all entrances to live stockpile areas.
No person shall travel on foot over feeders without a secured overhead life line and feeders locked and tagged out.
In the event of an emergency on any stockpile, all feeders shall be turned off by the plant operator until the entire situation has been accessed by the on-shift supervisor in charge.
If equipment communications or remote stop device fail, then the effected piece of equipment will be removed from stockpile operation until repaired .
When a cavity is suspected, the equipment operator will fill the cavity by side cutting along the bottom of the stockpile area until the cavity is filled.
Water sprayed from inside the reclaim tunnel up through a feeder may also be used to attempt to collapse the cavity until the cavity is filled.
A copy of the approved plan shall be posted at the mine and persons performing such work shall be properly instructed on the plan contents prior to any work being performed.
