Conveyor Belt Skirt Boards
| An average of forty miners are injured each year by material falling from belt conveyors. Although these injuries are generally not serious, almost half result in lost work time. Over a five-year period, the average number of lost-work days per injury was 12 at metal and nonmetal mines and 23 at coal mines.
The use of skirt boards can limit the amount of material that falls from conveyors and exposes miners to injuries. The cost can be optimized by placing the skirt boards at "high-risk" areas along the belt line, where these type of accidents are more likely to occur.
To reduce such accidents, mine operators should do the following:
1) Install skirt boards on conveyors at locations that have a higher likelihood of material falling off the belt, or a higher chance for miners to be exposed to this hazard, such as:
