Pattern bolting is therefore required to prevent local loose rock from falling, but the bolts may be relatively short and light. Skin control is also an important secondary function of roof bolts with the other three support mechanisms. $ Suspension: In many mines, a thin layer of weak, immediate roof can be suspended from an overlying thick,

Loss of Control of Roof Along Face underground COAL

The loss of roof control can vary from broken roof over the supports, through minor loss of roof material ahead of the supports, up to major cavities ahead of the supports. More often than not, this is a progressive deterioration and the sooner action is taken to correct the issue, the better.

Geologic Hazards and Roof Stability in Coal Mines

Although roof and rib fall fatalities in U.S. coal mines have greatly decreased because of technological advances (e.g., roof bolting, canopies, automatic temporary roof sup-ports (ATRS), longwall mining, rib support, and screening), fatalities (figure 1) and injuries (figure 2) continue to plague U.S. undeground coal miners.
