Abstract
To prevent cutter roof failure, the U.S. Bureau of Mines recommends staggering of crosscuts. Adding more roof supports such as trusses and cribbing was found to effectively support the roof in areas of clastic dikes. The Bureau warns, however, that these methods were only successful when employed shortly after mining, so it would pay to be on a lookout for the dikes.
