Abstract
Over the past 15 years, roof fall rates have decreased by two-thirds in U.S. coal mines and by even more in regions where the roof is weakest. This remarkable reduction in the number of roof falls has been accomplished with more effective roof support systems. The purpose of this paper is to present an empirical design methodology that uses real-world data to quantify the basic roof-support concepts that have been successful in the United States. A new computer package, called Analysis of Mine Roof Support (AMRS), implements the design methodology.
