Paper presented at the Gulf Rocks 2004, the 6th North America Rock Mechanics Symposium (NARMS), June 5–9, 2004
Paper Number: ARMA-04-464
... ABSTRACT: Cyclic loading (fatigue) tests were performed on thick-wall hollow cylinders of reservoir rock material. The number of cycles to failure follows a log relationship with the peak cyclic load, for cycles less than 100 and peak loads less than 87% of the base hole collapse strength...

All of these equations were developed for, and were calibrated with, pillars in a large room-and-pillar area such that the loading could be determined using the "tributary-area" theory. In order to account for the abutment loads associated with full-extraction mining, the...
