Combining modern assessment methods to improve understanding of longwall geomechanics

Ongoing, collaborative research between CSIRO's Exploration and Mining and Strata Control Technology has resulted in abetter understanding of rock failure mechanisms around longwall extraction. Failure has occurred further ahead of theretreating face than predicted by conventional longwall geomechanics theory .In some cases significant failure has beendetected several hundred metres ahead of the face position with demonstrated influences of...
