This paper describes a study to assess the redistribution of mining-induced stress associated with longwall panel extraction. The objective of this study was to assess the performance of various chain pillar configurations on gate road entry stability. Field measurements were collected and analyzed to develop profiles of the stress redistribution occurring in the gate road chain pillars during longwall panel retreat mining. A better understanding of the redistribution of stress will allow for improved gate road design by more accurately defining the loads imposed on chain pillars.
