Abstract
Longwall mining results in a redistribution of strata stresses, which affect the natural insitu permeability regime. After a brief review of current conceptual models used to explain this phenomena, a comprehensive examination is made of all results obtained from investigations undertaken by Nottingham University to monitor insitu permeability changes under field conditions. To facilitate a unified approach, all the original results, where available, have been re-analysed using cumulative difference analysis. The results are discussed with respect to three identifiable areas which occur around a longwall panel: ahead of the face line, the face end and the ribside pillar.
