Description:   A field geotechnical study in a longwall mine in southern Illinois, which included surface and underground instrumentation and monitoring, was done in order to examine subsidence characteristics, stress and deformation changes in chain pillars, roof, pillar and floor deformations, and relationships between surface subsidence and underground strata behaviour.  The subsidence profiles were described in detail and subsidence as a function of time or face position was explained.
