Two existing predictive methods were chosen for evaluation; an influence function (Gals Theory) and a profile function (hyperbolic). These were applied to several field measured subsidence pro¬files over United States coal mines. The effect of homogeneous versus non-homogeneous overburden on surface subsidence is demonstrated and the utilization of Bals Theory as a subsidence predictive method for both types of overburden is examined. The major factor affecting subsidence profile characteristics is the migration of the inflection point toward the centerline of the longwall panel. A computer program was written to aid in the analysis.
