It has been pointed out that the influence factor concerning estimation of the surface subsidence is, in strict meaning, to be determined not only by the area mined out but also by the property of the ground, and. that the methods to determine the factor heretofore in use, such as Bails' method, have no theoretical background. A method to determine the factor taking into account the surface subsidence curve obtained from field survey has been suggested, besides a simple and convenient method for the case the data are not available has also been proposed.
