Parameters estimation in surface subsidence modelling

摘要

The aim of the surface subsidence modelling is efficient protection of the communities living on the mining affected areas. Furthermore, the more accurately the parameters of the prediction model are estimated, the more reliable the prognoses are. The parameters not only should have physical sense, but they also should be established for the local conditions of the minerals exploitation. The model, which is based on the influence function, of surface deformation prognosis caused by water, gas or oil exploitation is presented in this paper. The method of the parameters estimation in the local mining and geological condition are shown.
