    Abstract:

    Based on the new probability integral 3D model for forecasting the solution mining subsidence, the transfer rule of superincumbent strata in mining subsidence is studied and a prediction model of stratification transfer for mining subsidence is developed. The model can take into account of the impacts of features of different rock strata on mining subsidence and improve prediction precision of irregular goaf. Based on the situation that it’s hard to get the analytical solution of the model with triple integral, the numerical algorithm of the model is supplied. With the superposition principle theory, a prediction model of multicavern mining subsidence is developed. With the application in ground subsidence prediction of oilgas storage in Jintan, it proves that the transfer prediction model holds higher precision than those of traditional models
