Abstract: Forecasting the mining subsidence is a prerequisite for reducing or preventing the mining subsidence tragedy. But it is hard to apply the traditional probability integral to forecasting the complex solution mining subsidence. So sufficiently considering the anisotropic overburden under complex geological conditions and the irregular rock salt cavern, a new probability integral 3D forecast model is created. And the parameters of 3D forecast model are studied from mechanics angle; and the relation between the model parameters and overburden mechanical parameters is got. The model can exactly forecast the mining subsidence that is caused by complex geological conditions and the irregular working out area.

Key words: rock salt cavern, mining subsidence, new probability integral, forecast model
