This method is based on the preliminary model, using simulated AC curve instead of AC curve to do the inversion, and it can get very high resolution of inversion result.

Preliminary application of this model shows that it can bridge the gap between management system and information systems, thus greatly improve the adaptability and development efficiency of IS.

The author makes the proposal of establishing a preliminary underground gas drainage numerical model, which is the equivalent of boundary conditions and shift forward of initial conditions.
