Study on Inversion of Mining Subsidence Based on PSO-BP Algorithm forOkada Model

Abstract

This paper makes a systematic research of the Okada dislocation theory. The application of the theory in the mining subsidence is analyzed. And the method of inversion based on the PSO-BP algorithm has been presented. Through searching for the simulating value of the objective function and comparing with the field observation, the mining subsi- dence mechanism and movement law was studied in depth.
