| Abstract: | In this paper, the particle swarm optimization (PSO) algorithm is introduced into the parameter estimation of the mining model of the probabilistic integration method, which is used to estimate the probability integral method.The basic principle of the parameter, the coding method and the construction method of the fitness function are combined.At the same time, the algorithm is validated by using the measured value of the settlement value and the measured value of the coal mine in Hebei Province as the evaluation criterion of the inversion accuracy.Improving the accuracy of mining subsidence will have a certain reference value. |
