Abstract :
Considering the main affect factors of displacement of rockstrata around deep roadway under dynamic pressure, using PSO-BP and BP network respectively to forecast the displacement of rockstrata around deep roadway under dynamic pressure. As a result, it comes to a conclusion that the convergence speed and the predicted accuracy of PSO-BP network are obviously better than that of BP network.
