Apply artificial intelligence methods to solve underground engineering problems. First, the factors affecting the displacement of the surrounding rock of the mine roadway are analyzed, and the four indexes that affect the displacement of the roadway are used as the input layer of the neural network. Then, the approach rate of the roadway is used as the output layer of the network to construct the neural network prediction model of the roadway surrounding rock displacement. Finally, learn and train the model. The prediction result shows that it has a certain practical value.
