Deformation and Failure Laws of Surrounding Rocks of Coal Roadways under High Dynamic Load and Intelligent Prediction

Under high dynamic load, roadway deformation and failure may occur, posing great challenges. As for now, few studies have been carried out on the impacts of various factors surrounding rocks under not to mention those intelligent prediction laws. This paper fills these research gaps by studying characteristics method load. The finite difference software Flac3D was used analyze influences buried depth, lithology, side pressure coefficient stability a model constructed Finally, influence their weight obtained can be predicted in line with BP neural network theory. results show that effect is good, accuracy.
