After being set state load, optimized timbering adds support yielding deformation, increases the load-carrying ability and improves the effect of controlling the surrounding rock.
Lastly, timbering parameter is studied by utilizing Artificial NeuralNetwork (ANN), and put forward using Discrete Element Method (DEM) to confirm 2nd support time.
