Abstract: For the controlling problem of extreme soft surrounding rock influenced by mining, on the basis of original supporting design, numerical simulation way is used to carry out supporting parameters optimization design for extreme soft surrounding rock roadway in Guizhou Xingyi mining area. Nine kinds of computational schemes are designed according to support style of bolt, spray, net, cable and beam as well as the factors of bolting row and line space, bolting length. FLAC software is used to calculate the nine schemes, and the optimal support scheme is achieved. The deformation of the roadway surrounding rock is well controlled by using the optimal support scheme.
