ABSTRACT

Since there are many factors which would influence the supporting design of the soft rock roadway, and it belongs to the nonlinear problem, the traditional mechanical and mathematical methods can not solve these problems accurately (Yang & Wang 2006). With the ability of high level of self learning, the adaptability and nonlinear mapping, the BP neural network can be widely used in the optimization of the roadway supporting plan (Zhu et al. 2005, Gao 2003, Wei et al. 2010).
