A New Method for Studying the Roadway Stability

The effect of 5 factors, including roadway width, height, depth, lateral pressure coefficient and comprehensive stress of surrounding rock on the roadway stability by using the method of orthogonal numerical simulation experiment. The experiment results show that all these factors have an effect on the roadway stability, but the significance is not the same. The numerical simulation experiments reflect the theoretical analysis, which indicates that these methods are highly effective concerning the study on the roadway stability.
