【Abstract】 As an extensively acknowledged bolting design method for coal roadway support, the dynamic information design has two obvious characters, that is, it is a dynamic process, in which all kinds of information are fully utilized. The application of dynamic information design method in the large-section roadway which is difficult to support and influenced by geological structures is illustrated in the S3 total air-return roadway in Changcun coal mine of Lu’an Coal Group. According to the analysis of ground behavior monitoring data, the validity of roadway supporting is evaluated.更多还原
