| Abstract: | The aided design system of three- dimension roadway driven along next goal bolt supporting was developed by using ANSYS finite element numerical simulation software. The numerical simulation analysis was carried out on the function mechanism of bolts supporting of roadway driven along next goal under horizontal stress field. It mainly researched on the effect of bolt supporting with different lengths and different initial pretensions on the stability of roadway hangingwall and footwall under horizontal stress field. The movement rule of the hangingwall and footwall along the roadway was analyzed. Some conclusions that had significance to guide practice were put forward. |
