Abstract:Purpose: The stability of surrounding rock is one of the important research contents in the field of geotechnical engineering. Poor surrounding rock may cause the collapse of underground projects such as tunnels and mines. To ensure the safe construction and stability of underground projects. Method: After fully investigating and analyzing the stope structural parameters and ground pressure control of a certain ore section in a certain mining area, this study selected the more effective ones in a certain ore section based on the occurrence conditions of the ore body, geological occurrence, and the actual situation of the roof and floor. For representative sections, a similar model test method was used to establish an indoor test model around the point-column roof control to simulate and analyze the stability of the stope during the underground mining process of the mine. Results: As the inclination angle of the ore body increases, the deformation of the surrounding rock increases. Under empty conditions, that is, only the middle pillars are left and no point pillars are left, the roof will be damaged on a large scale and the surface may collapse, causing safety accidents. Conclusion: This study should reserve point pillars to control ground pressure and prevent and control ground pressure impact. Significance: The research results have important theoretical and practical significance in guiding the safe mining and utilization of ore bodies in this mining area.
